| CVE-2026-53252 | 1 Linux | 1 Linux Kernel | 2026-06-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: fix memory leak in error path of hci_alloc_dev() Early failures in Bluetooth HCI UART configuration leak SRCU percpu memory. When device initialization fails before hci_register_dev() completes, the HCI_UNREGISTER flag is never set. As a result, when the device reference count reaches zero, bt_host_release() evaluates this flag as false and falls back to a direct kfree(hdev). Because hci_release_dev() is bypassed, the SRCU struct initialized early in hci_alloc_dev() is never cleaned up, resulting in a leak of percpu memory. Fix the leak by explicitly calling cleanup_srcu_struct() in the fallback (unregistered) branch of bt_host_release() before freeing the device. | ||||
| CVE-2026-53213 | 1 Linux | 1 Linux Kernel | 2026-06-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/vc4: fix krealloc() memory leak Don't just overwrite the original pointer passed to krealloc() with its return value without checking latter: MEM = krealloc(MEM, SZ, GFP); If krealloc() returns NULL, that erases the pointer to the still allocated memory, hence leaks this memory. Instead, use a temporary variable, check it's not NULL and only then assign it to the original pointer: TMP = krealloc(MEM, SZ, GFP); if (!TMP) return; MEM = TMP; While on it, use krealloc_array(). | ||||
| CVE-2026-53227 | 1 Linux | 1 Linux Kernel | 2026-06-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: fix possible kfree_skb of ERR_PTR After the patch in the "Fixes" tag, the allocation of the "reply" skb can happen either before or after locking the ovs_mutex. However, error cleanups still follow the classical reversed order, assuming "reply" is allocated before locking: it is freed after unlocking. If "reply" allocation happens after locking the mutex and it fails, "reply" is left with an ERR_PTR, and execution jumps to the correspondent cleanup stage which will try to free an invalid pointer. Fix this by setting the pointer to NULL after having saved its error value. | ||||
| CVE-2026-53140 | 1 Linux | 1 Linux Kernel | 2026-06-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Fix vaddr leak when indirect CSD has zeroed workgroups v3d_rewrite_csd_job_wg_counts_from_indirect() maps both the indirect buffer and the workgroup buffer and is expected to release them before returning. When any of the workgroup counts read from the buffer is zero, the function bailed out early and skipped the cleanup, leaking the vaddr mappings of both BOs. Jump to the cleanup path instead of returning directly, so the mappings are always dropped. | ||||
| CVE-2026-53060 | 1 Linux | 1 Linux Kernel | 2026-06-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dm cache metadata: fix memory leak on metadata abort retry When failing to acquire the root_lock in dm_cache_metadata_abort because the block_manager is read-only, the temporary block_manager created outside the root_lock is not properly released, causing a memory leak. Reproduce steps: This can be reproduced by reloading a new table while the metadata is read-only. While the second call to dm_cache_metadata_abort is caused by lack of support for table preload in dm-cache, mentioned in commit 9b1cc9f251af ("dm cache: share cache-metadata object across inactive and active DM tables"), it exposes the memory leak in dm_cache_metadata_abort when the function is called multiple times. Specifically, dm-cache fails to sync the new cache object's mode during preresume, creating the reproducer condition. This issue could also occur through concurrent metadata_operation_failed calls due to races in cache mode updates, but the table preload scenario below provides a reliable reproducer. 1. Create a cache device with some faulty trailing metadata blocks dmsetup create cmeta <<EOF 0 200 linear /dev/sdc 0 200 7992 error EOF dmsetup create cdata --table "0 131072 linear /dev/sdc 8192" dmsetup create corig --table "0 262144 linear /dev/sdc 262144" dd if=/dev/zero of=/dev/mapper/cmeta bs=4k count=1 oflag=direct dmsetup create cache --table "0 131072 cache /dev/mapper/cmeta \ /dev/mapper/cdata /dev/mapper/corig 128 1 writethrough smq 0" 2. Suspend and resume the cache to start a new metadata transaction and trigger metadata io errors on the next metadata commit. dmsetup suspend cache dmsetup resume cache 3. Write to the cache device to update metadata fio --filename=/dev/mapper/cache --name test --rw=randwrite --bs=4k \ --randrepeat=0 --direct=1 --size 64k 4. Preload the same table dmsetup reload cache --table "$(dmsetup table cache)" 5. Resume the new table. This triggers the memory leak. dmsetup suspend cache dmsetup resume cache kmemleak logs: <snip> unreferenced object 0xffff8880080c2010 (size 16): comm "dmsetup", pid 132, jiffies 4294982580 hex dump (first 16 bytes): 00 38 b9 07 80 88 ff ff 6a 6b 6b 6b 6b 6b 6b a5 ... backtrace (crc 3118f31c): kmemleak_alloc+0x28/0x40 __kmalloc_cache_noprof+0x3d9/0x510 dm_block_manager_create+0x51/0x140 dm_cache_metadata_abort+0x85/0x320 metadata_operation_failed+0x103/0x1e0 cache_preresume+0xacd/0xe70 dm_table_resume_targets+0xd3/0x320 __dm_resume+0x1b/0xf0 dm_resume+0x127/0x170 <snip> | ||||
| CVE-2026-53211 | 1 Linux | 1 Linux Kernel | 2026-06-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_meta_bridge: fix stale stack leak via IIFHWADDR register NFT_META_BRI_IIFHWADDR declares its destination register with len = ETH_ALEN (6 bytes), which the register-init tracking rounds up to two 32-bit registers (8 bytes). nft_meta_bridge_get_eval() then does memcpy(dest, br_dev->dev_addr, ETH_ALEN), writing only 6 bytes and leaving the upper 2 bytes of the second register as uninitialised nft_do_chain() stack. A downstream load of that register span leaks those stale bytes to userspace. Zero the second register before the memcpy so the full declared span is written. | ||||
| CVE-2026-0646 | 1 Rockwellautomation | 1 Flex I/o Ethernet/ip Adapter | 2026-06-26 | N/A |
| A denial-of-service security issue exists within the 1794-AENTR adapter due to improper memory handling of CIP protocol requests. This vulnerability can result in the adapter faulting and losing connection to its associated I/O modules, requiring a manual reset to recover. | ||||
| CVE-2026-53065 | 1 Linux | 1 Linux Kernel | 2026-06-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: sti: use managed regmap_field allocations The regmap_field objects allocated at player init are never freed and may leak resources if the driver is removed. Switch to devm_regmap_field_alloc() to automatically limit the lifetime of the allocations the lifetime of the device. | ||||
| CVE-2026-53261 | 1 Linux | 1 Linux Kernel | 2026-06-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: devlink: Release nested relation on devlink free devlink relation state is normally released from devl_unregister(), which calls devlink_rel_put(). This misses devlink instances that get a nested relation before registration and then fail probe before devl_register() is reached. That flow can happen for SFs. The child devlink gets linked to its parent before registration, then a later probe error calls devlink_free() directly. Since the instance was never registered, devl_unregister() is not called and devlink->rel is leaked. Release any pending relation from devlink_free() as well. The registered path is unchanged because devl_unregister() already clears devlink->rel before devlink_free() runs. | ||||
| CVE-2024-6875 | 1 Redhat | 1 Jboss Data Grid | 2026-06-26 | 6.5 Medium |
| A vulnerability was found in the Infinispan component in Red Hat Data Grid. The REST compare API may have a buffer leak and an out of memory error can occur when sending continual requests with large POST data to the REST API. | ||||
| CVE-2026-53210 | 1 Linux | 1 Linux Kernel | 2026-06-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: tee: shm: fix shm leak in register_shm_helper() register_shm_helper() allocates shm before calling iov_iter_npages(). If iov_iter_npages() returns 0, the function jumps to err_ctx_put and leaks shm. This can be triggered by TEE_IOC_SHM_REGISTER with struct tee_ioctl_shm_register_data where length is 0. Jump to err_free_shm instead. | ||||
| CVE-2026-53127 | 1 Linux | 1 Linux Kernel | 2026-06-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: block: fix zones_cond memory leak on zone revalidation error paths When blk_revalidate_disk_zones() fails after disk_revalidate_zone_resources() has allocated args.zones_cond, the memory is leaked because no error path frees it. | ||||
| CVE-2026-52937 | 1 Linux | 1 Linux Kernel | 2026-06-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: tap: fix stack info leak in tap_ioctl() SIOCGIFHWADDR In the SIOCGIFHWADDR path, tap_ioctl() copies 16 bytes of an uninitialised on-stack struct sockaddr_storage to userspace via ifr_hwaddr, but netif_get_mac_address() only writes sa_family and dev->addr_len (6 for Ethernet) bytes, leaving sa_data[6..13] uninitialised. Those 8 trailing bytes leak kernel stack contents; SIOCGIFHWADDR on a macvtap chardev returns kernel .text and direct-map pointers, defeating KASLR. Initialise ss at declaration. | ||||
| CVE-2026-53079 | 1 Linux | 1 Linux Kernel | 2026-06-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net_sched: fix skb memory leak in deferred qdisc drops When the network stack cleans up the deferred list via qdisc_run_end(), it operates on the root qdisc. If the root qdisc do not implement the TCQ_F_DEQUEUE_DROPS flag the packets queue to free are never freed and gets stranded on the child's local to_free list. Fix this by making qdisc_dequeue_drop() aware of the root qdisc. It fetches the root qdisc and check for the TCQ_F_DEQUEUE_DROPS flag. If the flag is present, the packet is appended directly to the root's to_free list. Otherwise, drop it directly as it was done before the optimization was implemented. | ||||
| CVE-2026-52996 | 1 Linux | 1 Linux Kernel | 2026-06-24 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix durable fd leak on ClientGUID mismatch in durable v2 open ksmbd_lookup_fd_cguid() returns a ksmbd_file with its refcount incremented via ksmbd_fp_get(). parse_durable_handle_context() in the DURABLE_REQ_V2 case properly releases this reference on every path inside the ClientGUID-match branch, either by calling ksmbd_put_durable_fd() or by transferring ownership to dh_info->fp for a successful reconnect. However, when an entry exists in the global file table with the same CreateGuid but a different ClientGUID, the code simply falls through to the new-open path without dropping the reference obtained from ksmbd_lookup_fd_cguid(). Per MS-SMB2 section 3.3.5.9.10 ("Handling the SMB2_CREATE_DURABLE_HANDLE_REQUEST_V2 Create Context"), the server MUST locate an Open whose Open.CreateGuid matches the request's CreateGuid AND whose Open.ClientGuid matches the ClientGuid of the connection that received the request. If no such Open is found, the server MUST continue with the normal open execution phase. A CreateGuid hit with a ClientGUID mismatch is therefore the "Open not found" case: proceeding with a new open is correct, but the reference obtained purely as a side effect of the lookup must not be leaked. Repeated requests that hit this mismatch pin global_ft entries, prevent __ksmbd_close_fd() from ever running for the corresponding files, and defeat the durable scavenger, leading to long-lived resource leaks. Release the reference in the mismatch path and clear dh_info->fp so subsequent logic does not mistake a non-matching lookup result for a reconnect target. | ||||
| CVE-2026-56368 | 1 Imagemagick | 1 Imagemagick | 2026-06-24 | 3.7 Low |
| ImageMagick before 7.1.2-15 contains a memory leak vulnerability in multiple coders that write raw pixel data where allocated objects are not properly freed. Attackers can trigger this leak by processing specially crafted images, causing memory exhaustion and denial of service. | ||||
| CVE-2023-3576 | 3 Fedoraproject, Libtiff, Redhat | 3 Fedora, Libtiff, Enterprise Linux | 2026-06-23 | 5.5 Medium |
| A memory leak flaw was found in Libtiff's tiffcrop utility. This issue occurs when tiffcrop operates on a TIFF image file, allowing an attacker to pass a crafted TIFF image file to tiffcrop utility, which causes this memory leak issue, resulting an application crash, eventually leading to a denial of service. | ||||
| CVE-2026-48141 | 1 Ni | 3 Grpc-device, Instrumentstudio, Ni Grpc Device Server | 2026-06-22 | 5.3 Medium |
| There is a memory leak in NI grpc-device BeginSidebandStream that may result in denial of service due to memory exhaustion. This affects NI grpc-device 2.17.0 and prior versions. | ||||
| CVE-2026-46083 | 1 Linux | 1 Linux Kernel | 2026-06-19 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: spi: fix resource leaks on device setup failure Make sure to call controller cleanup() if spi_setup() fails while registering a device to avoid leaking any resources allocated by setup(). | ||||
| CVE-2026-46065 | 1 Linux | 1 Linux Kernel | 2026-06-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: fbdev: defio: Disconnect deferred I/O from the lifetime of struct fb_info Hold state of deferred I/O in struct fb_deferred_io_state. Allocate an instance as part of initializing deferred I/O and remove it only after the final mapping has been closed. If the fb_info and the contained deferred I/O meanwhile goes away, clear struct fb_deferred_io_state.info to invalidate the mapping. Any access will then result in a SIGBUS signal. Fixes a long-standing problem, where a device hot-unplug happens while user space still has an active mapping of the graphics memory. The hot- unplug frees the instance of struct fb_info. Accessing the memory will operate on undefined state. | ||||
