CVE-2026-25953 1 Freerdp 1 Freerdp 2026-04-17 9.8 Critical
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_AppUpdateWindowFromSurface` reads from a freed `xfAppWindow` because the RDPGFX DVC thread obtains a bare pointer via `xf_rail_get_window` without any lifetime protection, while the main thread can concurrently delete the window through a fastpath window-delete order. Version 3.23.0 fixes the issue.
CVE-2026-25955 1 Freerdp 1 Freerdp 2026-04-17 9.8 Critical
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_AppUpdateWindowFromSurface` reuses a cached `XImage` whose `data` pointer references a freed RDPGFX surface buffer, because `gdi_DeleteSurface` frees `surface->data` without invalidating the `appWindow->image` that aliases it. Version 3.23.0 fixes the issue.
CVE-2026-25959 1 Freerdp 1 Freerdp 2026-04-17 9.8 Critical
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_cliprdr_provide_data_` passes freed `pDstData` to `XChangeProperty` because the cliprdr channel thread calls `xf_cliprdr_server_format_data_response` which converts and uses the clipboard data without holding any lock, while the X11 event thread concurrently calls `xf_cliprdr_clear_cached_data` → `HashTable_Clear` which frees the same data via `xf_cached_data_free`, triggering a heap use after free. Version 3.23.0 fixes the issue.
CVE-2026-25997 1 Freerdp 1 Freerdp 2026-04-17 9.8 Critical
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_clipboard_format_equal` reads freed `lastSentFormats` memory because `xf_clipboard_formats_free` (called from the cliprdr channel thread during auto-reconnect) frees the array while the X11 event thread concurrently iterates it in `xf_clipboard_changed`, triggering a heap use after free. Version 3.23.0 fixes the issue.
CVE-2026-26986 1 Freerdp 1 Freerdp 2026-04-17 7.5 High
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `rail_window_free` dereferences a freed `xfAppWindow` pointer during `HashTable_Free` cleanup because `xf_rail_window_common` calls `free(appWindow)` on title allocation failure without first removing the entry from the `railWindows` hash table, leaving a dangling pointer that is freed again on disconnect. Version 3.23.0 fixes the vulnerability.
CVE-2026-22040 2 Emqx, Nanomq 2 Nanomq, Nanomq 2026-04-17 5.3 Medium
NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. In version 0.24.6, by generating a combined traffic pattern of high-frequency publishes and rapid reconnect/kick-out using the same ClientID and massive subscribe/unsubscribe jitter, it is possible to reliably trigger heap memory corruption in the Broker process, causing it to exit immediately with SIGABRT due to free(): invalid pointer. As of time of publication, no known patched versions are available.
CVE-2026-3924 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-04-17 7.5 High
use after free in WindowDialog in Google Chrome prior to 146.0.7680.71 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
CVE-2026-6068 1 Nasm 2 Nasm, Netwide Assembler 2026-04-16 6.5 Medium
NASM contains a heap use after free vulnerability in response file (-@) processing where a dangling pointer to freed memory is stored in the global depend_file and later dereferenced, as the response-file buffer is freed before the pointer is used, allowing for data corruption or unexpected behavior.
CVE-2026-20844 1 Microsoft 18 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 15 more 2026-04-16 7.4 High
Use after free in Windows Clipboard Server allows an unauthorized attacker to elevate privileges locally.
CVE-2026-20953 1 Microsoft 9 365 Apps, Office, Office 2016 and 6 more 2026-04-16 8.4 High
Use after free in Microsoft Office allows an unauthorized attacker to execute code locally.
CVE-2026-20830 1 Microsoft 1 Windows Server 2025 2026-04-16 7 High
Concurrent execution using shared resource with improper synchronization ('race condition') in Capability Access Management Service (camsvc) allows an authorized attacker to elevate privileges locally.
CVE-2026-20854 1 Microsoft 5 Windows 11 24h2, Windows 11 24h2, Windows 11 25h2 and 2 more 2026-04-16 7.5 High
Use after free in Windows Local Security Authority Subsystem Service (LSASS) allows an authorized attacker to execute code over a network.
CVE-2026-20867 1 Microsoft 16 Windows 10 1809, Windows 10 21h2, Windows 10 21h2 and 13 more 2026-04-16 7.8 High
Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Management Services allows an authorized attacker to elevate privileges locally.
CVE-2026-20871 1 Microsoft 14 Windows 10 21h2, Windows 10 21h2, Windows 10 22h2 and 11 more 2026-04-16 7.8 High
Use after free in Desktop Windows Manager allows an authorized attacker to elevate privileges locally.
CVE-2026-20950 1 Microsoft 11 365 Apps, Excel, Excel 2016 and 8 more 2026-04-16 7.8 High
Use after free in Microsoft Office Excel allows an unauthorized attacker to execute code locally.
CVE-2026-20952 1 Microsoft 9 365 Apps, Office, Office 2016 and 6 more 2026-04-16 8.4 High
Use after free in Microsoft Office allows an unauthorized attacker to execute code locally.
CVE-2026-39316 1 Openprinting 1 Cups 2026-04-16 4 Medium
OpenPrinting CUPS is an open source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and prior, a use-after-free vulnerability exists in the CUPS scheduler (cupsd) when temporary printers are automatically deleted. cupsdDeleteTemporaryPrinters() in scheduler/printers.c calls cupsdDeletePrinter() without first expiring subscriptions that reference the printer, leaving cupsd_subscription_t.dest as a dangling pointer to freed heap memory. The dangling pointer is subsequently dereferenced at multiple code sites, causing a crash (denial of service) of the cupsd daemon. With heap grooming, this can be leveraged for code execution.
CVE-2026-5883 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-04-16 8.8 High
Use after free in Media in Google Chrome prior to 147.0.7727.55 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-26983 1 Imagemagick 1 Imagemagick 2026-04-16 5.3 Medium
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, the MSL interpreter crashes when processing a invalid `<map>` element that causes it to use an image after it has been freed. Versions 7.1.2-15 and 6.9.13-40 contain a patch.
CVE-2026-27283 3 Adobe, Apple, Microsoft 4 Indesign, Indesign Desktop, Macos and 1 more 2026-04-16 7.8 High
InDesign Desktop versions 20.5.2, 21.2 and earlier are affected by a Use After Free vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
