CVE-2023-5088 2 Qemu, Redhat 3 Qemu, Advanced Virtualization, Enterprise Linux 2026-02-25 6.4 Medium
A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot.
CVE-2023-46813 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more 2026-02-25 7.0 High
An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it.
CVE-2023-39975 2 Mit, Redhat 2 Kerberos 5, Enterprise Linux 2026-02-25 8.8 High
kdc/do_tgs_req.c in MIT Kerberos 5 (aka krb5) 1.21 before 1.21.2 has a double free that is reachable if an authenticated user can trigger an authorization-data handling failure. Incorrect data is copied from one ticket to another.
CVE-2023-40283 4 Canonical, Debian, Linux and 1 more 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more 2026-02-25 7.8 High
An issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before 6.4.10. There is a use-after-free because the children of an sk are mishandled.
CVE-2023-33952 2 Linux, Redhat 5 Linux Kernel, Enterprise Linux, Enterprise Linux For Real Time and 2 more 2026-02-25 6.7 Medium
A double-free vulnerability was found in handling vmw_buffer_object objects in the vmwgfx driver in the Linux kernel. This issue occurs due to the lack of validating the existence of an object prior to performing further free operations on the object, which may allow a local privileged user to escalate privileges and execute code in the context of the kernel.
CVE-2023-4147 4 Debian, Fedoraproject, Linux and 1 more 9 Debian Linux, Fedora, Linux Kernel and 6 more 2026-02-25 7.8 High
A use-after-free flaw was found in the Linux kernel’s Netfilter functionality when adding a rule with NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
CVE-2023-4921 3 Debian, Linux, Redhat 10 Debian Linux, Linux Kernel, Enterprise Linux and 7 more 2026-02-25 7.8 High
A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in agg_dequeue(). We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8.
CVE-2023-5717 2 Linux, Redhat 5 Linux Kernel, Enterprise Linux, Logging and 2 more 2026-02-25 7.8 High
A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory locations outside of the allocated buffer. We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06.
CVE-2023-0567 3 Php, Php Group, Redhat 3 Php, Php, Enterprise Linux 2026-02-25 7.7 High
In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, password_verify() function may accept some invalid Blowfish hashes as valid. If such invalid hash ever ends up in the password database, it may lead to an application allowing any password for this entry as valid.
CVE-2021-3347 4 Debian, Fedoraproject, Linux and 1 more 10 Debian Linux, Fedora, Linux Kernel and 7 more 2026-02-25 7.8 High
An issue was discovered in the Linux kernel through 5.10.11. PI futexes have a kernel stack use-after-free during fault handling, allowing local users to execute code in the kernel, aka CID-34b1a1ce1458.
CVE-2025-0577 1 Redhat 1 Enterprise Linux 2026-02-25 4.8 Medium
An insufficient entropy vulnerability was found in glibc. The getrandom and arc4random family of functions may return predictable randomness if these functions are called again after the fork, which happens concurrently with a call to any of these functions.
CVE-2020-14381 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-02-25 7.8 High
A flaw was found in the Linux kernel’s futex implementation. This flaw allows a local attacker to corrupt system memory or escalate their privileges when creating a futex on a filesystem that is about to be unmounted. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2023-6932 3 Debian, Linux, Redhat 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more 2026-02-25 7.8 High
A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation. A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread. We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1.
CVE-2022-1650 3 Debian, Eventsource, Redhat 11 Debian Linux, Eventsource, Ceph Storage and 8 more 2026-02-24 8.1 High
Improper Removal of Sensitive Information Before Storage or Transfer in GitHub repository eventsource/eventsource prior to v2.0.2.
CVE-2025-11234 1 Redhat 4 Enterprise Linux, Openshift, Rhel E4s and 1 more 2026-02-24 7.5 High
A flaw was found in QEMU. If the QIOChannelWebsock object is freed while it is waiting to complete a handshake, a GSource is leaked. This can lead to the callback firing later on and triggering a use-after-free in the use of the channel. This can be abused by a malicious client with network access to the VNC WebSocket port to cause a denial of service during the WebSocket handshake prior to the VNC client authentication.
CVE-2020-1472 9 Canonical, Debian, Fedoraproject and 6 more 20 Ubuntu Linux, Debian Linux, Fedora and 17 more 2026-02-23 5.5 Medium
An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC). An attacker who successfully exploited the vulnerability could run a specially crafted application on a device on the network. To exploit the vulnerability, an unauthenticated attacker would be required to use MS-NRPC to connect to a domain controller to obtain domain administrator access. Microsoft is addressing the vulnerability in a phased two-part rollout. These updates address the vulnerability by modifying how Netlogon handles the usage of Netlogon secure channels. For guidelines on how to manage the changes required for this vulnerability and more information on the phased rollout, see How to manage the changes in Netlogon secure channel connections associated with CVE-2020-1472 (updated September 28, 2020). When the second phase of Windows updates become available in Q1 2021, customers will be notified via a revision to this security vulnerability. If you wish to be notified when these updates are released, we recommend that you register for the security notifications mailer to be alerted of content changes to this advisory. See Microsoft Technical Security Notifications.
CVE-2020-1597 3 Fedoraproject, Microsoft, Redhat 6 Fedora, Asp.net Core, Visual Studio 2017 and 3 more 2026-02-23 7.5 High
A denial of service vulnerability exists when ASP.NET Core improperly handles web requests. An attacker who successfully exploited this vulnerability could cause a denial of service against an ASP.NET Core web application. The vulnerability can be exploited remotely, without authentication. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to the ASP.NET Core application. The update addresses the vulnerability by correcting how the ASP.NET Core web application handles web requests.
CVE-2020-1045 3 Fedoraproject, Microsoft, Redhat 7 Fedora, Asp.net Core, Enterprise Linux and 4 more 2026-02-23 7.5 High
<p>A security feature bypass vulnerability exists in the way Microsoft ASP.NET Core parses encoded cookie names.</p> <p>The ASP.NET Core cookie parser decodes entire cookie strings which could allow a malicious attacker to set a second cookie with the name being percent encoded.</p> <p>The security update addresses the vulnerability by fixing the way the ASP.NET Core cookie parser handles encoded names.</p>
CVE-2025-55248 4 Apple, Linux, Microsoft and 1 more 22 Macos, Linux Kernel, .net and 19 more 2026-02-22 4.8 Medium
