Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update
An update for kernel is now available for Red Hat Enterprise Linux 8.4 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.4 Extended Update Support Long-Life Add-On. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerabilit...
kernel: netfilter: flowtable: publish GC-visible tuple last
A flaw was found in the netfilter flowtable component of the Linux kernel. This vulnerability occurs due to a timing issue where the system's garbage collection can free a network flow while it is still being set up. This can lead to a 'use-after-free' condition, where the system attempts to acce...
kernel: xfrm: policy: fix use-after-free on inexact bin in xfrm_policy_bysel_ctx()
A flaw was found in the Linux kernel. A race condition exists in the xfrm policy handling, specifically within the xfrmpolicybyselctx function. This flaw allows for a use-after-free vulnerability, where memory is accessed after it has been released. This can lead to system instability or a denial...
kernel: RDMA/rxe: Fix a use-after-free problem in rxe_mmap
A flaw was found in the Linux kernel's RDMA/rxe component. A race condition in the rxemmap function, which manages memory for Remote Direct Memory Access RDMA operations, can lead to a use-after-free vulnerability. A local attacker could exploit this timing issue to cause a system crash, resultin...
kernel: xfrm: fix stale skb->prev after async crypto steals a GSO segment
A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises when asynchronous cryptographic operations incorrectly handle network packet segments, leaving a pointer to memory that has already been released. An attacker could potentially exploit this use-after-free condition t...
kernel: RDMA/rxe: Fix responder UAF on IB_QP_MAX_DEST_RD_ATOMIC modify_qp
A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the rxe component. A local, unprivileged user could exploit a race condition during a queue pair modification operation. This could lead to a use-after-free vulnerability, allowing the attacker ...
kernel: xfrm: input: hold netns during deferred transport reinjection
A flaw was found in the Linux kernel's xfrm input component. The transport-mode reinjection process, which handles network packet re-injection, stores a network namespace pointer that must remain valid until a deferred callback completes. However, a missing reference count for the network namespa...
kernel: gfs2: Fix use-after-free in iomap inline data write path
A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...
kernel: ALSA: 6fire: fix use-after-free on disconnect
A flaw was found in the Linux kernel's ALSA 6fire USB audio device driver. During the disconnection process of a 6fire USB audio device, a use-after-free vulnerability occurs. This happens when the system attempts to write to memory that has already been deallocated, which can lead to memory...
kernel: sctp: purge outqueue on stale COOKIE-ECHO handling
A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. This vulnerability, a use-after-free, occurs when the system processes a Stale Cookie ERROR during the setup or reconfiguration of an SCTP association. A remote attacker could exploit this by sending...
CVE-2025-60458
CVE-2025-60458 UxPlay 1.72 RTSP TEARDOWN Double Free Vulnerability Description UxPlay version 1.72 contains a double free vulnerability in its RTSP request handling logic. A remote attacker can trigger multiple calls to free on the same heap memory object by sending a specially crafted RTSP...
vsock_poc
vsockpoc Исследование ошибки, стоящей за CVE-2021-26708 В этом репозитории содержатся краткие заметки о CVE-2021-26708 и о том, как эту ошибку можно превратить в примитив записи типа Use After Free. Приведённый здесь PoC — это не полноценный эксплойт, а лишь мой тестовый стенд, который я...
