python: Use-after-free of a server-side SSLContext when sni_callback switches contexts
A flaw was found in Python. A remote, unauthenticated TLS client can cause a use-after-free in a server that uses SSLContext.snicallback to assign a different SSLSocket.context when selecting a certificate per server name, if nothing else keeps the original SSLContext alive. This can crash the...

Frameless BITB Une nouvelle approche du Browser In The Browser BITB sans utiliser d'iframes, permettant de contourner les framebusters traditionnels implémentés par les pages de connexion comme celles de Microsoft. Ce code POC est conçu pour utiliser ce nouveau BITB avec Evilginx, ainsi qu'un...
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...
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: 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: 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: 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: 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: 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...
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: 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: 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: ipc: limit next_id allocation to the valid ID range
A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...
