CVE-2026-74535

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: avoid deadlocks in isosocktimeout isosocktimeout takes locksock, so sync disabling the timer while holding that lock may deadlock. isosocktimeout may also run concurrently with isoconndel, which leads to UAF Task ...

EUVD-2026-59731

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: lock sk in isoconnectind Accessing isopisk-conn requires locksock, which is not taken in the "ev3" part of isoconnectind. It may also be NULL if socket has transitioned away from the LISTEN/CONNECT states before...

CVE-2026-74537

The CVE-2026-74537 entry concerns the Linux kernel Bluetooth ISO path. A use-after-free could occur when dereferencing conn->sk in iso_conn_ready because the socket was accessed without holding a lock or a refcount. The fix adds a socket refcount in iso_conn_ready and rechecks socket validity ...

CVE-2026-74490

In the Linux kernel, the following vulnerability has been resolved: tipc: avoid use-after-free in poll trace queue dumps TIPC socket tracepoints dump queue state through tipcskdump. Most queue-dump callsites already serialize that walk under the socket lock or sk-sklock.slock, but tipcpoll calls...

CVE-2026-74268

This CVE describes a Linux kernel vulnerability where a child socket can inherit BPF sock_ops cb flags from the listener through sk_clone_lock(), leading to a crash or compromised handling if its setup fails in tcp_v4_syn_recv_sock() or tcp_v6_syn_recv_sock(). The root cause is that, on forced-cl...

CVE-2026-72447

CVE-2026-72447 (Linux kernel SCTP diag leak) : The vulnerability concerns SCTP_DIAG endpoint dumping in the Linux kernel, where SCTP endpoint address lists were read without holding lock_sock(), allowing concurrent socket operations (e.g., bindx) to change data. This race can cause nla_reserve() ...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: net/rds: Fixed a circular locking dependency in rdstcptune syzbot reported a circular locking dependency in rdstcptune, where sknetrefcntupgrade is called while holding the socket lock:...

CVE-2026-64518

A flaw was found in the Linux kernel's TCP implementation. An out-of-bounds access vulnerability exists when the lockdepsockisheld function is called with a tcptimewaitsock object. This occurs because the tcptimewaitsock object lacks the necessary sk-sklock, leading to an incorrect lockdep...
