kernel: Linux kernel io_uring: Local privilege escalation, information disclosure, or denial of service via use-after-free
A flaw was found in the Linux kernel's iouring subsystem. A local attacker with low privileges could exploit a use-after-free vulnerability when the sq-thread object is prematurely released while still being accessed by the iouringshowfdinfo function. This flaw could lead to privilege escalation,...

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-005675 advisory. In the Linux kernel, the following vulnerability has been resolved: iouring: wait interruptibly for request completions on exit WHen the ring exits, cleanup is done...
Linux kernel io_uring Buffer Overflow DoS
The vulnerability of the iolinkskb function in the iouring/notif.c module of the Linux kernel’s asynchronous input/output interface is related to incorrect comparisons. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of protect...
kernel: Linux kernel: Data corruption and system instability due to improper io_uring/net buffer handling
A flaw was found in the Linux kernel's iouring/net component. This vulnerability arises when ring provided buffers are partially committed during network operations, particularly when MSGWAITALL is enabled or with streaming sockets. A local attacker could exploit this by causing multiple socket...

SUSE CVE-2026-23113
In the Linux kernel, the following vulnerability has been resolved: iouring/io-wq: check IOWQBITEXIT inside work run loop Currently this is checked before running the pending work. Normally this is quite fine, as work items either end up blocking which will create a new worker for other items, or...

CVE-2026-23113
A flaw was found in the Linux kernel's iouring subsystem. When io-wq worker threads process extremely long-running I/O operations such as large reads from /dev/msr devices, the exit path may be delayed for an extended period because the IOWQBITEXIT flag is only checked before the work loop begins...
