kernel: crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg

A race condition was found in the Linux kernel cryptographic user API, AFALG in the way concurrent writes to the same AFALG socket are handled. Interleaved data and inconsistent internal socket state may result. A local user could use this flaw to crash the system or corrupt cryptographic operati...

ROS-20260825-73-0005

The vulnerability of the afalgsendmsg function in the crypto/afalg.c module of the Linux kernel’s cryptographic subsystem is related to the improper disabling or release of resources. Exploiting this vulnerability could allow a remote attacker to cause service interruptions...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: crypto: afalg - Set merge to zero early in afalgsendmsg. If an error causes afalgsendmsg to abort, ctx-merge may contain a garbage value from the previous loop. This could lead to a crash when afalgsendmsg attempts to perform a...

The vulnerability of the af_alg_sendmsg() function in the crypto/af_alg.c module of the Linux kernel’s cryptographic subsystem allows a hacker to induce a service failure.
