Description

This security bulletin contains information about 1 vulnerability.


1) Race condition (CVE-ID: CVE-2026-46028)

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper state management in the algif_aead AF_ALG AEAD request handling when processing asynchronous AEAD AIO requests. A local user can trigger concurrent socket activity to cause a denial of service.

The issue arises because in-flight operations depend on a mutable socket-wide IV buffer that can be changed before the original request completes.
