Detailsinfo

A vulnerability was found in Linux Kernel up to 6.3.1 and classified as critical. Affected by this issue is the function raid10_run. The manipulation with an unknown input leads to a memory leak vulnerability. Using CWE to declare the problem leads to CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. Impacted is availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix memleak of md thread In raid10_run(), if setup_conf() succeed and raid10_run() failed before setting 'mddev->thread', then in the error path 'conf->thread' is not freed. Fix the problem by setting 'mddev->thread' right after setup_conf().

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2023-54294 since 12/30/2025. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 319480 (EulerOS Virtualization 2.10.1 : kernel (EulerOS-SA-2026-2022)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 4.19.283, 5.4.243, 5.10.180, 5.15.111, 6.1.28, 6.2.15 or 6.3.2 eliminates this vulnerability.
