AI-suggested

An official patch is available and included in updated Linux kernel packages for Ubuntu 20.04 HWE edge kernels. Users should apply the security updates provided by Ubuntu as detailed in advisory USN-8029-1 to remediate this issue. No additional mitigation steps are required beyond applying the vendor-supplied fixes.

Description

A memory leak vulnerability in the Linux kernel's ARM SCMI power domain driver was fixed. The issue occurs when of_genpd_add_provider_onecell() fails during probe, causing previously created generic power domains to not be removed. This can lead to a memory leak and potentially a kernel crash later in genpd_debug_add(). The fix adds proper error handling to release resources on failure. This vulnerability affects multiple Linux kernel versions prior to specific patched releases in the 5.15 series for Ubuntu 20.04 HWE edge kernels.
