Name of the Vulnerable Software and Affected Versions Linux Kernel versions prior to v5.4.225

Description The issue is related to a potential security problem in the net/x25 component, specifically in the x25 lapb receive frame() function, where a skb leak is fixed. The actual impact and attack plausibility have not yet been proven.

Recommendations For Linux Kernel versions prior to v5.4.225, update to version v5.4.225 or later to resolve the issue. As a temporary workaround, consider restricting access to the x25 lapb receive frame() function until a patch is available.
