CVE-2026-53296

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the mailbox-test component where channels are not freed during a probe error. This failure to release resources leads to a memory leak and creates Use-After-Free (UAF) scenarios, as the client structure is removed due to its allocation with devm while the channels remain active.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
