CVE-2026-46121

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 7.0.11-1.1

Description A use-after-free issue exists in the DAMON sysfs interface. Direct reads and writes of the memcg path and path files can race, as the write operation deallocates the buffer pointed to by memcg path without proper locking. While reads for parameters committing are protected by damon sysfs lock, user-driven direct reads and writes are not, allowing a reader to access a buffer that has already been freed when separate open files are used for reading and writing.

Recommendations Update to version 7.0.11-1.1.
