Description OSIDB Bzimport 2025-01-22 05:46:07 UTC

The UnMountPodLogs and LinkContainerLogs functions in CRI-O do not properly validate the emptyDirVolName parameter, making them vulnerable to a path traversal attack. An attacker can exploit this to unmount arbitrary paths on the host system, potentially causing denial of service or compromising system integrity.
