CVE-2025-68378

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

Description The Linux kernel contains a flaw in the bpf get stackid() function related to a stackmap overflow check. This issue, identified by Syzkaller, can lead to a KASAN slab-out-of-bounds write when copying stack trace data. The problem arises when the number of stack entries in a perf trace exceeds the capacity of the stack map bucket, resulting in a write beyond the allocated memory region within the bucket’s data array.

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