CVE-2025-38202

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

Description: A vulnerability in the Linux kernel has been resolved. The issue is related to the bpf map lookup percpu elem() helper function, which is available for sleepable BPF programs. When BPF JIT is disabled or under a 32-bit host, bpf map lookup percpu elem() will not be inlined, triggering a warning because the BPF program only holds the rcu read lock trace lock. To address this, a check for rcu read lock trace held() has been added to bpf map lookup percpu elem().

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