CVE-2025-37807

CVE-2025-37807 is a Linux kernel issue in the BPF percpu hashmap path where a percpu pointer is stored at an 8-byte aligned location only if the key_size rounds up to 8; otherwise a 4-byte aligned location is used, causing kmemleak to miss the pointer and report a leak. The root cause is an align...
