CVE-2025-68355

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

bpf: Fix exclusive map memory leak

When excl_prog_hash is 0 and excl_prog_hash_size is non-zero, the map also needs to be freed. Otherwise, the map memory will not be reclaimed, just like the memory leak problem reported by syzbot [1].
