CVE-2025-21853 bpf: avoid holding freeze_mutex during mmap operation

In the Linux kernel, the following vulnerability has been resolved: bpf: avoid holding freezemutex during mmap operation We use map-freezemutex to prevent races between mapfreeze and memory mapping BPF map contents with writable permissions. The way we naively do this means we'll hold freezemutex...

CVE-2025-21853

CVE-2025-21853 affects the Linux kernel BPF mmap path. The issue arises from holding map->freeze_mutex for the entire duration of mmap mm/VMA manipulations when ensuring writeable map contents, which could deadlock. The fixed approach holds freeze_mutex only during writeability checks, increme...
