UBUNTU-CVE-2025-21853: Medium severity ubuntu/linux-hwe-edge vulnerability

Published Mar 12, 2025
·
Updated

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 for entire duration of all the mm and VMA manipulations, which is completely unnecessary. This can potentially also lead to deadlocks, as reported by syzbot in [0]. So, instead, hold freezemutex only during writeability checks, bump (proactively) "write active" count for the map, unlock the mutex and proceed with mmap logic. And only if something went wrong during mmap logic, then undo that "write active" counter increment. [0] https://lore.kernel.org/bpf/678dcbc9.050a0220.303755.0066.GAE@google.com/
