CVE-2022-50300

CVE-2022-50300 affects the Linux kernel's btrfs code, where an extent_map use-after-free can occur in read_one_chunk when handling a missing device and the degraded mount option is absent. The root cause is freeing the extent_map before storing the error code, despite the structure being referenc...
