In the Linux kernel, the following vulnerability has been resolved:
btrfs: unlock inode and extent in caller when io_uring read extent fails
btrfs_uring_read_extent() runs only after btrfs_encoded_read() has taken
the inode shared lock and the extent lock. On failure it used to unlock
in out_fail, and a pages-array allocation failure returned -ENOMEM
without unlocking at all.
Unlock in the caller instead on all failure returns, matching the
copy_to_user() error path. The deferred -EIOCBQUEUED path still unlocks
in btrfs_uring_read_finished().
