In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix extent map use-after-free when handling missing device in read_one_chunk
Store the error code before freeing the extent_map. Though it's
reference counted structure, in that function it's the first and last
allocation so this would lead to a potential use-after-free.
The error can happen eg. when chunk is stored on a missing device and
the degraded mount option is missing.
