Description
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix extent map use-after-free when adding pages to compressed bio
At add_ra_bio_pages() we are accessing the extent map to calculate
'add_size' after we dropped our reference on the extent map, resulting
in a use-after-free. Fix this by computing 'add_size' before dropping our
extent map reference.
Affected configurations
• debian debian linux 11.0
• linux linux kernel (>= 5.16 < 6.1.108)
• linux linux kernel (>= 6.2 < 6.6.44)
• linux linux kernel (>= 6.7 < 6.10.3)
