In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix qgroup reserve leaks in cow_file_range
In the buffered write path, the dirty page owns the qgroup reserve until
it creates an ordered_extent.
Therefore, any errors that occur before the ordered_extent is created
must free that reservation, or else the space is leaked. The fstest
generic/475 exercises various IO error paths, and is able to trigger
errors in cow_file_range where we fail to get to allocating the ordered
extent. Note that because we *do* clear delalloc, we are likely to
remove the inode from the delalloc list, so the inodes/pages to not have
invalidate/launder called on them in the commit abort path.
This results in failures at the unmount stage of the test that look like:
BTRFS: error (device dm-8 state EA) in cleanup_transaction:2018: errno=-5 IO failure
BTRFS: error (device dm-8 state EA) in btrfs_replace_file_extents:2416: errno=-5 IO failure
BTRFS warning (device dm-8 state EA): qgroup 0/5 has unreleased space, type 0 rsv 28672

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
