In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix reservation leak in some error paths when inserting inline extent
If we fail to allocate a path or join a transaction, we return from
__cow_file_range_inline() without freeing the reserved qgroup data,
resulting in a leak. Fix this by ensuring we call btrfs_qgroup_free_data()
in such cases.

vendor_redhat·2026-03-18·CVSS 3.3
CVE-2025-71268 [LOW] CWE-772 kernel: btrfs: fix reservation leak in some error paths when inserting inline extent
kernel: btrfs: fix reservation leak in some error paths when inserting inline extent
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix reservation leak in some error paths when inserting inline extent
If we fail to allocate a path or join a transaction, we return from
__cow_file_range_inline() without freeing the reserved qgroup data,
resulting in a leak. Fix this by ensuring we call btrfs_qgroup_free_data()
in such cases.
A resource leak was found in the Linux kernel's btrfs filesystem. In __cow_file_range_inline(), when path allocation or transaction join fails, the function returns without calling btrfs_qgroup_free_data() to release reserved qgroup data. This causes qgroup reservations to accumulate over time, potentially exhausting quota resources.
