Description

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.

Affected configurations

• linux linux kernel (>= 4.4 < 6.1.163) • linux linux kernel (>= 6.2 < 6.6.124) • linux linux kernel (>= 6.7 < 6.12.70) • linux linux kernel (>= 6.13 < 6.18.10) • linux linux kernel 6.19
