CVE-2026-90259 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python3-perf package and not the python3-perf package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
btrfs: qgroup: fix a wrong length calculation in qgroup_free_reserved_data()
In that function, we round down the start position and round up the ending position.
But during the calculation of @len, we use "round_up(start + len, sectorsize)", which is the rounded up end position, not the rounded up length.
Which results a much larger length, and later we are still using "start + len", which is completely incorrect.
Fix it by declaring a local @aligned_start and @aligned_len and use them instead.
