CVE-2026-90259 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rtla package and not the rtla package as distributed by RHEL.
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.
