CVE-2026-64256

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

xfs: don't wrap around quota ids in dqiterate

LOLLM noticed that q_id is an unsigned 32-bit variable. If it happens to be set to XFS_DQ_ID_MAX due to a filesystem that actually has a dquot for ID_MAX, then this addition will truncate to zero and the iteration starts over. Fix this by casting to u64.
