CVE-2026-64256
CVE-2026-64256 affects the Linux kernel/XFS: a dqiterate quota-id loop uses an unsigned 32-bit q_id, which can wrap when reaching XFS_DQ_ID_MAX, causing the iteration to restart. The fix casts to 64-bit (u64) to prevent truncation. Exploitation details are not provided in the supplied documents. ...
