with THP or base page because there is cond_resched() called for each PMD size. Although the soft lockup
was triggered by MTE, it should be not MTE specific. The other processing which takes long time in the
loop may trigger soft lockup too. So add cond_resched() for hugetlb to avoid soft lockup. (CVE-2025-40153)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.439.45 or later.
