GHSA-54P7-C699-6P2V

Vulnerability from github – Published: 2025-10-01 09:30 – Updated: 2026-01-16 21:30

Details

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

mm/damon/reclaim: avoid divide-by-zero in damon_reclaim_apply_parameters()

When creating a new scheme of DAMON_RECLAIM, the calculation of 'min_age_region' uses 'aggr_interval' as the divisor, which may lead to division-by-zero errors. Fix it by directly returning -EINVAL when such a case occurs.

Severity

5.5 (Medium)
