CVE-2025-39916: Debian Linux

Medium severity, CVSS 5.5. EPSS: 0.1% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 11.0 only
• Linux Linux Kernel: from 6.0.12, before 6.1.153 (fixed in 6.1.153); from 6.2, before 6.6.107 (fixed in 6.6.107); from 6.7, before 6.12.48 (fixed in 6.12.48); from 6.13, before 6.16.8 (fixed in 6.16.8); version 6.17 only
