CVE-2026-74643

CVE-2026-74643 is a division-by-zero vulnerability in the Linux kernel affecting the DAMON_SAMPLE_MTIER and DAMON_LRU_SORT modules. The root cause is that damos_quota_score() does not guard against a zero target_value, which users can set via the node0_mem_{used,free}_bp sysfs parameters. Trigger...
