CVE-2026-74645

CVE-2026-74645 is a division-by-zero vulnerability in the Linux kernel's DAMON_LRU_SORT module. When a user sets the active_mem_bp parameter to 10002 , the cold memory scheme's quota goal target value becomes zero, causing damos_quota_score() to trigger a kernel oops (divide error). The fix retur...
