CVE-2024-50270

Local denial of service via DAMON arithmetic overflow

Published Nov 19, 2024 · Updated May 11, 2026

Integer overflow in Linux 6.8 through 6.11.7 and 6.12-rc1 through 6.12-rc6 allows local users to disrupt availability via DAMON feedback. damon_feed_loop_next_input() multiplies score differences and compensation values without overflow-safe ordering, then uses the wrapped result as its next input. The documented DAMON configuration path requires root permission; the bounded impact is availability loss without data exposure or modification.
