CVE-2026-31653

Summary : CVE-2026-31653 impacts the Linux kernel DAMON subsystem (DAMON_SYSFS). When a monitored process terminates before damon_call() runs, a dynamically allocated repeat_call_control is not deallocated, causing a memory leak. The connected sources document the root cause and confirm the fix: ...

CVE-2026-31652

The CVE-2026-31652 issue is in the Linux kernel’s DAMON feature. When damon_stat_start() allocates damon_ctx and damon_call() subsequently fails, the damon_ctx object is not deallocated, causing a memory leak if DAMON is re-enabled. The leak is not resolved by deallocating after damon_call() fail...

kernel: Linux kernel: Local denial of service and memory leak in DAMON sysfs via setup failure

A flaw was found in the Linux kernel's Data Access MONitor DAMON sysfs interface. A local attacker, typically a privileged user, could exploit a cleanup bug during DAMON context setup. If the setup fails after the attrs directory is created, stale sysfs directories are left behind. This can lead ...
