CVE-2026-31457

A flaw was found in the Linux kernel. A local user can exploit this vulnerability by setting the nrcontexts parameter to zero via the DAMON sysfs interface while DAMON Data Access MONitor is active. This improper input validation leads to a NULL pointer dereference, which can cause a system crash...

CVE-2026-31459

CVE-2026-31459 affects the Linux kernel DAMON_SYSFS path. The vulnerability is a memory leak: when damon_sysfs_new_test_ctx() fails inside damon_sysfs_commit_input(), param_ctx is leaked because the cleanup at the out label is skipped. The patch series “mm/damon/sysfs: fix memory leak and NULL de...

CVE-2026-31457

The CVE-2026-31457 entry describes a Linux kernel vulnerability in DAMON (mm/damon/sysfs) where damon_sysfs_repeat_call_fn() dereferences contexts_arr[0] when nr_contexts is set to 0 via sysfs, due to a missing check on contexts->nr. This can occur while DAMON is running and cause a NULL point...

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 ...
