BELL-CVE-2026-31459

Affected: Alpaquita:stream: linux-lts

EUVD-2026-320963

fkie_cve-2026-31459

In the Linux kernel, the following vulnerability has been resolved:

mm/damon/sysfs: fix param_ctx leak on damon_sysfs_new_test_ctx() failure

Patch series "mm/damon/sysfs: fix memory leak and NULL dereference issues", v4.

DAMON_SYSFS can leak memory under allocation failure, and do NULL pointer dereference when a privileged user make wrong sequences of control. Fix those.

This patch (of 3):

When damon_sysfs_new_test_ctx() fails in damon_sysfs_commit_input(), param_ctx is leaked because the early return skips the cleanup at the out label. Destroy param_ctx before returning.
