Title
perf: Ensure swevent hrtimer is properly destroyed
Summary
In the Linux kernel, the following vulnerability has been resolved: perf: Ensure swevent hrtimer is properly destroyed With the change to hrtimer_try_to_cancel() in perf_swevent_cancel_hrtimer() it appears possible for the hrtimer to still be active by the time the event gets freed. Make sure the event does a full hrtimer_cancel() on the free path by installing a perf_event::destroy handler.
Severity

There is no network, adjacent, or physical attack path.\nAC:L - The attacker controls event creation, timer activation, and fd close/release, and can repeat the sequence to hit the hrtimer lifetime race. No unusual external condition beyond normal perf availability is required.\nPR:L - A basic local user can create a per-task hrtimer-backed perf event for itself, for example with exclude_kernel=1, without needing CPU-wide or kernel-profiling privileges. More privileged modes exist, but they are not required for this vulnerable path.\nUI:N - Exploitation does not require any victim action after the attacker runs local code. The attacker can open and close the perf event directly.\nS:U - The impact remains within the kernel security authority of the same system. This is a standard local kernel memory corruption/privilege escalation scenario, not a VM escape or cross-scope boundary violation.\nC:H - The bug leaves an hrtimer callback referencing a freed perf_event object, creating a use-after-free condition. Under conservative kernel UAF scoring, this can plausibly be leveraged for kernel memory disclosure.\nI:H - The dangling callback dereferences the freed object and can reach function-pointer-bearing perf_event state such as PMU and overflow handling paths. Treating the UAF conservatively, this is plausibly exploitable for kernel control-flow or arbitrary write effects.\nA:H - Even without full exploitation, the stale hrtimer callback can dereference freed or reused kernel memory and crash or panic the system. The availability impact is therefore high."
