Subject: [BUG] arm_pmuv3: Invalid PMEV index and lockup triggered via perf_event_open
Date: Wed, 23 Jul 2025 20:36:33 +0900 [thread overview]
Message-ID: <b4baa935-5ddd-42ce-add4-811ed74c2be7@kzalloc.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 1316 bytes --]
Hi,
While testing the 6.16.0-rc2 kernel on an AArch64 QEMU environment on the, I
encountered a warning followed by a soft lockup that seems to be triggered by a
bad PMU index access and a circular locking dependency. This was observed during
perf_event_open() execution triggered by syzkaller.
Here's a summary of the issue:
---
WARNING: possible circular locking dependency detected
Chain exists of:
console_owner --> &rq->__lock --> &ctx->lock
Possible unsafe locking scenario:
CPU0 CPU1
---- ----
lock(&ctx->lock);
lock(&rq->__lock);
lock(&ctx->lock);
lock(console_owner);
---
And this happens while the system is handling a perf event overflow and trying to
update PMU counters or start/stop events.
Environment:
- Kernel: v6.16.0-rc2
- Platform: QEMU aarch64 (KVM enabled Radxa's Orion6 platform.)
- Arm64 PMU focused kernel fuzzing with perf_event_open, based on syzkaller
- No additional modules loaded
The issue is reproducible, and for detailed reproduction steps, please refer to
Link: https://lore.kernel.org/lkml/20250723104359.364547-5-ysk@kzalloc.com/
I’ve attached the original log from the lockup as well as the decoded version.
Best regards,
Yunseong Kim
