- Summary
- perf/x86/intel: Fix crash in icl_update_topdown_event()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/intel: Fix crash in iclupdatetopdown_event()
The perf_fuzzer found a hard-lockup crash on a RaptorLake machine:
Oops: general protection fault, maybe for address 0xffff89aeceab400: 0000 CPU: 23 UID: 0 PID: 0 Comm: swapper/23 Tainted: [W]=WARN Hardware name: Dell Inc. Precision 9660/0VJ762 RIP: 0010:nativereadpmc+0x7/0x40 Code: cc e8 8d a9 01 00 48 89 03 5b cd cc cc cc cc 0f 1f ... RSP: 000:fffb03100273de8 EFLAGS: 00010046 .... Call Trace: <TASK> iclupdatetopdownevent+0x165/0x190 ? ktimeget+0x38/0xd0 intelpmureadevent+0xf9/0x210 _perfeventread+0xf9/0x210
CPUs 16-23 are E-core CPUs that don't support the perf metrics feature. The iclupdatetopdown_event() should not be invoked on these CPUs.
It's a regression of commit:
f9bdf1f95339 ("perf/x86/intel: Avoid disable PMU if !cpuc->enabled in sample read")
The bug introduced by that commit is that the istopdownevent() function is mistakenly used to replace the istopdowncount() call to check if the topdown functions for the perf metrics feature should be invoked.
Fix it.
