Answer in brief
CVE-2025-38322 records a Medium severity (CVSS 5.5) vulnerability in perf/x86/intel: Fix crash in icl_update_topdown_event(). The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic), Siemens/SIMATIC CN 4100 (generic), Siemens/SIMATIC S7-1500 CPU 1518-4 PN/DP MFP (generic) and additional mapped packages. Check affected ranges and fixed versions before updating.

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel: Fix crash in icl_update_topdown_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.

The icl_update_topdown_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 is_topdown_event() function is mistakenly used to replace the is_topdown_count() call to check if the topdown functions for the perf metrics feature should be invoked. Fix it.
