"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nperf/x86/intel: Fix crash in icl_update_topdown_event()\n\nThe perf_fuzzer found a hard-lockup crash on a RaptorLake machine:\n\n Oops: general protection fault, maybe for address 0xffff89aeceab400: 0000\n CPU: 23 UID: 0 PID: 0 Comm: swapper/23\n Tainted: [W]=WARN\n Hardware name: Dell Inc.
