CVE-2022-49565

CVE-2022-49565 concerns the Linux kernel, specifically perf/x86/intel/lbr, where unchecked MSR writes (WRMSR to 0x689) can occur due to an absent TSX quirk application when accessing LBR data. The issue manifests on systems with LBR_FORMAT_EIP_FLAGS2 and, if TSX is disabled, requires a quirk to a...
