CVE-2026-80602

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd/lbr: Fix kernel address leakage A user-only branch stack can contain branches that originate from the kernel. As a result, kernel addresses are exposed to user space even when PERFSAMPLEBRANCHUSER is requested. On AM...

CVE-2026-72237

The CVE-2026-72237 entry concerns a Linux kernel vulnerability in perf/x86/amd/brs where a user-space can observe kernel addresses due to the branch-from address not being filtered for kernel-origin branches when PERF_SAMPLE_BRANCH_USER is requested. The issue occurs on AMD processors that suppor...
