CVE-2026-89928

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Consume the locked rmap value in the lockless rmap walk kvmrmaplock deliberately elides the rmap lock when it observes an empty rmap. In that case kvmrmaplockreadonly also re-enables preemption and returns zero, so...

CVE-2026-89984

This vulnerability affects the Linux kernel 's perf/x86/intel subsystem. Before Arch LBR gained CPL filtering support, intel_pmu_lbr_filter() did not fully validate the privilege level of sampled entries. While it filtered some mismatches based on branch type and the destination address, it faile...
