CVE-2026-89984: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel: Fix kernel address leakages in LBR stack Before Arch LBR gained CPL filtering support, a user-only branch stack could still contain kernel addresses. As a result, kernel branch records may be exposed to user space...

CVE-2026-80602 perf/x86/amd/lbr: Fix kernel address leakage

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...

Xen Arm-Based CPU Speculation past the ERET Instruction (XSA-312)

According to its self-reported version number, the Xen hypervisor installed on the remote host is affected by a speculative memory accesses vulnerability. Some CPUs can speculate past an ERET instruction and potentially perform speculative accesses to memory before processing the exception return...

arm: a CPU may speculate past the ERET instruction

ISSUE DESCRIPTION Some CPUs can speculate past an ERET instruction and potentially perform speculative accesses to memory before processing the exception return. Since the register state is often controlled by lower privilege level i.e guest kernel/userspace at the point of the ERET, this could...
