CVE-2026-80682

In the Linux kernel, the following vulnerability has been resolved: riscv/mm: use physical alignment for vmemmapstartpfn RISC-V computes vmemmapstartpfn by rounding physrambase down to VMEMMAPADDRALIGN. That alignment must therefore be expressed in the physical-address domain. Commit 476849b0fba4...

UBUNTU-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-2026-80602

CVE-2026-80602 is an information disclosure vulnerability in the Linux kernel 's perf/x86/amd/lbr subsystem. On AMD processors supporting X86_FEATURE_AMD_LBR_V2 , the hardware branch filter only validates the privilege level of the branch target , not the branch from address. As a result, SYSRET/...
