CVE-2026-80891

CVE-2026-80891 affects the Linux kernel 's KVM s390 PCI subsystem. The vulnerability arises when the AIBV (Adaptive Interrupt Bit Vector) size—derived from the NOI and AIBVO—exceeds a single page boundary, making it impossible to safely pin the guest page. Additionally, the AISB (Adaptive Interru...

CVE-2026-80876

CVE-2026-80876 affects the Linux kernel ring-buffer subsystem on architectures where RB_FORCE_8BYTE_ALIGNMENT is true (observed on riscv64 with CONFIG_HAVE_64BIT_ALIGNED_ACCESS=y). The root cause is a mismatch in length calculation: rb_calculate_event_length() unconditionally reserves sizeof(even...
