CVE-2026-89918

CVE-2026-89918 affects the Linux kernel KVM arm64 subsystem. The root cause is a flaw in the TLB invalidation (TLBI) by virtual address range: when the TLBI instruction's range reaches the end of the TTBR1 VA space , the expression base + size wraps around to 0, causing the range comparison to fa...

CVE-2026-89911

CVE-2026-89911 affects the KVM arm64 subsystem of the Linux kernel. The root cause is an integer overflow in the handling of TLB Invalidation by Range (TLBI) : because the TLBI range can be encoded with a large value based on an arbitrary virtual address, a guest can trigger an overflow if the hy...
