CVE-2026-89918

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Correctly handle end of VA space TLBI invalidation Our TLB invalidation by VA code is based on comparing two ranges, one defined by the TLB, and one defined by the TLBI instruction. Each range is defined by a start an...

CVE-2026-89911

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Correctly cap TLBI Range to the architural limit TLB Invalidation by Range has a fairly powerful way of encoding pretty large ranges in a small number of bits. This range can be based on an arbitrary VA, which means i...

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...
