CVE-2026-89928
CVE-2026-89928 is a slab use-after-free in the Linux kernel's KVM x86/mmu subsystem. The root cause is a race condition in the lockless reverse-mapping (rmap) walk: kvm_rmap_age_gfn_range() ignores the value returned by kvm_rmap_lock_readonly() and instead re-reads the rmap head via rmap_get_firs...
CVE-2026-89927 KVM: x86: hyper-v: Clamp stimer deadline to avoid livelock
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: hyper-v: Clamp stimer deadline to avoid livelock Fix an issue where userspace or the guest can program an Hyper-V synthetic timer to have a deadline in the past via integer overflow, preventing the CPU from making...

CVE-2026-89927
CVE-2026-89927 is an integer overflow vulnerability in the Linux kernel's KVM x86 Hyper-V synthetic timer (stimer) emulation. When the STIMER COUNT MSR is programmed with a value close to U64_MAX , the deadline calculation overflows, producing a deadline in the past. This causes the hrtimer to fi...

EUVD-2026-80518
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-2026-89918
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...
