EUVD-2026-80528

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Consume the locked rmap value in the lockless rmap walk kvmrmaplock deliberately elides the rmap lock when it observes an empty rmap. In that case kvmrmaplockreadonly also re-enables preemption and returns zero, so...

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-2026-89771

This Linux kernel race condition affects the trace ring buffer resize mechanism. The field trace_buffer::subbuf_size is read locklessly in ring_buffer_read_page() and ring_buffer_read_start() while it can be concurrently modified by ring_buffer_subbuf_order_set(). According to Red Hat, this can a...

CVE-2026-89705

CVE-2026-89705 affects the Linux kernel NFS daemon (nfsd) . The nfsd_dispatch() function uses a sequence-lock-like protocol via rq_status_counter, setting it to an odd value when a request is decoded and restoring it to even after processing. However, the cache-hit, drop, and encode-error exit pa...
