CVE-2026-80862

This Linux kernel vulnerability affects the nvme-tcp subsystem. The page_frag_cache is used to preallocate PDU buffers for preallocated block device requests, but since block devices are created in parallel threads, the cache is accessed in a thread-unsafe manner. This leads to incorrect refcount...

CVE-2026-80850

CVE-2026-80850 is a use-after-free in the Linux kernel's TCP-AO implementation. During tcp_v4_connect(), a race exists between initial key validation and the later L3-master resolution in tcp_ao_connect_init(). If the bound network device is detached from its VRF in that window, the only AO key i...

CVE-2026-80849

This vulnerability affects the Linux kernel's TCP Address Obfuscation (TCP-AO) subsystem. The root cause is a use-after-free of current_key triggered when a socket is disconnected and connect() is called for a different peer. Because tcp_inbound_ao_hash() runs with only rcu_read_lock() held, a so...
