CVE-2026-80852

CVE-2026-80852 is an out-of-bounds write in the Linux kernel's TLS device offload path (net/tls/tls_device.c). The root cause is that tls_push_data() skips its fragment-count check on an early MSG_MORE break, allowing num_frags to exceed MAX_SKB_FRAGS (17) when splice(SPLICE_F_MORE) calls are iss...

In the Linux kernel, the following vulnerability has been resolved: tls: device: fix out-of-bounds write in tlsappendfrag Found with syzkaller and a local syzbot instance running on top of a netdevsim TLS offload emulation; tlsdevice.c is otherwise only reachable on a machine with a NIC that...

EUVD-2026-71301

In the Linux kernel, the following vulnerability has been resolved: gtp: serialize PDP context updates PDP contexts can be deleted through GTPCMDDELPDP or while the GTP network device is being unregistered. The latter is serialized by RTNL, but the generic-netlink delete path only holds RCU...

CVE-2026-80851

CVE-2026-80851 is a race condition in the Linux kernel's GTP (GPRS Tunnelling Protocol) module . PDP contexts could be double-deleted when the generic-netlink delete path (GTP_CMD_DELPDP) and GTP device unregistration (RTM_DELLINK) ran concurrently, since the former holds only RCU while the latte...

CVE-2026-80851 gtp: serialize PDP context updates

In the Linux kernel, the following vulnerability has been resolved: gtp: serialize PDP context updates PDP contexts can be deleted through GTPCMDDELPDP or while the GTP network device is being unregistered. The latter is serialized by RTNL, but the generic-netlink delete path only holds RCU...

CVE-2026-80850 tcp: fix AO info use-after-free in tcp_ao_connect_init()

In the Linux kernel, the following vulnerability has been resolved: tcp: fix AO info use-after-free in tcpaoconnectinit tcpv4connect adds a SYN-SENT socket to the ehash before calling tcpconnect. If TCP-AO is configured, tcpconnect first verifies that a key matches the peer and the bound device's...

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...

In the Linux kernel, the following vulnerability has been resolved: net/tcp-ao: fix use-after-free of currentkey on reconnect to another peer tcpinboundaohash is called before bhlocksocknested is taken, with only rcureadlock held. On the fast path for established sockets, if the rnextkeyid sent b...

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...

CVE-2026-80848

A use-after-free (UAF) vulnerability in the Linux kernel's xfrm/espintcp subsystem was reported by ZDI . The race condition occurs during socket close: espintcp_close() frees emsg->skb via kfree_skb() without holding a socket lock, while concurrently the xfrm_trans_reinject work queue invokes ...

In the Linux kernel, the following vulnerability has been resolved: tcp: clamp route advmss to TCPMINMSS tcpselectinitialwindow assumes that callers never pass an MSS smaller than 1, but route-derived advmss values can violate that assumption. A too-small explicit RTAXADVMSS is one way to get...

CVE-2026-80847

CVE-2026-80847 affects the Linux kernel TCP subsystem. The root cause is a divide-by-zero in tcp_select_initial_window(), which assumes the advertised MSS (advmss) is at least 1. Route-derived advmss values can violate this assumption—either via an explicit too-small RTAX_ADVMSS or through the de...
