CVE-2026-64117 wifi: mac80211: capture fast-RX rate before mesh reuses skb->cb

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: capture fast-RX rate before mesh reuses skb-cb ieee80211invokefastrx reads RX status through IEEE80211SKBRXCBskb, which aliases the same skb-cb storage that ieee80211rxmeshdata reuses as IEEE80211TXINFO. In the...

CVE-2026-64044

Concrete details confirm CVE-2026-64044 fix in the Linux kernel’s OpenVPN peer handling. The error path in ovpn_nl_peer_new_doit() previously called ovpn_peer_release() directly instead of ovpn_peer_put(), bypassing the kref, risking use-after-free when a caller holds a ref during an in-flight op...

CVE-2026-64044 ovpn: respect peer refcount in CMD_NEW_PEER error path

In the Linux kernel, the following vulnerability has been resolved: ovpn: respect peer refcount in CMDNEWPEER error path ovpnnlpeernewdoit's error path calls ovpnpeerrelease directly rather than ovpnpeerput, bypassing the kref. The accompanying comment "peer was not yet hashed, thus it is not use...

CVE-2026-64024

CVE-2026-64024 concerns a Linux kernel issue where a per-CPU tcp_tw_isn leak could enable ISN prediction. The root cause was that TIME_WAIT-derived ISNs were stored in a per-CPU variable and could be consumed by a subsequent SYN if a packet was dropped along several paths (e.g., min_ttl/min_hop, ...

CVE-2026-64010

CVE-2026-64010 involves a use-after-free in the Linux NFC LLCP stack. The race occurs when nfc_llcp_recv_cc() moves a socket from the connecting_sockets list to the sockets list without holding the socket lock, risking linking a freed socket if llcp_sock_release() runs concurrently. The mitigatio...

CVE-2026-64011

The CVE-2026-64011 issue affects the Linux kernel NFC LLCP path: llcp_sock_release() unlinks a socket from the local sockets list unconditionally, but if the socket is still in the connecting state it resides on the connecting list. The fix adds a state check and unlinks from the correct list, ad...

CVE-2026-64007

The CVE concerns the Linux kernel netfilter synproxy path. In synproxy_tstamp_adjust, the code rewrites the TCP timestamp in place and then updates the TCP checksum via inet_proto_csum_replace4() on a caller-supplied tcphdr pointer. Between retrieving the pointer (via skb_header_pointer) and use,...
