CVE-2026-74727

A flaw was found in the Linux kernel's ovpn module. A race condition can occur when an OpenVPN ovpn peer is removed concurrently while the system attempts to rehash it. This can lead to the peer being re-inserted into internal tables after it has been logically removed, creating a Use-After-Free...

CVE-2026-74727

In the Linux kernel, the following vulnerability has been resolved: ovpn: skip rehash for peers already removed from byid ovpnnlpeersetdoit resolves the target peer via ovpnpeergetbyid before taking ovpn-lock. In the window between the lookup which only takes a refcount and the subsequent...

CVE-2026-74586

In the Linux kernel, the following vulnerability has been resolved: sctp: clear newtransport when removing a peer sctpprocessasconfparam stores a newly added peer transport in asoc-newtransport. After all parameters in the ASCONF chunk have been processed, sctpsfdoasconf uses this pointer to send...

CVE-2026-74727

A race condition in the Linux kernel's ovpn module (in-kernel OpenVPN) causes a Use-After-Free . When a peer is removed concurrently (via OVPN_CMD_PEER_DEL, keepalive expiry, or socket teardown) while ovpn_nl_peer_set_doit() or the float path (ovpn_peer_endpoints_update()) holds only a refcount, ...

CVE-2026-64045

CVE-2026-64045 (Linux kernel, ovpn tcp close race) : The vulnerability stems from ovpn_tcp_close() loading the ovpn_socket pointer under RCU read-lock, then using sock->peer after releasing the lock, while ovpn_socket_release() may detach the socket concurrently. The fix tightens the pattern b...
