CVE-2026-74270 handshake: Require admin permission for DONE command

In the Linux kernel, the following vulnerability has been resolved: handshake: Require admin permission for DONE command ACCEPT and DONE are the two downcalls of the handshake genl family, both intended for use by the trusted handshake agent tlshd. ACCEPT already requires GENLADMINPERM; DONE has ...

CVE-2026-74270

The CVE-2026-74270 vulnerability affects the Linux kernel handling of the handshake genl family. The DONE downcall previously performed no privilege check, allowing an unprivileged process that could observe or guess a valid socket to submit DONE with HANDSHAKE_A_DONE_STATUS == 0, causing the ker...

CVE-2026-72222

The CVE-2026-72222 entry corresponds to a Linux kernel vulnerability in the sunrpc TLS handshake path. The issue arises from races where an in-flight async TLS handshake callback can write through a freed svc_sock, due to the embedding svc_sock being container_of() referenced after tls_handshake_...
