high Tenable Cloud Security Plugin ID 466108

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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 GENL_ADMIN_PERM; DONE has no privilege
check at all. The fd-lookup in handshake_nl_done_doit() only confirms that some pending handshake request
exists for the supplied sockfd; it does not authenticate the sender. An unprivileged process that guesses
or observes a valid sockfd can therefore submit a DONE with HANDSHAKE_A_DONE_STATUS == 0, leaving the
kernel consumer to proceed as if the handshake succeeded. A non-zero status on a forged DONE tears down a
legitimate in-flight handshake before tlshd can report its real result. (CVE-2026-74270)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.731.2 or later.
