high Tenable Cloud Security Plugin ID 467043

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: security/keys: fix missed RCU read
section on lookup Nicholas Carlini reports that the keyring code calls assoc_array_find() in
find_key_to_update() without holding the RCU read lock, while the assoc_array_gc() code really is designed
around removing the node from the tree and then freeing it after an RCU grace-period. The regular key
handling doesn't see this because holding the keyring semaphore hides any lifetime issues, but the
persistent key handling uses a different model. Instead of extending the keyring locking, just do the
simple RCU locking that the assoc_array was designed for. (CVE-2026-64015)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.675.2 or later.
