high Tenable Self-Hosted Container Security Plugin ID 472617

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: kprobes: Protect kprobe_blacklist with
RCU __within_kprobe_blacklist() traverses kprobe_blacklist without holding kprobe_mutex. When a module is
unloaded, kprobe_remove_area_blacklist() removes blacklist entries and immediately frees them with
kfree(). A concurrent call to within_kprobe_blacklist() can therefore dereference freed memory.
Furthermore, within_kprobe_blacklist() can be called in atomic or non-preemptible contexts where the
sleeping kprobe_mutex cannot be taken. Protect kprobe_blacklist with RCU. Use guard(rcu)() and
list_for_each_entry_rcu() for traversal, list_add_tail_rcu() for insertions, list_del_rcu() for deletions,
and kfree_rcu() to reclaim entries safely after a grace period. (CVE-2026-89988)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.624.2 or later.
