medium Tenable Self-Hosted Container Security Plugin ID 469049

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: bpf: Reject sleepable kprobe_multi
programs at attach time kprobe.multi programs run in atomic/RCU context and cannot sleep. However,
bpf_kprobe_multi_link_attach() did not validate whether the program being attached had the sleepable flag
set, allowing sleepable helpers such as bpf_copy_from_user() to be invoked from a non-sleepable context.
This causes a "sleeping function called from invalid context" splat: BUG: sleeping function called from
invalid context at ./include/linux/uaccess.h:169 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid:
1787, name: sudo preempt_count: 1, expected: 0 RCU nest depth: 2, expected: 0 Fix this by rejecting
sleepable programs early in bpf_kprobe_multi_link_attach(), before any further processing.
(CVE-2026-43010)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.532.25 or later.
