Echo: linux: security update to 6.12.95-1

medium Tenable Self-Hosted Container Security Plugin ID 462823

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 linux library and its related packages to version 6.12.95-1 or later.
