high Tenable Self-Hosted Container Security Plugin ID 475421

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: Mark faultable stack helpers as
sleepable The faultable variants of bpf_get_stack() and bpf_get_task_stack() pass may_fault=true into the
common stack collection code. Resolving user-space build IDs may then call build_id_parse_file() and block
on filesystem reads. Neither helper prototype sets might_sleep. Since prototype selection uses the
sleepability of the whole program, the verifier can still allow these helpers from a non-sleepable region
within that program, such as an explicit RCU or preemption-disabled region. The task-stack helper can also
be called from a non-sleepable timer callback of a sleepable program. Mark both faultable prototypes as
sleepable. The existing helper context check then rejects these calls while continuing to allow them in
genuinely sleepable contexts. (CVE-2026-98045)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19999.44.106 or later.
