high Tenable Self-Hosted Container Security Plugin ID 469275

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,fork: wipe ->bpf_storage before
bailouts that access it Currently, copy_process() can bail out to free_task() before p->bpf_storage has
been initialized, with this call graph (shown here for the !CONFIG_MEMCG case): copy_process
dup_task_struct arch_dup_task_struct [copies the entire task_struct, including ->bpf_storage member]
[RLIMIT_NPROC check fails] delayed_free_task free_task bpf_task_storage_free
rcu_dereference(task->bpf_storage) bpf_local_storage_destroy In this case, the nascent task's
->bpf_storage member that bpf_local_storage_destroy() operates on is a plain copy of the parent's
->bpf_storage pointer, not a real initialized pointer. This leads to badness (kernel hangs, UAF). This is
reachable as long as the process calling fork() has been inserted into a task storage map.
(CVE-2026-72110)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.655.6 or later.
