high Tenable Cloud Security Plugin ID 468999

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: Preserve unique-field state
across nested structs btf_find_struct_field() initializes a fresh seen mask for every recursive descent.
Unique special fields in different levels of the same aggregate therefore do not see one another. The
duplicate fields can reach btf_parse_fields(), where they trigger an invariant WARN_ON_ONCE(). A crafted
user BTF can consequently trigger the warning before map creation checks capabilities. Initialize the seen
mask once in btf_find_field() and pass the same pointer through struct, datasec, and nested-struct walks.
This gives the entire field traversal one shared uniqueness state. (CVE-2026-92515)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
