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 struct_ops registration
that uses module ptr and the module btf_id is missing There is a UAF report in the bpf_struct_ops when
CONFIG_MODULES=n. In particular, the report is on tcp_congestion_ops that has a "struct module *owner"
member. For struct_ops that has a "struct module *owner" member, it can be extended either by the regular
kernel module or by the bpf_struct_ops. bpf_try_module_get() will be used to do the refcounting and
different refcount is done based on the owner pointer. When CONFIG_MODULES=n, the btf_id of the "struct
module" is missing: WARN: resolve_btfids: unresolved symbol module Thus, the bpf_try_module_get() cannot
do the correct refcounting. Not all subsystem's struct_ops requires the "struct module *owner" member.
e.g. the recent sched_ext_ops. This patch is to disable bpf_struct_ops registration if the struct_ops has
the "struct module *" member and the "struct module" btf_id is missing. The btf_type_is_fwd() helper is
moved to the btf.h header file for this test. This has happened since the beginning of bpf_struct_ops
which has gone through many changes. The Fixes tag is set to a recent commit that this patch can apply
cleanly. Considering CONFIG_MODULES=n is not common and the age of the issue, targeting for bpf-next also.
(CVE-2024-58060)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19738.0.0 or later.
