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 BPF_PSEUDO_FUNC reference
to the main program fixups.c:jit_subprogs() rewrites BPF_PSEUDO_FUNC loads to contain real function
addresses. This function is invoked from bpf_jit_subprogs() only when env->subprog_cnt > 1. Meaning that
for any program like below: int main(void *ctx) { void *ptr = main; ... bpf_timer_set_callback(..., ptr);
... } The 'ptr' won't be ever converted to contain an address. In combination with e.g.
bpf_timer_set_callback() this would lead to a function call at a bogus address. Instead of complicating
the implementation, just assume that no useful program needs main to be a sync or async callback and
reject BPF_PSEUDO_FUNC loads for the main subprogram. (CVE-2026-98075)

Solution

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