Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.236.26

medium Tenable Self-Hosted Container Security Plugin ID 451379

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: Zero former ARG_PTR_TO_{LONG,INT}
args in case of error For all non-tracing helpers which formerly had ARG_PTR_TO_{LONG,INT} as input
arguments, zero the value for the case of an error as otherwise it could leak memory. For tracing, it is
not needed given CAP_PERFMON can already read all kernel memory anyway hence bpf_get_func_arg() and
bpf_get_func_ret() is skipped in here. Also, the MTU helpers mtu_len pointer value is being written but
also read. Technically, the MEM_UNINIT should not be there in order to always force init. Removing
MEM_UNINIT needs more verifier rework though: MEM_UNINIT right now implies two things actually: i) write
into memory, ii) memory does not have to be initialized. If we lift MEM_UNINIT, it then becomes: i) read
into memory, ii) memory must be initialized. This means that for bpf_*_check_mtu() we're readding the
issue we're trying to fix, that is, it would then be able to write back into things like .rodata BPF maps.
Follow-up work will rework the MEM_UNINIT semantics such that the intent can be better expressed. For now
just clear the *mtu_len on error path which can be lifted later again. (CVE-2024-47728)
