Google: sys-kernel/lakitu-kernel-6_1, sys-kernel/lakitu-kernel-6_6: security update to 18613.75.60

medium Tenable Self-Hosted Container Security Plugin ID 472367

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: Make sure internal and UAPI
bpf_redirect flags don't overlap The bpf_redirect_info is shared between the SKB and XDP redirect paths,
and the two paths use the same numeric flag values in the ri->flags field (specifically, BPF_F_BROADCAST
== BPF_F_NEXTHOP). This means that if skb bpf_redirect_neigh() is used with a non-NULL params argument
and, subsequently, an XDP redirect is performed using the same bpf_redirect_info struct, the XDP path will
get confused and end up crashing, which syzbot managed to trigger. With the stack-allocated
bpf_redirect_info, the structure is no longer shared between the SKB and XDP paths, so the crash doesn't
happen anymore. However, different code paths using identically-numbered flag values in the same struct
field still seems like a bit of a mess, so this patch cleans that up by moving the flag definitions
together and redefining the three flags in BPF_F_REDIRECT_INTERNAL to not overlap with the flags used for
XDP. It also adds a BUILD_BUG_ON() check to make sure the overlap is not re-introduced by mistake.
(CVE-2024-50163)
