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

medium Tenable Self-Hosted Container Security Plugin ID 450944

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: gso: fix udp gso fraglist segmentation
after pull from frag_list Detect gso fraglist skbs with corrupted geometry (see below) and pass these to
skb_segment instead of skb_segment_list, as the first can segment them correctly. Valid SKB_GSO_FRAGLIST
skbs - consist of two or more segments - the head_skb holds the protocol headers plus first gso_size - one
or more frag_list skbs hold exactly one segment - all but the last must be gso_size Optional datapath
hooks such as NAT and BPF (bpf_skb_pull_data) can modify these skbs, breaking these invariants. In extreme
cases they pull all data into skb linear. For UDP, this causes a NULL ptr deref in
__udpv4_gso_segment_list_csum at udp_hdr(seg->next)->dest. Detect invalid geometry due to pull, by
checking head_skb size. Don't just drop, as this may blackhole a destination. Convert to be able to pass
to regular skb_segment. (CVE-2024-49978)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18244.236.26 or later.
