Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.85.5

medium Tenable Self-Hosted Container Security Plugin ID 451624

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: tls: fix NULL deref on
tls_sw_splice_eof() with empty record syzkaller discovered that if tls_sw_splice_eof() is executed as part
of sendfile() when the plaintext/ciphertext sk_msg are empty, the send path gets confused because the
empty ciphertext buffer does not have enough space for the encryption overhead. This causes
tls_push_record() to go on the `split = true` path (which is only supposed to be used when interacting
with an attached BPF program), and then get further confused and hit the tls_merge_open_record() path,
which then assumes that there must be at least one populated buffer element, leading to a NULL deref. It
is possible to have empty plaintext/ciphertext buffers if we previously bailed from
tls_sw_sendmsg_locked() via the tls_trim_both_msgs() path. tls_sw_push_pending_record() already handles
this case correctly; let's do the same check in tls_sw_splice_eof(). (CVE-2023-52767)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18244.85.5 or later.
