Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.151.9

medium Tenable Self-Hosted Container Security Plugin ID 450644

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 missing memory barrier in
tls_init In tls_init(), a write memory barrier is missing, and store-store reordering may cause NULL
dereference in tls_{setsockopt,getsockopt}. CPU0 CPU1 ----- ----- // In tls_init() // In tls_ctx_create()
ctx = kzalloc() ctx->sk_proto = READ_ONCE(sk->sk_prot) -(1) // In update_sk_prot() WRITE_ONCE(sk->sk_prot,
tls_prots) -(2) // In sock_common_setsockopt() READ_ONCE(sk->sk_prot)->setsockopt() // In
tls_{setsockopt,getsockopt}() ctx->sk_proto->setsockopt() -(3) In the above scenario, when (1) and (2) are
reordered, (3) can observe the NULL value of ctx->sk_proto, causing NULL dereference. To fix it, we rely
on rcu_assign_pointer() which implies the release barrier semantic. By moving rcu_assign_pointer() after
ctx->sk_proto is initialized, we can ensure that ctx->sk_proto are visible when changing sk->sk_prot.
(CVE-2024-36489)
