Google: sys-kernel/csql-kernel-6_12, sys-kernel/csql-kernel-6_6: security update to 19216.104.3

medium Tenable Self-Hosted Container Security Plugin ID 472658

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: Explicitly check accesses to
bpf_sock_addr Syzkaller found a kernel warning on the following sock_addr program: 0: r0 = 0 1: r2 = *(u32
*)(r1 +60) 2: exit which triggers: verifier bug: error during ctx access conversion (0) This is happening
because offset 60 in bpf_sock_addr corresponds to an implicit padding of 4 bytes, right after msg_src_ip4.
Access to this padding isn't rejected in sock_addr_is_valid_access and it thus later fails to convert the
access. This patch fixes it by explicitly checking the various fields of bpf_sock_addr in
sock_addr_is_valid_access. I checked the other ctx structures and is_valid_access functions and didn't
find any other similar cases. Other cases of (properly handled) padding are covered in new tests in a
subsequent patch. (CVE-2025-40078)

Solution

Update the sys-kernel/csql-kernel-6_12 library and its related packages to version 19216.104.3 or later.
