Google: sys-kernel/csql-kernel-6_1, sys-kernel/csql-kernel-6_6: security update to 18613.613.5

medium Tenable Cloud Security Plugin ID 466099

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: reject direct access to nullable
 PTR_TO_BUF pointers check_mem_access() matches PTR_TO_BUF via base_type() which strips PTR_MAYBE_NULL,
 allowing direct dereference without a null check. Map iterator ctx->key and ctx->value are PTR_TO_BUF |
 PTR_MAYBE_NULL. On stop callbacks these are NULL, causing a kernel NULL dereference. Add a
 type_may_be_null() guard to the PTR_TO_BUF branch, matching the existing PTR_TO_BTF_ID pattern.
 (CVE-2026-43333)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.5 or later.
