Google: sys-kernel/csql-kernel-6_1, sys-kernel/csql-kernel-6_6: security update to 18613.439.81

medium Tenable Cloud Security Plugin ID 466093

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: arch_topology: Fix incorrect error
 check in topology_parse_cpu_capacity() Fix incorrect use of PTR_ERR_OR_ZERO() in
 topology_parse_cpu_capacity() which causes the code to proceed with NULL clock pointers. The current logic
 uses !PTR_ERR_OR_ZERO(cpu_clk) which evaluates to true for both valid pointers and NULL, leading to
 potential NULL pointer dereference in clk_get_rate(). Per include/linux/err.h documentation,
 PTR_ERR_OR_ZERO(ptr) returns: "The error code within @ptr if it is an error pointer; 0 otherwise." This
 means PTR_ERR_OR_ZERO() returns 0 for both valid pointers AND NULL pointers. Therefore
 !PTR_ERR_OR_ZERO(cpu_clk) evaluates to true (proceed) when cpu_clk is either valid or NULL, causing
 clk_get_rate(NULL) to be called when of_clk_get() returns NULL. Replace with !IS_ERR_OR_NULL(cpu_clk)
 which only proceeds for valid pointers, preventing potential NULL pointer dereference in clk_get_rate().
 (CVE-2025-40346)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.439.81 or later.
