Echo: linux: security update to 6.1.164-1

medium Tenable Cloud Security Plugin ID 464161

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: net: stmmac: Fix accessing freed irq
 affinity_hint In stmmac_request_irq_multi_msi(), a pointer to the stack variable cpu_mask is passed to
 irq_set_affinity_hint(). This value is stored in irq_desc->affinity_hint, but once
 stmmac_request_irq_multi_msi() returns, the pointer becomes dangling. The affinity_hint is exposed via
 procfs with S_IRUGO permissions, allowing any unprivileged process to read it. Accessing this stale
 pointer can lead to: - a kernel oops or panic if the referenced memory has been released and unmapped, or
 - leakage of kernel data into userspace if the memory is re-used for other purposes. All platforms that
 use stmmac with PCI MSI (Intel, Loongson, etc) are affected. (CVE-2025-23155)

Solution

Update the linux library and its related packages to version 6.1.164-1 or later.
