Echo: linux: security update to 6.1.162-1

medium Tenable Self-Hosted Container Security Plugin ID 460901

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: wifi: rtl818x: rtl8187: Fix potential
 buffer underflow in rtl8187_rx_cb() The rtl8187_rx_cb() calculates the rx descriptor header address by
 subtracting its size from the skb tail pointer. However, it does not validate if the received packet
 (skb->len from urb->actual_length) is large enough to contain this header. If a truncated packet is
 received, this will lead to a buffer underflow, reading memory before the start of the skb data area, and
 causing a kernel panic. Add length checks for both rtl8187 and rtl8187b descriptor headers before
 attempting to access them, dropping the packet cleanly if the check fails. (CVE-2025-68362)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
