Echo: linux: security update to 6.1.180-1

high Tenable Cloud Security Plugin ID 457296

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: staging: rtl8723bs: fix OOB write in
HT_caps_handler() HT_caps_handler() iterates pIE->length bytes and writes into HT_caps.u.HT_cap[], which
is a fixed 26-byte array (sizeof struct HT_caps_element). Because pIE->length is a raw u8 from an over-
the-air 802.11 AssocResponse frame and is never validated, a malicious AP can set it up to 255, causing up
to 229 bytes of out-of-bounds writes into adjacent fields of struct mlme_ext_info. Truncate the iteration
count to the size of HT_caps.u.HT_cap using umin() so that data from a longer-than-expected IE is silently
ignored rather than written out of bounds, preserving interoperability with APs that pad the element. An
early return on oversized IEs was considered but rejected: it would bypass the pmlmeinfo->HT_caps_enable =
1 assignment that precedes the loop, silently disabling HT mode for APs that append extra bytes to the HT
Capabilities IE. (CVE-2026-64440)

Solution

Update the linux library and its related packages to version 6.1.180-1 or later.
