Echo: linux: security update to 6.1.180-1

high Tenable Cloud Security Plugin ID 461808

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 reads in
 is_ap_in_tkip() IE loop The loop in is_ap_in_tkip() iterates over IEs without verifying that enough bytes
 remain before dereferencing the IE header or its payload: - pIE->element_id and pIE->length are read
 without checking that i + sizeof(*pIE) <= ie_length, so a truncated IE at the end of the buffer causes an
 OOB read. - For WLAN_EID_VENDOR_SPECIFIC the code compares pIE->data + 12, which requires pIE->length >=
 16. For WLAN_EID_RSN it compares pIE->data + 8, requiring pIE->length >= 12. Neither requirement is
 checked. Add the missing IE header and payload bounds checks and guard each data access with an explicit
 pIE->length minimum, matching the pattern established in update_beacon_info(). (CVE-2026-64536)

Solution

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