Echo: linux: security update to 6.1.180-1

high Tenable Cloud Security Plugin ID 457171

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 heap buffer
overflow in rtw_cfg80211_set_wpa_ie() supplicant_ie is a 256-byte array in struct security_priv. The WPA
and WPA2 IE copy paths use: memcpy(padapter->securitypriv.supplicant_ie, &pwpa[0], wpa_ielen + 2); where
wpa_ielen is the raw IE length field (u8, 0-255). When a local user supplies a connect request via nl80211
with a crafted WPA IE of length 255, wpa_ielen + 2 equals 257, overflowing the 256-byte buffer by one byte
into the adjacent last_mic_err_time field. rtw_parse_wpa_ie() does not prevent this: its length
consistency check compares *(wpa_ie+1) against (u8)(wpa_ie_len-2), which is (u8)(255) == 255 when
wpa_ie_len = 257, so the check passes silently. Add explicit bounds checks for both the WPA and WPA2 paths
before the memcpy, rejecting any IE whose total size (wpa_ielen + 2) exceeds the supplicant_ie buffer.
(CVE-2026-64446)

Solution

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