Echo: linux: security update to 6.1.162-1

medium Tenable Cloud Security Plugin ID 464170

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: mac80211: Discard Beacon frames
 to non-broadcast address Beacon frames are required to be sent to the broadcast address, see IEEE Std
 802.11-2020, 11.1.3.1 ("The Address 1 field of the Beacon .. frame shall be set to the broadcast
 address"). A unicast Beacon frame might be used as a targeted attack to get one of the associated STAs to
 do something (e.g., using CSA to move it to another channel). As such, it is better have strict filtering
 for this on the received side and discard all Beacon frames that are sent to an unexpected address. This
 is even more important for cases where beacon protection is used. The current implementation in mac80211
 is correctly discarding unicast Beacon frames if the Protected Frame bit in the Frame Control field is set
 to 0. However, if that bit is set to 1, the logic used for checking for configured BIGTK(s) does not
 actually work. If the driver does not have logic for dropping unicast Beacon frames with Protected Frame
 bit 1, these frames would be accepted in mac80211 processing as valid Beacon frames even though they are
 not protected. This would allow beacon protection to be bypassed. While the logic for checking beacon
 protection could be extended to cover this corner case, a more generic check for discard all Beacon frames
 based on A1=unicast address covers this without needing additional changes. Address all these issues by
 dropping received Beacon frames if they are sent to a non-broadcast address. (CVE-2025-71127)

Solution

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