From ff917923f4fb9c83717ba135ee47d7e4c1567bb7 Mon Sep 17 00:00:00 2001 From: Muhammad Bilal Date: Tue, 28 Jul 2026 17:54:55 +0500 Subject: staging: rtl8723bs: fix OOB read in rtw_action_frame_parse() rtw_action_frame_parse() takes a frame_len parameter but never actually checks it before indexing into the frame body: const u8 *frame_body = frame + sizeof(struct ieee80211_hdr_3addr); ... c = frame_body[0]; ... a = frame_body[1]; frame_body already points 24 bytes (sizeof(struct ieee80211_hdr_3addr)) into frame, so reading frame_body[0] and frame_body[1] requires frame_len >= 26. A management action frame shorter than that (e.g. exactly 24 bytes, the minimum a malicious peer can send) causes a 1-2 byte out-of-bounds read. This is reachable from rtw_cfg80211_monitor_if_xmit_entry() and cfg80211_rtw_mgmt_tx() in ioctl_cfg80211.c, both of which pass attacker/user-influenced frame buffers and lengths straight through. Add the missing length check before frame_body is dereferenced.

SPDX-License-Identifier: GPL-2.0 + +Linux kernel project continuity +=============================== + +The Linux kernel development project is widely distributed, with over +100 maintainers each working to keep changes moving through their own +repositories. The final step, though, is a centralized one where changes +are pulled into the mainline repository. That is normally done by Linus +Torvalds but, as was demonstrated by the 4.19 release in 2018, there are +others who can do that work when the need arises. + +Should the maintainers of that repository become unwilling or unable to +do that work going forward (including facilitating a transition), the +project will need to find one or more replacements without delay. The +process by which that will be done is listed below. $ORGANIZER is the +last Maintainer Summit organizer or the current Linux Foundation (LF) +Technical Advisory Board (TAB) Chair as a backup. + +- Within 72 hours, $ORGANIZER will open a discussion with the invitees + of the most recently concluded Maintainers Summit. A meeting of those + invitees and the TAB, either online or in-person, will be set as soon + as possible in a way that maximizes the number of people who can + participate. + +- If there has been no Maintainers Summit in the last 15 months, the set of + invitees for this meeting will be determined by the TAB. + +- The invitees to this meeting may bring in other maintainers as needed. + +- This meeting, chaired by $ORGANIZER, will consider options for the + ongoing management of the top-level kernel repository consistent with + the expectation that it maximizes the long term health of the project + and its community. + +- Within two weeks, a representative of this group will communicate to the + broader community, using the ksummit@lists.linux.dev mailing list, what + the next steps will be. + +The Linux Foundation, as guided by the TAB, will take the steps +necessary to support and implement this plan. -- cgit v1.3.1
