  "details": "In the Linux kernel, the following vulnerability has been resolved:  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:  \tconst u8 *frame_body = frame + sizeof(struct ieee80211_hdr_3addr); \t... \tc = frame_body[0]; \t... \ta = 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 \u003e= 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.",
