      "title": "staging: rtl8723bs: fix OOB read in WMM_param_handler()",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix OOB read in WMM_param_handler()\n\nWMM_param_handler() copies a fixed-size WMM parameter element out of a\nreceived information element without checking that the element is long\nenough, causing an out-of-bounds read for a short WMM IE.\n\nThe handler reads sizeof(struct WMM_para_element) (18) bytes at\npIE->data + 6, so it requires pIE->length to be at least 24\n(WLAN_WMM_LEN), but it never validates the length. Two of its three\ncallers reach it after matching only the WMM OUI: OnAssocRsp() in\nrtw_mlme_ext.c matches a 6-byte OUI, and join_cmd_hdl() matches a\n4-byte OUI, before calling the handler. A vendor-specific IE carrying\nthe WMM OUI but a length between 6 and 23, placed in an association\nresponse or in the IE blob handed to join_cmd_hdl(), passes the OUI\ncheck and then makes the memcmp() and memcpy() at pIE->data + 6 read\npast the end of the element. OnAssocRsp() parses a frame received from\nthe AP, so this is reachable from a remote peer.\n\nThe remaining caller in rtw_wlan_util.c already guards the handler with\n\"pIE->length == WLAN_WMM_LEN\". Move the equivalent check into the\nhandler itself so every caller is covered; the sibling IE handlers in\nthe same parsing loop (HT_caps_handler(), HT_info_handler(),\nERP_IE_handler()) likewise bound their accesses by pIE->length.",
