      "title": "staging: rtl8723bs: fix xmit_frame/xmit_buf leaks on mgnt-frame error paths",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nstaging: rtl8723bs: fix xmit_frame/xmit_buf leaks on mgnt-frame error paths\n\nissue_beacon(), issue_probersp() and issue_asocrsp() obtain a management\nxmit_frame together with its xmit_buf from the driver's fixed-size\nmanagement-TX pools via alloc_mgtxmitframe(). On the normal path the frame\nis handed to dump_mgntframe(), which transfers ownership and eventually\nreturns both objects to their pools (the frame and, for beacons, the buf\nin rtl8723bs_mgnt_xmit(); other bufs via the pending-xmitbuf/TX-completion\npath).\n\nSeveral error/edge paths return early after a successful\nalloc_mgtxmitframe() but before dump_mgntframe(), so ownership is never\ntransferred and neither object is freed:\n\n  - issue_beacon(): beacon larger than 512 bytes\n  - issue_probersp(): cur_network->ie_length > MAX_IE_SZ\n  - issue_probersp(): kzalloc() of the SSID scratch buffer fails\n  - issue_asocrsp(): pkt_type is neither ASSOCRSP nor REASSOCRSP\n\nBecause alloc_mgtxmitframe() removes the frame and buf from their free\nlists (list_del_init) without placing them on any pending list, an\norphaned pair is on no list and referenced by nobody, so it is only\nreclaimed at driver teardown. Repeated hits progressively exhaust the\nmanagement-TX pools until alloc_mgtxmitframe() returns NULL and the\ninterface can no longer send beacons or probe/assoc responses.\n\nFree the frame and buffer on these paths, matching the existing correct\nerror handling in issue_assocreq().",
