linux / linux_kernel

Description

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix xmit_frame/xmit_buf leaks on mgnt-frame error paths issue_beacon(), issue_probersp() and issue_asocrsp() obtain a management xmit_frame together with its xmit_buf from the driver's fixed-size management-TX pools via alloc_mgtxmitframe(). On the normal path the frame is handed to dump_mgntframe(), which transfers ownership and eventually returns both objects to their pools (the frame and, for beacons, the buf in rtl8723bs_mgnt_xmit(); other bufs via the pending-xmitbuf/TX-completion path). Several error/edge paths return early after a successful alloc_mgtxmitframe() but before dump_mgntframe(), so ownership is never transferred and neither object is freed: - issue_beacon(): beacon larger than 512 bytes - issue_probersp(): cur_network->ie_length > MAX_IE_SZ - issue_probersp(): kzalloc() of the SSID scratch buffer fails - issue_asocrsp(): pkt_type is neither ASSOCRSP nor REASSOCRSP Bec
