CVE-2023-54300

CVE-2023-54300 affects the Linux kernel wireless driver stack (ath9k). The issue arises from uninitialized memory access in ath9k_wmi_ctrl_rx triggered by missing pkt_len validation in ath9k_htc_rx_msg; the SKB could be malformed such that a WMI header is expected in data but not present. The fix...
