kernel: wifi: ath9k: hif_usb: Fix use-after-free in ath9k_hif_usb_reg_in_cb()

A flaw was found in the ath9k USB Wi-Fi driver in the Linux kernel. In certain conditions within the ath9khifusbregincb path, a socket buffer skb may be freed prematurely and then freed again on an error path, leading to a use-after-free condition. Additionally, failure to allocate a new skb can...

kernel: Linux kernel: Denial of Service in ath9k Wi-Fi driver due to URB memory leak

A flaw was found in the Linux kernel's ath9k Wi-Fi driver. This memory leak vulnerability occurs because Universal Serial Bus USB request blocks URBs are allocated but not properly freed when certain conditions are met during USB device handling. A local attacker could exploit this by triggering...

kernel: wifi: ath9k: avoid referencing uninit memory in ath9k_wmi_ctrl_rx

A flaw was identified in the Linux kernel’s ath9k wireless driver where the receiver packet handling code did not correctly validate the length of incoming SKBs before accessing subsequent fields expected to be present. In certain malformed packet conditions e.g., pktlen set too small, the driver...
