kernel: wifi: ath9k: Fix use-after-free in ath9k_hif_usb_disconnect()

A use-after-free flaw was discovered in the ath9k USB Wi-Fi driver in the Linux kernel. During the disconnect and deinitialization sequence ath9khifusbdisconnect, the driver could attempt to access its private data drvpriv after it has already been freed by the hardware teardown call...

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...
