Key facts

Description

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: Fix potential stack-out-of-bounds write in ath9k_wmi_rsp_callback() Fix a stack-out-of-bounds write that occurs in a WMI response callback function that is called after a timeout occurs in ath9k_wmi_cmd(). The callback writes to wmi->cmd_rsp_buf, a stack-allocated buffer that could no longer be valid when a timeout occurs. Set wmi->last_seq_id to 0 when a timeout occurred. Found by a modified version of syzkaller.
