Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath9k: add range check for conn_rsp_epid in htc_connect_service()

I found the following bug in my fuzzer:

UBSAN: array-index-out-of-bounds in drivers/net/wireless/ath/ath9k/htc_hst.c:26:51 index 255 is out of range for type 'htc_endpoint [22]' CPU: 0 UID: 0 PID: 8 Comm: kworker/0:0 Not tainted 6.11.0-rc6-dirty #14 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 Workqueue: events request_firmware_work_func Call Trace: <TASK> dump_stack_lvl+0x180/0x1b0 __ubsan_handle_out_of_bounds+0xd4/0x130 htc_issue_send.constprop.0+0x20c/0x230 ? _raw_spin_unlock_irqrestore+0x3c/0x70 ath9k_wmi_cmd+0x41d/0x610 ? mark_held_locks+0x9f/0xe0 ...

Since this bug has been confirmed to be caused by insufficient verification of conn_rsp_epid, I think it would be appropriate to add a range check for conn_rsp_epid to htc_connect_service() to prevent the bug from occurring.
