Linux Kernel up to 6.1.1 drivers/usb/core/urb.c usb_endpoints information disclosure

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Linux Kernel up to 6.1.1. It has been rated as problematic. Affected by this issue is the function usb_endpoints of the file drivers/usb/core/urb.c. The manipulation with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: wifi: ath9k: verify the expected usb_endpoints are present The bug arises when a USB device claims to be an ATH9K but doesn't have the expected endpoints. (In this case there was an interrupt endpoint where the driver expected a bulk endpoint.) The kernel needs to be able to handle such devices without getting an internal error. usb 1-1: BOGUS urb xfer, pipe 3 != type 1 WARNING: CPU: 3 PID: 500 at drivers/usb/core/urb.c:493 usb_submit_urb+0xce2/0x1430 drivers/usb/core/urb.c:493 Modules linked in: CPU: 3 PID: 500 Comm: kworker/3:2 Not tainted 5.10.135-syzkaller #0 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.12.0-1 04/01/2014 Workqueue: events request_firmware_work_func RIP: 0010:usb_submit_urb+0xce2/0x1430 drivers/usb/core/urb.c:493 Call Trace: ath9k_hif_usb_alloc_rx_urbs drivers/net/wireless/ath/ath9k/hif_usb.c:908 [inline] ath9k_hif_usb_alloc_urbs+0x75e/0x1010 drivers/net/wireless/ath/ath9k/hif_usb.c:1019 ath9k_hif_usb_dev_init drivers/net/wireless/ath/ath9k/hif_usb.c:1109 [inline] ath9k_hif_usb_firmware_cb+0x142/0x530 drivers/net/wireless/ath/ath9k/hif_usb.c:1242 request_firmware_work_func+0x12e/0x240 drivers/base/firmware_loader/main.c:1097 process_one_work+0x9af/0x1600 kernel/workqueue.c:2279 worker_thread+0x61d/0x12f0 kernel/workqueue.c:2425 kthread+0x3b4/0x4a0 kernel/kthread.c:313 ret_from_fork+0x22/0x30 arch/x86/entry/entry_64.S:299 Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
