CVE-2022-48836: Input: aiptek - properly check endpoint type
First published: Tue Jul 16 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: Input: aiptek - properly check endpoint type Syzbot reported warning in usb_submit_urb() which is caused by wrong endpoint type. There was a check for the number of endpoints, but not for the type of endpoint. Fix it by replacing old desc.bNumEndpoints check with usb_find_common_endpoints() helper for finding endpoints Fail log: usb 5-1: BOGUS urb xfer, pipe 1 != type 3 WARNING: CPU: 2 PID: 48 at drivers/usb/core/urb.c:502 usb_submit_urb+0xed2/0x18a0 drivers/usb/core/urb.c:502 Modules linked in: CPU: 2 PID: 48 Comm: kworker/2:2 Not tainted 5.17.0-rc6-syzkaller-00226-g07ebd38a0da2 #0 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.14.0-2 04/01/2014 Workqueue: usb_hub_wq hub_event ...
