Description
This security bulletin contains information about 1 security vulnerability.
1) Loop with unreachable exit condition ('infinite loop') (CVE-ID: CVE-2023-4010)
The vulnerability allows a local non-authenticated attacker to perform a denial of service (DoS) attack.
A flaw was found in the USB Host Controller Driver framework in the Linux kernel. The usb_giveback_urb function has a logic loophole in its implementation. Due to the inappropriate judgment condition of the goto statement, the function cannot return under the input of a specific malformed descriptor file, so it falls into an endless loop, resulting in a denial of service.
