| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.37
Description
The vulnerability is related to the serial component of the Linux kernel, specifically with the
uart handle cts change() function in serial core, which expects the caller to hold uport->lock. The issue arises when the Bluetooth driver is loaded on an i.MX28 board, leading to a kernel splat. The vulnerability can cause a denial of service.Recommendations
To resolve the issue, update the Linux kernel to version 6.6.37 or later. As a temporary workaround, consider disabling the Bluetooth driver until a patch is available. Restrict access to the vulnerable
mxs-auart module to minimize the risk of exploitation. Avoid using the uart handle cts change() function in the affected API endpoint until the issue is resolved.Exploit
