Detailsinfo

A vulnerability was found in Linux Kernel up to 5.4.264/5.10.204/5.15.143/6.1.68/6.6.7. It has been rated as critical. Affected by this issue is the function skb_trim of the component aqc111. The manipulation with an unknown input leads to a wrap-around vulnerability. Using CWE to declare the problem leads to CWE-128. Wrap around errors occur whenever a value is incremented past the maximum value for its type and therefore "wraps around" to a very small, negative, or undefined value. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: usb: aqc111: check packet for fixup for true limit If a device sends a packet that is inbetween 0 and sizeof(u64) the value passed to skb_trim() as length will wrap around ending up as some very large value. The driver will then proceed to parse the header located at that position, which will either oops or process some random value. The fix is to check against sizeof(u64) rather than 0, which the driver currently does. The issue exists since the introduction of the driver.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2023-52655 since 03/06/2024. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 248449 (Linux Distros Unpatched Vulnerability : CVE-2023-52655), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 5.4.265, 5.10.205, 5.15.144, 6.1.69 or 6.6.8 eliminates this vulnerability.
