How to fix?

Upgrade SLES:15.2 kernel-default-devel to version 5.3.18-150200.24.194.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-devel package and not the kernel-default-devel package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

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.
