Unity Linux 20.1070a Security Update: kernel (UTSA-2025-989709)
medium Nessus Plugin ID 272890
Synopsis
The Unity Linux host is missing one or more security updates.Description
The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-989709 advisory.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.
Tenable has extracted the preceding description block directly from the Unity Linux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the affected kernel package.See Also
