Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 5.4.189/5.10.111/5.15.34/5.17.3. This affects the function aqc111_rx_fixup. The manipulation with an unknown input leads to a out-of-bounds vulnerability. CWE is classifying the issue as CWE-125. The product reads data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: net: usb: aqc111: Fix out-of-bounds accesses in RX fixup aqc111_rx_fixup() contains several out-of-bounds accesses that can be triggered by a malicious (or defective) USB device, in particular: - The metadata array (desc_offset..desc_offset+2*pkt_count) can be out of bounds, causing OOB reads and (on big-endian systems) OOB endianness flips. - A packet can overlap the metadata array, causing a later OOB endianness flip to corrupt data used by a cloned SKB that has already been handed off into the network stack. - A packet SKB can be constructed whose tail is far beyond its end, causing out-of-bounds heap data to be considered part of the SKB's data. Found doing variant analysis. Tested it with another driver (ax88179_178a), since I don't have a aqc111 device to test it, but the code looks very similar.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2022-49051 since 02/26/2025. Technical details are known, but no exploit is available.

The vulnerability scanner Nessus provides a plugin with the ID 234484 (SUSE SLES15 Security Update : kernel (SUSE-SU-2025:1263-1)), which helps to determine the existence of the flaw in a target environment.
