Linux · Linux Kernel · CVE-2022-49051
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
The `aqc111 rx fixup()` function in the Linux kernel contains multiple out-of-bounds accesses that can be triggered by a defective or malicious USB device. These issues include the metadata array potentially being out of bounds, leading to out-of-bounds reads and endianness flips on big-endian systems. Additionally, a packet may overlap the metadata array, causing subsequent endianness flips to corrupt data in a cloned SKB (Socket Buffer) already processed by the network stack. Furthermore, a packet SKB can be created with a tail extending far beyond its end, resulting in out-of-bounds heap data being treated as part of the SKB data. This can impact the confidentiality, integrity, and availability of protected information.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
