Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A buffer overflow exists in the TH1520 AON firmware protocol driver. The issue occurs because the code uses unsafe pointer arithmetic to access the mode field through the resource pointer with an offset. Additionally, the driver used custom RPC SET BE* and RPC GET BE* macros instead of standard kernel endianness conversion macros.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
