Description
In the Linux kernel, the following vulnerability has been resolved: staging: ks7010: potential buffer overflow in ks_wlan_set_encode_ext() The "exc->key_len" is a u16 that comes from the user. If it's over IW_ENCODING_TOKEN_MAX (64) that could lead to memory corruption.

Executive Summary

This vulnerability is a potential buffer overflow in the Linux kernel's ks7010 wireless driver, specifically in the function ks_wlan_set_encode_ext(). It occurs because the key length (exc->key_len), which is a 16-bit unsigned integer provided by the user, can exceed the maximum allowed size (IW_ENCODING_TOKEN_MAX, which is 64). If the key length is larger than this limit, it can cause memory corruption.

Impact Analysis

If exploited, this buffer overflow vulnerability could lead to memory corruption in the Linux kernel. This may result in system instability, crashes, or potentially allow an attacker to execute arbitrary code with kernel privileges, compromising the security and reliability of the affected system.
