Memory Access Vulnerability in Linux Kernel's mac80211_hwsim for Wireless Networking

CVE-2023-53321

What is CVE-2023-53321?

A vulnerability exists in the Linux kernel's mac80211_hwsim module that improperly handles shorter control frames, leading to potential memory access issues. This allows for the transmission of frames without the complete 3-address header, which can lead to accessing invalid memory if shorter frames are processed. To mitigate this risk, updates to ensure all control frames are validated before forwarding are necessary.
