CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of association response frames in the cfg80211 module, where insufficient validation of the frame length can lead to improper initialization of critical fields. This flaw could potentially allow an attacker to exploit the system by sending malformed management frames, impacting the integrity and security of wireless connections. Organizations using Linux-based systems, particularly those relying on wireless networking, should prioritize addressing this vulnerability to mitigate potential risks.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: validate assoc response length before status and IE access cfg80211_rx_assoc_resp() initialises the status and response-IE fields of cfg80211_connect_resp_params from the management frame before proving that the frame is long enough for those offsets. S1G and regular association responses also have different IE offsets, but the S1G path only patched resp_ie after the unsafe initialiser had already run. Defer resp_ie, resp_ie_len, and status to after the link-iteration loop. Use a bool to remember whether the frame is S1G, then validate the appropriate minimum length and set all three fields in a single if/else block. Funnel short-frame and SME-reject cleanup through a shared free_bss label for the abandon paths.
