CVE-2022-47521

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.0.11

Description The issue is related to the WILC1000 wireless driver in the Linux kernel, where missing validation of IEEE80211 P2P ATTR CHANNEL LIST in drivers/net/wireless/microchip/wilc1000/cfg80211.c can trigger a heap-based buffer overflow when parsing the operating channel attribute from Wi-Fi management frames. This can potentially allow an attacker to execute arbitrary code or cause a denial of service.

Recommendations For Linux kernel versions prior to 6.0.11, update to version 6.0.11 or later to resolve the issue. As a temporary workaround, consider disabling the WILC1000 wireless driver until a patch is available. Restrict access to the vulnerable cfg80211.c module to minimize the risk of exploitation. Avoid using the IEEE80211 P2P ATTR CHANNEL LIST attribute in the affected API endpoints until the issue is resolved.
