CVE-2022-47519

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, specifically with the missing validation of IEEE80211 P2P ATTR OPER CHANNEL in the cfg80211.c file. This can trigger an out-of-bounds write when parsing the channel list attribute from Wi-Fi management frames, potentially allowing 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 file to minimize the risk of exploitation. Avoid using the IEEE80211 P2P ATTR OPER CHANNEL attribute in the affected API endpoints until the issue is resolved.
