Linux kernel is the kernel used by the Linux Foundation’s open source operating system, Linux. Linux kernel is vulnerable to a denial of service. The vulnerability is due to the ability of affected versions of the Linux kernel to inject WLAN frames into the mac80211 stack of a local attacker could launch a NULL pointer dereference denial of service attack against the beacon protection of a P2P device. An attacker could use the vulnerability to launch a targeted attack against the target, compromising site system security.
