kernel: iwlwifi: mvm: check debugfs_dir ptr before use

A denial of service vulnerability was found in the Linux kernel. When debugfs is set as off in the kernel command line, iwiwifi's mvm module uses an invalid/unchecked debugfsdir pointer, resulting in disruption to availability...

USN-5708-1 backport-iwlwifi-dkms vulnerabilities

Sönke Huster discovered that an integer overflow vulnerability existed in the WiFi driver stack in the Linux kernel, leading to a buffer overflow. A physically proximate attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2022-41674 Sönke Hust...
