1) NULL pointer dereference (CVE-ID: CVE-2022-22232)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in the Packet Forwarding Engine on SRX Series routers, if Unified Threat Management (UTM) Enhanced Content Filtering (CF) is enabled. A remote attacker can send specific transit traffic to the device and force the PFE to crash and restart, resulting in a denial of service condition.
