CVE-2024-22396Network attack vector

Service interruption via crafted IKEv2 payload

Published Mar 14, 2024 · Updated Aug 1, 2024

Integer overflow in SonicWall SonicOS allows remote authenticated users to interrupt firewall service with a crafted IKEv2 payload. SonicWall identifies an integer-based buffer overflow in IPsec processing but does not disclose the affected function or incorrect arithmetic operation. Reachability requires low privileges and specific, high-complexity conditions; arbitrary code execution remains a potential rather than demonstrated impact.
