During driver initialization, an error in the init_task routine can leave essential structures such as vports and netdevs uninitialized. When the driver subsequently attempts to use these resources during a reset, the kernel dereferences a NULL pointer, causing a crash. This results in a system-wide denial of service and can allow local users to disrupt critical services.", "risk_and_exploitability": "With a CVSS base score of 5.5, the CVE represents moderate severity. The EPSS score indicates a negligible probability of automated exploitation (<1\u202f%). The vulnerability is not published in the CISA KEV catalog, and the current attack vector appears localized, as an attacker would need the ability to load or reload the idpf driver on a target system. If the embedded system cannot be updated immediately, the risk remains until the driver is patched or disabled."}}}}, "created": "2026-04-18T01:00:11.631313+00:00", "title": "Kernel NULL pointer dereference in idpf driver leads to crash", "updated": "2026-04-18T01:00:11.631329+00:00", "vendors": []}
