Input validation error in Linux kernel - CVE-2025-38216

Vulnerability identifier: #VU112333

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2025-38216

CWE-ID: CWE-20

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the intel_nested_attach_dev() function in drivers/iommu/intel/nested.c, within the dmar_domain_attach_device(), device_block_translation() and identity_domain_attach_dev() functions in drivers/iommu/intel/iommu.c. A local user can perform a denial of service (DoS) attack.
