Improper locking in Linux kernel - CVE-2024-26785

Vulnerability identifier: #VU92040

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-2024-26785

CWE-ID: CWE-667

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 locking within the iommufd_test_syz_conv_iova(), iommufd_test_syz_conv_iova_id(), iommufd_test_access_pages() and iommufd_test_access_rw() functions in drivers/iommu/iommufd/selftest.c. A local user can perform a denial of service (DoS) attack.
