Improper locking in Linux kernel - CVE-2023-52516

Vulnerability identifier: #VU90804

CSH Severity: Low

CVSS v4 BT: 4.3 [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/E:U/U:Clear]

CVE-ID: CVE-2023-52516

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 __dma_entry_alloc(), __dma_entry_alloc_check_leak() and dma_entry_alloc() functions in kernel/dma/debug.c. A local user can perform a denial of service (DoS) attack.
