Improper locking in Linux kernel - CVE-2024-44951

Vulnerability identifier: #VU96856

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-2024-44951

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 sc16is7xx_set_baud(), sc16is7xx_handle_rx() and sc16is7xx_handle_tx() functions in drivers/tty/serial/sc16is7xx.c. A local user can perform a denial of service (DoS) attack.
