16) NULL pointer dereference

EUVDB-ID: #VU73769

Risk: Low

CVSSv4.0: 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-2023-23000

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to a NULL pointer dereference error within the tegra_xusb_find_port_node() function in drivers/phy/tegra/xusb.c. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.

Mitigation

Update the affected package the Linux Kernel to the latest version.
