8) Infinite loop

EUVDB-ID: #VU74631

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-1390

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in tipc_link_xmit() within the Linux kernel TIPC kernel module when parsing UDp packets. A remote attacker can send two small UDP packets to a system with a UDP bearer and consume all available CPU resources.

Mitigation

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