Published: January 17, 2025 / Updated: May 11, 2025


Vulnerability identifier: #VU102951
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-2024-49568
CWE-ID: CWE-20
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

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

The vulnerability exists due to improper input validation within the smc_clc_msg_prop_valid() function in net/smc/smc_clc.c, within the smc_find_rdma_v2_device_serv() function in net/smc/af_smc.c. A local user can perform a denial of service (DoS) attack.
