Improper locking in Linux kernel - CVE-2025-22111

Published: April 22, 2025 / Updated: May 10, 2025


Vulnerability identifier: #VU107743
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-2025-22111
CWE-ID: CWE-667
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 locking within the sock_write_iter(), brioctl_set(), br_ioctl_call(), sock_ioctl() and compat_sock_ioctl_trans() functions in net/socket.c, within the dev_ifsioc() and dev_ioctl() functions in net/core/dev_ioctl.c, within the old_deviceless() and br_ioctl_stub() functions in net/bridge/br_ioctl.c. A local user can perform a denial of service (DoS) attack.
