Vulnerability from fkie_nvd - Published: 2026-06-24 17:17 - Updated: 2026-07-14 16:51
Severity
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: net: psp: require admin permission for dev-set and key-rotate The dev-set and key-rotate netlink operations modify shared device state (PSP version configuration and cryptographic key material, respectively) but do not require CAP_NET_ADMIN. The only access control is psp_dev_check_access() which merely verifies netns membership.
