CVE-2026-52978 Details
Description
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.
A vulnerability in the Linux kernel's netlink operations for managing PSP devices has been addressed. The 'dev-set' and 'key-rotate' operations, which modify shared device state and cryptographic key material, respectively, previously did not require administrative permissions. This lack of proper access control could lead to unauthorized modifications. The vulnerability has been fixed by updating the operations to require administrative rights.
