发布于3月6日3月6日 Members SUSE: CVE-2021-47285: SUSE Linux Security Advisory Severity 4 CVSS (AV:L/AC:M/Au:N/C:P/I:P/A:P) Published 05/21/2024 Created 08/16/2024 Added 08/09/2024 Modified 08/09/2024 Description In the Linux kernel, the following vulnerability has been resolved: net/nfc/rawsock.c: fix a permission check bug The function rawsock_create() calls a privileged function sk_alloc(), which requires a ns-aware check to check net->user_ns, i.e., ns_capable(). However, the original code checks the init_user_ns using capable(). So we replace the capable() with ns_capable().
