-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2026-752186819e 2026-07-20 00:53:11.635413+00:00 --------------------------------------------------------------------------------
Name : libseccomp Product : Fedora 44 Version : 2.6.1 Release : 2.fc44 URL : https://github.com/seccomp/libseccomp Summary : Enhanced seccomp library Description : The libseccomp library provides an easy to use interface to the Linux Kernel's syscall filtering mechanism, seccomp. The libseccomp API allows an application to specify which syscalls, and optionally which syscall arguments, the application is allowed to execute, all of which are enforced by the Linux Kernel.
