Subject: [PATCH 1/2] linux: Disable io_uring
Date: Fri, 13 Oct 2023 09:03:00 +0000 [thread overview]
Message-ID: <d09d71ec-4501-44e7-ad47-631ebe654f91@ipfire.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 1946 bytes --]
This subsystem has been a frequent source of security vulnerabilities
affecting the Linux kernel; as a result, Google announced on June 14,
2023, that they would disable it in their environment as widely as
possible.
IPFire does not depend on the availability of io_uring. Therefore,
disable this subsystem as well in order to preemptively cut attack
surface.
