Analyst207Exploit Released for PinTheft Linux Flaw
A critical Linux flaw, dubbed PinTheft, has been exploited, allowing local attackers to gain root privileges on affected systems through a complex vulnerability in the Reliable Datagram Sockets (RDS) code. This security gap can be triggered by a specific interaction between RDS zerocopy and io_uring fixed buffers.

AnisseThe tokio documentation recommends against using tokio for reading a lot of files.
But this is obsolete, Alice says, becuase now in tokio, File IO will use io_uring transparently.
BusterMQ, Thread-per-core NATS server in Zig with io_uring
Paul RichardsIf I have a single threaded application using io_uring submit a batch of file reads then wait for them all to complete, and if _all_ the data being read was already in the page cache, then is it the case that no parallelism occurs?
As I understand it parallelism on file reads only occurs if data has to be read from the device, and it’s in the form of multiple reads being sent off to the storage hardware in parallel (or at least with QD > 1).

PostgreSQL Database Lands Initial Support For IO_uring: "Can Be Considerably Faster"
As a very exciting improvement for the open-source PostgreSQL database server, it has merged initial support for making use of IO_uring on Linux servers for asynchronous I/O and can provide for some nice performance improvements.
