Linux Flaw Exposes Multiple Distributions to Root Privilege Escalation

A single misstep in the Linux CIFS subsystem, dating back nearly two decades, leaves multiple distributions vulnerable to a devastating root privilege escalation attack, dubbed CIFSwitch. This flaw allows attackers to exploit the kernel's keyring mechanism and gain control of modern Linux systems.

Exploit 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.
