linux-aws-5.4 linux-raspi-5.4 vulnerabilities
Ye Zhang and Nicolas Wu discovered that the io_uring subsystem in the Linux
kernel did not properly handle locking for rings with IOPOLL, leading to a
double-free vulnerability. A local attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-21400)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
- TTY drivers;
- Netfilter;
- Network traffic control;
- VMware vSockets driver;
