USN-8645-1: Linux kernel (Oracle) vulnerabilities
Researchers found that the Linux kernel's WiFi code had a flaw making it possible for an attacker near your device to inject harmful data packets. This happened because a previous fix was incorrect. Beyond this, multiple security weaknesses were found in the Linux kernel that could let attackers compromise your system. Updates are available to fix these security problems in many areas of the kernel.

USN-8530-2: Linux kernel (HWE) vulnerabilities
A security issue was found in the Linux kernel used by Ubuntu systems, where the kernel did not handle certain shared memory fragments correctly during network operations. This problem, called Dirty Frag and related to two specific parts (XFRM ESP-in-TCP and RxRPC subsystems), could let a local attacker gain higher access privileges or escape from a container environment. Another similar flaw, called Fragnesia, also affects the XFRM ESP-in-TCP subsystem and poses the same risks. Additionally, several other vulnerabilities were found in various Linux kernel components, which might allow attackers to compromise the system.
