USN-7089-7: Linux kernel (Low Latency) vulnerabilities

Chenyuan Yang discovered that the USB Gadget subsystem in the Linux
kernel did not properly check for the device to be enabled before
writing. A local attacker could possibly use this to cause a denial of
service. (CVE-2024-25741)

Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
