Details
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:

• Netfilter;
• Network traffic control;
• VMware vSockets driver;
• (CVE-2024-53164, CVE-2024-53103, CVE-2024-53141)

Update instructions
