Multiple security vulnerabilities were discovered in the Linux kernel for Oracle Cloud systems (linux-oracle-5.15). These include flaws in cryptographic operations, socket buffer handling, and ptrace subsystem race conditions. Local attackers could exploit these issues to escalate privileges or escape containers, and one flaw could expose sensitive information. The vulnerabilities affect versions prior to 5.15.0-1106.112~20.04.1. A security update fixing these issues is available and should be applied promptly.
