A vulnerability named EntrySign (CVE-2024-36347) affects some AMD Zen processors due to improper verification of CPU microcode signatures. This flaw allows a privileged attacker to potentially load malicious CPU microcode, leading to loss of system integrity and confidentiality. Additionally, numerous other security issues were discovered and fixed in the Linux kernel across many subsystems and architectures. These vulnerabilities collectively could allow attackers to compromise affected systems. The issues are addressed in updated Linux kernel packages for the linux-oracle and linux-oracle-6.8 distributions.
