Memory Corruption when accessing trusted execution environment without proper privilege check. [CVSS 7.8 HIGH]
IBM PowerVM Hypervisor FW1110.00 through FW1110.03, FW1060.00 through FW1060.51, and FW950.00 through FW950.F0 may expose a limited amount of data to a peer partition in specific shared processor configurations during certain operations. [CVSS 2.8 LOW]
In GPU pdma, there is a possible memory corruption due to a missing permission check. This could lead to local denial of service with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS10117735; Issue ID: MSV-4539.
CVE-2023-20599 is an improper register access control vulnerability in AMD's ASP (AMD Secure Processor) that allows a privileged local attacker to gain unauthorized access to the Crypto Co-Processor (CCP) registers, potentially compromising cryptographic key management and leading to loss of confidentiality or integrity. The vulnerability affects AMD EPYC and Ryzen processors with ASP implementations. While the CVSS score of 7.9 indicates high severity, exploitation requires high privilege level (PR:H) and local access (AV:L), limiting real-world attack surface; however, this is an actively tracked vulnerability relevant to data center and workstation security.
Cryptographic issue may arise because the access control configuration permits Linux to read key registers in TCSR. Rated medium severity (CVSS 6.5), this vulnerability is low attack complexity. No vendor patch available.
