Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2022-23818)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation on the model specific VM_HSAVE_PA register. A local user perform a denial of service (DoS) attack.
2) Buffer overflow (CVE-ID: CVE-2021-46762)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the SMU. A local user can corrupt SMU SRAM and perform a denial of service (DoS) attack.
3) Improper Certificate Validation (CVE-ID: CVE-2021-26406)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient parsing of Owner's Certificate Authority (OCA) certificates in SEV (AMD Secure Encrypted Virtualization) and SEV-ES user application. A local user can perform a denial of service (DoS) attack.
4) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2021-26356)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to a race condition in ASP bootloader. A local user can tamper with the SPI ROM, corrupt S3 data and gain access to sensitive information.
5) Stack-based buffer overflow (CVE-ID: CVE-2023-20520)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in ASP Bootloader. A local user can trigger a stack-based buffer overflow and execute arbitrary code with elevated privileges.
6) Input validation error (CVE-ID: CVE-2021-46764)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation of DRAM addresses in SMU. A local user can overwrite sensitive memory locations within the ASP and perform a denial of service (DoS) attack.
7) Out-of-bounds write (CVE-ID: CVE-2023-20524)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error. A a compromised ASP can send malformed commands to an ASP on another CPU, trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
8) Buffer overflow (CVE-ID: CVE-2021-46775)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in ABL. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.
9) Input validation error (CVE-ID: CVE-2021-46769)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to insufficient syscall validation in the ASP Bootloader. A local privileged user can execute arbitrary DMA copies and escalate privileges on the system.
10) Input validation error (CVE-ID: CVE-2021-46756)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation in SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader. A local user with a malicious Uapp or ABL can send malformed or invalid syscall to the bootloader and perform a denial of service (DoS) attack.
11) Out-of-bounds write (CVE-ID: CVE-2021-46763)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in the SMU. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
12) Input validation error (CVE-ID: CVE-2021-26397)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to insufficient address validation. A local user with a compromised ABL and UApp can corrupt sensitive memory locations and escalate privileges on the system.
13) Input validation error (CVE-ID: CVE-2021-26379)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to insufficient input validation of mailbox data in the SMU. A local user can coerce the SMU to corrupt SMRAM and execute arbitrary code with elevated privileges.
14) Memory leak (CVE-ID: CVE-2021-26371)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due memory leak. A compromised or malicious ABL or UApp can send a SHA256 system call to the bootloader and expose ASP memory to userspace.
15) Buffer overflow (CVE-ID: CVE-2021-26354)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in ASP. A malicious process can issue a system call from a compromised ABL, which can cause arbitrary memory values to be initialized to zero, leading to loss of integrity and a potential crash.
