Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2022-26358)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to RMRR (VT-d) and unity map (AMD-Vi) handling issues. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Resource exhaustion (CVE-ID: CVE-2022-26359)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to RMRR (VT-d) and unity map (AMD-Vi) handling issues. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Resource exhaustion (CVE-ID: CVE-2022-26360)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to RMRR (VT-d) and unity map (AMD-Vi) handling issues. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
4) Resource exhaustion (CVE-ID: CVE-2022-26361)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to RMRR (VT-d) and unity map (AMD-Vi) handling issues. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Race condition (CVE-ID: CVE-2022-26362)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to race condition in typeref acquisition Xen. A remote attacker can execute arbitrary code on the target system.
6) Buffer overflow (CVE-ID: CVE-2022-26363)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient care with non-coherent mappings. A remote attacker can pass a specially crafted data and trigger memory corruption and execute arbitrary code on the target system.
7) Buffer overflow (CVE-ID: CVE-2022-26364)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient care with non-coherent mappings. A remote attacker can pass a specially crafted data and trigger memory corruption and execute arbitrary code on the target system.
