Description

This security bulletin contains information about 5 vulnerabilities.


1) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2022-29901)

CWE-ID: CWE-1037 - Processor optimization removal or modification of security-critical code

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to the way non-transparent sharing of branch predictor targets between contexts. A local user can exploit the vulnerability to gain access to sensitive information.


2) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2022-28693)

CWE-ID: CWE-1037 - Processor optimization removal or modification of security-critical code

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to unprotected alternative channel of return branch target prediction. A local user can gain access to sensitive information.


3) NULL pointer dereference (CVE-ID: CVE-2022-31681)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error. A local user with privileges within the VMX process only can perform a denial of service (DoS) attack against the host.


4) Buffer overflow (CVE-ID: CVE-2022-31696)

CWE-ID: CWE-119 - Memory corruption

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in the way network socket are handled. A local privileged user can trigger memory corruption and execute arbitrary code with elevated privileges.


5) Out-of-bounds write (CVE-ID: CVE-2022-31705)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error within the USB 2.0 controller (EHCI). A local privileged user on the guest OS can trigger an out-of-bounds write and execute arbitrary code as the virtual machine's VMX process running on the host.
