4) Security restrictions bypass (CVE-ID: CVE-2022-26373)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/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 potentially sensitive information.

The vulnerability exists due to non-transparent sharing of return predictor targets between contexts in Intel CPU processors. A local user can bypass the expected architecture isolation between contexts and gain access to sensitive information on the system.

5) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2022-29900)

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: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 mistrained branch predictions for return instructions. A local user can execute arbitrary speculative code under certain microarchitecture-dependent conditions. The vulnerability was dubbed  RETbleed.

6) 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.

7) OS Command Injection (CVE-ID: CVE-2022-30123)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

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

The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation when handling input passed via Rack's Lint middleware and CommonLogger middleware. A remote unauthenticated attacker can pass specially crafted data to the application and execute arbitrary OS commands on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

8) OS Command Injection (CVE-ID: CVE-2022-3276)

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

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

The vulnerability allows a remote user to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation. A remote user can pass specially crafted data to the application and execute arbitrary OS commands on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

9) Improper Authorization (CVE-ID: CVE-2022-41974)

CWE-ID: CWE-285 - Improper Authorization

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/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 incorrectly implemented authorization process within multipathd daemon. A local unprivileged user can bypass build-in authorization and execute privileged commands on the system.

10) UNIX symbolic link following (CVE-ID: CVE-2022-41973)

CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/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 symlink following issue. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.

Successful exploitation of this vulnerability may result in privilege escalation.

11) Double Free (CVE-ID: CVE-2022-2588)

CWE-ID: CWE-415 - Double Free

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

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

The vulnerability exists due to a double free error within the network packet scheduler implementation in the route4_change() function in Linux kernel when removing all references to a route filter before freeing it. A local user can run a specially crafted program to crash the kernel or execute arbitrary code.
