15) Input validation error

EUVDB-ID: #VU64377

Risk: Low

CVSSv4.0: 4.3 [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]

CVE-ID: CVE-2022-21180

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation in Memory Mapped I/O (MMIO) for some 14nm Client/Xeon E3 Intel® Processors. A local user can pass specially crafted input and perform a denial of service (DoS) attack in certain virtualized environments.

Mitigation

Update the affected package the Linux Kernel to the latest version.

17) Missing initialization of resource

EUVDB-ID: #VU61211

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-24448

CWE-ID: CWE-909 - Missing initialization of resource

Exploit availability: No

Description

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

The vulnerability exists due to missing initialization of resource within the fs/nfs/dir.c in the Linux kernel. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.

Mitigation

Update the affected package the Linux Kernel to the latest version.

CVE-ID: CVE-2022-30594

CWE-ID: CWE-276 - Incorrect Default Permissions

Exploit availability: No

Description

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

The vulnerability exists due to mishandling seccomp permissions. A local user can bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag and escalate privileges on the system.

Mitigation

Update the affected package the Linux Kernel to the latest version.
