Security Bulletin

This security bulletin contains information about 20 vulnerabilities.

1) NULL pointer dereference

EUVDB-ID: #VU63789

Risk: Low

CVSSv3.1: 3.9 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-0168

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to a NULL pointer dereference error in the Linux kernel’s smb2_ioctl_query_info function in the fs/cifs/smb2ops.c Common Internet File System (CIFS). A privileged (CAP_SYS_ADMIN) attacker can perform a denial of service (DoS) attack.

Mitigation

Update the affected package linux to the latest version.

2) Use-after-free

EUVDB-ID: #VU63428

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1048

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a local user to execute arbitrary code with elevated privileges.

The vulnerability exists due to a use-after-free error in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. A local user can execute arbitrary code with elevated privileges and perform a denial-of-service attack.

Mitigation

Update the affected package linux to the latest version.

12) Memory leak

EUVDB-ID: #VU64076

Risk: Low

CVSSv3.1: 5.2 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1651

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a local privileged user to perform DoS attack on the target system.

The vulnerability exists due memory leak in the Linux kernel in acrn_dev_ioctl in the drivers/virt/acrn/hsm.c() function in how the ACRN Device Model emulates virtual NICs in VM. A local privileged user can leak unauthorized kernel information, causing a denial of service.

Mitigation

Update the affected package linux to the latest version.
