Security Bulletin

This security bulletin contains information about 29 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU64436

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-13695

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

The vulnerability exists in the Linux kernel's ACPI subsystem where a function does not flush the operand cache and causes a kernel stack dump. A local user can pass a specially crafted ACPI table to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism.

Mitigation

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

27) Double Free

EUVDB-ID: #VU63160

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-2022-28388

CWE-ID: CWE-415 - Double Free

Exploit availability: No

Description

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

The vulnerability exists due to boundary error in the usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c. A local user can pass specially crafted data to the application, trigger double free error and execute arbitrary code with elevated privileges.

Mitigation

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