Security Bulletin

This security bulletin contains information about 62 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.

CVE-ID: CVE-2022-3586

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error in the way the sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed) into a child qdisc. A local user can perform a denial of service (DoS) attack.

Mitigation

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

CVE-ID: CVE-2022-41218

CWE-ID: CWE-416 - Use After Free

Exploit availability: Yes

Description

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

The vulnerability exists due to a use-after-free error within the dvb_demux_open() and dvb_dmxdev_release() function in drivers/media/dvb-core/dmxdev.c in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Mitigation

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

CVE-ID: CVE-2022-41848

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

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

The vulnerability exists due to a race condition in the drivers/char/pcmcia/synclink_cs.c in the Linux kernel. An attacker with physical proximity to the affected system can remove a PCMCIA device while calling ioctl, cause a race condition between mgslpc_ioctl and mgslpc_detach and perform a denial of service (DoS) attack.

Mitigation

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