Security Bulletin

This security bulletin contains information about 31 vulnerabilities.

1) Deadlock

EUVDB-ID: #VU73186

Risk: Low

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

CVE-ID: CVE-2022-4269

CWE-ID: CWE-833 - Deadlock

Exploit availability: No

Description

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

The vulnerability exists due to an error in the Linux kernel Traffic Control (TC) subsystem. A local user can use a specific network configuration (redirecting egress packets to ingress using TC action "mirred") to trigger a CPU soft lockup.

Mitigation

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

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Use-after-free

EUVDB-ID: #VU75333

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-2022-45884

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error in drivers/media/dvb-core/dvbdev.c in Linux kernel related to dvb_register_device() function dynamically allocating fops. 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-2023-2002

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

Exploit availability: Yes

Description

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

The vulnerability exists due to improper permissions check in the Bluetooth subsystem when handling ioctl system calls of HCI sockets. A local user can acquire a trusted socket, leading to unauthorized execution of management commands.

Mitigation

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

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

The vulnerability exists due to a race condition in Qualcomm EMAC Gigabit Ethernet Controller. An attacker with physical access to system can remove the device before cleanup in the emac_remove() function is called, trigger a use-after-free error and crash the kernel.

Mitigation

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

31) Race condition

EUVDB-ID: #VU77958

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-2023-35828

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 escalate privileges on the system.

The vulnerability exists due to a race condition within the renesas_usb3_remove() function in drivers/usb/gadget/udc/renesas_usb3.c. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.

Mitigation

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