EUVDB-ID: #VU68339

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

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.

EUVDB-ID: #VU68340

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:P/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-41849

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

Exploit availability: No

Description

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

The vulnerability exists due to a race condition in the drivers/video/fbdev/smscufx.c in the Linux kernel. An attacker with physical proximity to the system can remove the USB device while calling open(), cause a race condition between the ufx_ops_open and ufx_usb_disconnect and perform a denial of service (DoS) attack.

Mitigation

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

EUVDB-ID: #VU68313

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-42719

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in the mac80211 stack in Linux kernel when parsing a multi-BSSID element. A remote attacker on the local network can send specially crafted WLAN frames to the affected system, trigger a use-after-free error and execute arbitrary code.
