Security Bulletin

This security bulletin contains information about 8 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU61215

Risk: Low

CVSSv3.1: 4 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-43976

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input within the mwifiex_usb_recv() function in drivers/net/wireless/marvell/mwifiex/usb.c in Linux kernel. An attacker with physical access to the system can insert a specially crafted USB device and perform a denial of service (DoS) attack.

Mitigation

Update the affected package linux to the latest version.

6) Missing initialization of resource

EUVDB-ID: #VU61211

Risk: Low

CVSSv3.1: 3.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-24448

CWE-ID: CWE-909 - Missing initialization of resource

Exploit availability: No

Description

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

The vulnerability exists due to missing initialization of resource within the fs/nfs/dir.c in the Linux kernel. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.

Mitigation

Update the affected package linux to the latest version.
