22) 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 the Linux Kernel to the latest version.

25) NULL pointer dereference

EUVDB-ID: #VU61270

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-2022-25258

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to a NULL pointer dereference error drivers/usb/gadget/composite.c in the Linux kernel. The USB Gadget subsystem lacks certain validation of interface OS descriptor requests (ones with a large array index and ones associated with NULL function pointer retrieval). A local user can run a specially crafted program to trigger memory corruption and perform a denial of service (DoS) attack.

Mitigation

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

32) Double Free

EUVDB-ID: #VU63164

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-2022-28390

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 ems_usb_start_xmit in drivers/net/can/usb/ems_usb.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.

33) Memory leak

EUVDB-ID: #VU63419

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-28748

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows an attacker to gain access to sensitive information.

The vulnerability exists due memory leak when working with ax88179_178a devices. An attacker with physical access to the system can inject a malicious USB-drive and remotely obtain data from kernel memory.

Mitigation

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