12) Integer overflow

EUVDB-ID: #VU72468

Risk: Low

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

CVE-ID: CVE-2023-23559

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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

The vulnerability exists due to integer overflow within the rndis_query_oid() function in drivers/net/wireless/rndis_wlan.c. A local user can trigger an integer overflow and execute arbitrary code with elevated privileges.

Mitigation

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

13) NULL pointer dereference

EUVDB-ID: #VU74126

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-2023-28328

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 within the az6027 driver in drivers/media/usb/dev-usb/az6027.c in the Linux Kernel. A local user can pass specially crafted data to the application and perform a denial of service (DoS) attack.

Mitigation

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

14) Use-after-free

EUVDB-ID: #VU76221

Risk: Low

CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-32269

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 net/netrom/af_netrom.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability requires that the system has netrom routing configured or the attacker must have the CAP_NET_ADMIN capability.

Mitigation

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