EUVDB-ID: #VU74126

Risk: Low

CVSSv4.0: 4.3 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

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

CVSSv4.0: 5.7 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

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.
