14) Type Confusion

EUVDB-ID: #VU71478

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-2023-23454

CWE-ID: CWE-843 - Type confusion

Exploit availability: No

Description

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

The vulnerability exists due to a type confusion error within the cbq_classify() function in net/sched/sch_cbq.c in the Linux kernel. A local user can trigger a type confusion error and crash the kernel.

Mitigation

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