1) Memory corruption

EUVDB-ID: #VU92801

Risk: Low

CVSSv4.0: 6.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2015-4004

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to access sensitive information or perform a denial of service (DoS) attack.

The OZWPAN driver in the Linux kernel through 4.0.5 relies on an untrusted length field during packet parsing, which allows remote attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read and system crash) via a crafted packet.

Mitigation

Install update from vendor's repository.

Vulnerable software versions

Linux kernel: All versions
