Improper input validation in Linux kernel

1) Improper input validation

EUVDB-ID: #VU94810

Risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2005-1264

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a local user to execute arbitrary code.

Raw character devices (raw.c) in the Linux kernel 2.6.x call the wrong function before passing an ioctl to the block device, which crosses security boundaries by making kernel address space accessible from user space, a similar vulnerability to CVE-2005-1589.

Mitigation

Install update from vendor's repository.
