Severity7.2High · CVSS 2.0

Active exploitationNonot in the CISA catalog
Public exploitAvailablePublished on Exploit-DB

The pkt_ioctl function in the pktcdvd block device ioctl handler (pktcdvd.c) in Linux kernel 2.6.12-rc4 and earlier calls the wrong function before passing an ioctl to the block device, which crosses security boundaries by making kernel address space accessible from user space and allows local users to cause a denial of service and possibly execute arbitrary code, a similar vulnerability to CVE-2005-1264.

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
