CVE-2006-5726

Status: ModifiedMedium (4.9)—💥 Exploit

alloccgblk in the UFS filesystem in Solaris 10 allows local users to cause a denial of service (memory corruption) by mounting crafted UFS filesystems with malformed data structures.

CVSS

Version: 2.0
Vector: AV:L/AC:L/Au:N/C:N/I:N/A:C
Base score: 4.9

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.82%
Percentile among all scored CVEs: 56
Score date: 10/8/2026

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.
