CVE-2014-9491

Status: ModifiedMedium (5)—

The devzvol_readdir function in illumos does not check the return value of a strchr call, which allows remote attackers to cause a denial of service (NULL pointer dereference and panic) via unspecified vectors.

CVSS

Exploitation probability (EPSS)

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).
