Published Updated By the CyberSecBulletin desk

CVE-2026-82715 is a high-severity vulnerability in Hitachi Disk Array Driver for AIX from Hitachi, with a CVSS 3.1 base score of 7.9 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 01-23-/A as the first without the flaw, so updating Hitachi Disk Array Driver for AIX to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.12% chance of exploitation within 30 days, which is low compared with other CVEs.
