Summary

usr/log.c in iscsid in open-iscsi (iscsi-initiator-utils) before 2.0-865 uses a semaphore with insecure permissions (world-writable/world-readable) for managing log messages using shared memory, which allows local users to cause a denial of service (hang) by grabbing the semaphore.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
