CVE-2026-67271

Dell PowerStore SDNAS, contains an Out-of-bounds Write vulnerability in SMB/CIFS. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to denial of service and remote execution. This is a Critical vulnerability as a remote user could send a specially crafted SMB packet and cause a crash, that is persistent in case automatic restarts are enabled. Additionally, a more sophisticated attacker could use the same vulnerability for remote code execution.
