| Proprietary Code CVEs | Description | CVSS Base Score | CVSS Vector String |
| CVE-2026-67271 | Dell PowerStore SDNAS, contains an Out-of-bounds Write vulnerability in the 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. | 9.8 | CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H  |
| CVE-2026-70415 | Dell PowerStore SDNAS contains a Buffer Copy without Checking Size of Input vulnerability in the NFS/RPC. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Command execution and Denial of service. | 8.1 | CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H |
| CVE-2026-67262 | Dell PowerStore contains a Missing Authorization vulnerability. An attacker with access to a mapped host could exploit this vulnerability to read from or write to LUNs that the host is not authorized to access, bypassing per-initiator LUN access controls and leading to protection mechanism bypass. | 8.8 | CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H |
