Description

This security bulletin contains information about 1 vulnerability.


1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2026-80788)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to uncontrolled resource allocation in nvmet_tcp_map_data() when processing a command containing an oversized SGL. A remote attacker can send a command with an oversized SGL to cause a denial of service.

Systems configured to panic on kernel warnings can panic when the allocation triggers a page-allocator warning.
