CVE-2026-43448

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A race condition exists in the nvme poll irqdisable() function. A device can be disabled by nvme dev disable() (called via nvme reset work()) between the time an IRQ is disabled and when it is re-enabled. This causes pci irq vector() to return different IRQ types (MSI-X versus INTx), leading to an unbalanced enable warning because the system attempts to enable an INTx IRQ that was never disabled.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
