State: Published
Severity: Not scored

Reserved: Aug 9, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

net: wwan: t7xx: destroy DMA pool on CLDMA late init failure

t7xx_cldma_late_init() creates md_ctrl->gpd_dmapool before initializing the TX and RX rings. If any ring initialization fails, the error path frees the already initialized rings but leaves the DMA pool allocated.

Destroy md_ctrl->gpd_dmapool on the late-init failure path to avoid leaking the DMA pool.
