Published: 2026-01-31 | Last Modified: 2026-07-14 | Status: Modified

Description

In the Linux kernel, the following vulnerability has been resolved: dmaengine: at_hdmac: fix device leak on of_dma_xlate() Make sure to drop the reference taken when looking up the DMA platform device during of_dma_xlate() when releasing channel resources. Note that commit 3832b78b3ec2 ("dmaengine: at_hdmac: add missing put_device() call in at_dma_xlate()") fixed the leak in a couple of error paths but the reference is still leaking on successful allocation.

Additional Descriptions (1)

En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: dmaengine: at_hdmac: corregir fuga de dispositivo en of_dma_xlate() Asegúrese de liberar la referencia tomada al buscar el dispositivo de plataforma DMA durante of_dma_xlate() al liberar los recursos del canal. Tenga en cuenta que el commit 3832b78b3ec2 ('dmaengine: at_hdmac: añadir llamada put_device() faltante en at_dma_xlate()') corrigió la fuga en un par de rutas de error, pero la referencia aún se está fugando en una asignación exitosa.
