En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:

dmaengine: ti: k3-udma-glue: corrección de una desreferencia de NULL en k3_udma_glue_release_rx_chn()

Si devm_kcalloc() para rx_chn->flows falla en una función de solicitud de canal, la ruta de error llama a k3_udma_glue_release_rx_chn(), que desreferencia el puntero NULL rx_chn->flows en k3_udma_glue_release_rx_flow().

Omita el bucle de liberación de flujos en k3_udma_glue_release_rx_chn() cuando rx_chn->flows no esté asignado.

Encontrado por Linux Verification Center (linuxtesting.org) con SVACE.
