Description

In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: k3-udma-glue: fix NULL dereference in k3_udma_glue_release_rx_chn() If devm_kcalloc() for rx_chn->flows fails in a channel request function, the error path calls k3_udma_glue_release_rx_chn(), which dereferences the NULL rx_chn->flows pointer in k3_udma_glue_release_rx_flow(). Skip the flow release loop in k3_udma_glue_release_rx_chn() when rx_chn->flows is not allocated. Found by Linux Verification Center (linuxtesting.org) with SVACE.
