A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

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.
