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

media: dm1105: fix missing error check for dma alloc coherent

The return value of dm1105 dma map(), which handles DMA memory allocation, is ignored in dm1105 hw init(). If dma alloc coherent() fails, the driver will proceed using a NULL pointer for DMA transfers, leading to a kernel oops or invalid hardware access.

Fix this by checking the return value and propagating -ENOMEM on failure.
