AI-suggested
A fix is available that adds proper error checking for dma_alloc_coherent() in the dm1105 driver and propagates an error code on failure. Users should apply the official Linux kernel updates that include this fix to remediate the vulnerability.
Description
A vulnerability in the Linux kernel media driver dm1105 was fixed by adding a missing error check for dma_alloc_coherent. Without this check, if dma_alloc_coherent fails, the driver proceeds with a NULL pointer for DMA transfers, which can cause a kernel oops or invalid hardware access.
