No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： 媒体驱动：dm1105：修复 dma_alloc_coherent 缺少错误检查的问题 dm1105_hw_init() 忽略了 dm1105_dma_map() 的返回值，而该函数负责处理 DMA 内存分配。当 dma_alloc_coherent() 失败时，驱动程序仍会使用空指针进行 DMA 传输，从而导致内核oops或无效硬件访问。 通过检查返回值并在失败时传播 -ENOMEM 来修复此问题。

Vulnerability Title
media: dm1105: fix missing error check for dma_alloc_coherent
Source: CVE Program / CVE List V5
Vulnerability Description
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.
