Memory Allocation Failure in Linux Kernel dm1105 Driver

Publication date: 2026-09-24

Last updated on: 2026-09-24

Assigner: kernel.org

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.

Executive Summary

This vulnerability is in the Linux kernel's media driver dm1105. It occurs when the driver fails to check if DMA memory allocation succeeds. If dma_alloc_coherent() fails, the driver continues using a NULL pointer for DMA transfers, which can cause a kernel crash (oops) or invalid hardware access.

Detection Guidance

This vulnerability is specific to the Linux kernel's dm1105 driver and involves a missing error check for DMA memory allocation. Detection requires checking if the system is running a vulnerable kernel version and inspecting the dm1105 driver for the described issue. No direct network detection commands are applicable.

Impact Analysis

If exploited, this flaw could lead to system instability, crashes, or potential unauthorized access to hardware resources. Users running affected Linux kernel versions with the dm1105 driver may experience kernel panics or unexpected behavior.

Mitigation Strategies

Apply the kernel patch that includes the fix for the dm1105 driver error check. Update to a kernel version where the vulnerability is resolved. If patching is not immediately possible, consider disabling the dm1105 driver if it is not required.
