CVE-2026-53152 Linux CVE debrief

Who should care

Linux kernel users, specifically those with systems using the dw_mmc-rockchip module, should be aware of this vulnerability. The vulnerability affects old SoCs (rk2928, rk3066, rk3188) that do not support UHS speeds. Users of these systems should ensure they update their kernel to a version that includes the fix.

Technical summary

The vulnerability is caused by the lack of private data for old controllers in the dw_mmc-rockchip module. The commit ff6f0286c896 made private data mandatory, but old SoCs do not have this data, leading to NULL-pointer dereferences. The fix involves giving the old types their private-data struct. The vulnerability has a CVSS score of null and a severity of null. The CVE record was published on 2026-06-25T09:16:32.573Z and modified on 2026-06-30T14:44:27.313Z.

Defensive priority

High priority should be given to patching the Linux kernel for systems using the dw_mmc-rockchip module, especially those with old SoCs (rk2928, rk3066, rk3188).

Recommended defensive actions

• Update the Linux kernel to a version that includes the fix for CVE-2026-53152.
• Ensure systems with old SoCs (rk2928, rk3066, rk3188) are identified and prioritized for patching.
• Monitor Linux kernel updates and apply patches as soon as possible.
• Verify that the dw_mmc-rockchip module is properly configured and updated.
• Perform regular vulnerability scans to detect potential issues.
• Implement compensating controls, such as monitoring and exception tracking, for systems that cannot be patched immediately.
• Review and update incident response plans to address potential exploitation of this vulnerability.

Evidence notes

The CVE record and NVD detail provide information on the vulnerability. The Linux kernel source code and commit history also provide evidence of the fix. However, the corpus is limited, and further analysis may be necessary to fully understand the vulnerability.
