Linux Kernel up to 7.0.12 net dma_sync_single_range_for_cpu improper synchronization

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel up to 7.0.12. This affects the function dma_sync_single_range_for_cpu of the component net. The manipulation with an unknown input leads to a improper synchronization vulnerability. CWE is classifying the issue as CWE-662. The product utilizes multiple threads or processes to allow temporary access to a shared resource that can only be exclusive to one process at a time, but it does not properly synchronize these actions, which might cause simultaneous accesses of this resource by multiple threads or processes. The impact remains unknown. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: sync RX data at the hardware packet offset mvpp2 programs the RX queue packet offset, so hardware writes received data at dma_addr + MVPP2_SKB_HEADROOM. The current CPU sync starts at dma_addr and only covers rx_bytes + MVPP2_MH_SIZE bytes, which syncs the unused headroom and misses the same number of bytes at the packet tail. On non-coherent DMA systems this can leave the CPU reading stale cache contents for the end of the received frame. Use dma_sync_single_range_for_cpu() with MVPP2_SKB_HEADROOM as the range offset so the sync covers the Marvell header and packet data actually written by hardware.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-53217 since 06/09/2026. The exploitability is told to be difficult. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 07/03/2026).

The vulnerability scanner Nessus provides a plugin with the ID 323539 (Linux Distros Unpatched Vulnerability : CVE-2026-53217), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 5.10.259, 5.15.210, 6.1.176, 6.6.143, 6.12.94, 6.18.36 or 7.0.13 eliminates this vulnerability. Applying the patch 60412bdd1b2576659eac23a23d2d9ff96228a643/19f8bc139e9b149d1e5bf75ae761d1bb8dd3e7d8/a3ad9b5767c89531fc7dae951b51b0933dcf7051/bede0f481b9137d73d1cf64309cbe4b94818a5d6/23548007b3c66d628fc7d6b80d1e23be04ea10d9/a13199fa224e9f776f4005d5037df03aa9ea8f37/e302206ad84a407a7e5f3f6fe767ff5efaace689/180235600934bef6add3be637c296d6cf3272e67 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.
