About this tag
The spi driver tag on WindowsForum.com covers Linux kernel vulnerabilities in specific SPI (Serial Peripheral Interface) drivers, particularly the spi-topcliff-pch and spi-sprd-adi drivers. Recent discussions focus on CVE-2026-46301, a use-after-free bug in the spi-topcliff-pch driver triggered during unbind before DMA buffers are released, and CVE-2026-23068, a double-free vulnerability in the spi-sprd-adi driver caused by lifecycle mismanagement during probe failure. These threads highlight the importance of kernel security patching, especially in teardown and error-handling paths. While the vulnerabilities are hardware-specific, they serve as reminders for administrators to maintain rigorous patch processes.

    CVE-2026-46301: Linux spi-topcliff-pch DMA Use-After-Free on Unbind

    CVE-2026-46301 is a newly published Linux kernel vulnerability, added to NVD on June 8, 2026, affecting the spi-topcliff-pch driver when it is unbound before its SPI message queue has finished using DMA buffers. The bug is narrow, hardware-specific, and not yet scored by NVD, but it is a useful...

    CVE-2026-23068 Double-Free in Linux spi-sprd-adi: Devm Lifecycle Fix

    CVE-2026-23068 is a reminder that some of the Linux kernel’s most consequential security issues are not dramatic logic bugs, but lifecycle mistakes in error handling. In this case, the vulnerable code path sits in the spi-sprd-adi driver, where a controller allocated one way and released another...
