About this tag
The driver core tag on WindowsForum.com covers discussions about the foundational kernel infrastructure that manages device-driver binding, including the driver_override mechanism. Recent content focuses on a Linux kernel vulnerability (CVE-2026-31487) in the SPI subsystem where improper locking in the driver core's override logic could lead to a use-after-free. The fix involves moving SPI to the generic driver_override infrastructure to centralize locking while maintaining SPI-specific sysfs behavior. This tag is relevant for developers and system administrators working with Linux kernel internals, device drivers, and security patches.

    Linux Kernel Proposal Would Add Y Taint to VFIO Bind/Unbind Hosts

    Greg Kroah-Hartman has proposed a new Linux kernel taint flag, TAINT_FORCED_BIND. It would mark a running kernel whenever someone uses the driver-core bind or unbind sysfs files to manually attach a device to a driver or detach it. He says he wants this because fuzzers such as syzbot have been...

    CVE-2026-31487: SPI driver_override use-after-free and the safe generic fix

    CVE-2026-31487 is a reminder that some of the most consequential Linux kernel bugs are not loud crashes or dramatic memory-corruption chains, but quiet lifetime mistakes hidden inside core infrastructure. In this case, the issue sits in the SPI subsystem’s interaction with the kernel’s...
