Good morning. This is Linux Kernel Daily for June 6th, 2026.
The dominant theme today is security vulnerability remediation, with graphics drivers receiving the most extensive fixes and one critical ioctl being temporarily disabled.
The most significant change involves the DRM gem change handle ioctl, which has been disabled entirely after multiple failed attempts to fix race conditions between gem close and gem change handle operations. Commit 8e65320 documents four separate fix attempts that introduced new bugs while trying to resolve…
Graphics drivers saw widespread hardening with bounds checking and memory safety fixes. The AMD GPU driver received fixes for buffer overflows in SDMA queue handling, null pointer dereferences in queue management, and use-after-free races in the KFD subsystem. The Ethosu accelerator driver had particularly extensive…
Virtualization security was strengthened with KVM fixes addressing GHCB handling vulnerabilities in SEV environments. The changes ensure proper unmapping and unpinning of guest-host communication blocks during vCPU cleanup, and implement exact-once reading of page size change request indices to prevent…
Filesystem stability improved with…
