CVE-2026-97928 drm/amdgpu: skip the VMID 0 flush for VRAM

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: skip the VMID 0 flush for VRAM Clear-on-release only runs on VRAM, which amdgputtmmapbuffer reaches via its direct MC address without programming a GART window, yet the wipe still forces a VMID 0 flush. On GFX11 e.g...

In the Linux kernel, the following vulnerability has been resolved: ufs: validate cylinder group metadata before caching it ufsreadcylinder copies the cylinder group index and the rotor positions straight from the on-disk group and caches them without any check: ucpi-ccgx = fs32tocpusb, ucg-cgcgx...

CVE-2026-97927 ufs: create the root dentry after loading cylinder metadata

In the Linux kernel, the following vulnerability has been resolved: ufs: create the root dentry after loading cylinder metadata ufsfillsuper installed sb-sroot before it loaded the cylinder group structures for a writable mount: sb-sroot = dmakerootinode; ... if !sbrdonlysb if...

CVE-2026-97927

The Linux kernel contains a vulnerability in the ufs filesystem where ufs_fill_super() installs the root dentry before successfully loading cylinder group structures for writable mounts. If ufs_read_cylinder_structures() fails, the error path frees the in-core superblock information and sets sb-&...

CVE-2026-97926

The Linux kernel contains a vulnerability in the ufs filesystem where ufs_read_cylinder() copies cylinder group index and rotor positions from on-disk groups into cache without validation. A crafted image can set these values to trigger out-of-bounds access during allocation or free operations. S...

CVE-2026-97925

A race condition exists in the Linux kernel during the replacement of a broadcast device . The issue occurs because tick_install_broadcast_device() is not serialized against concurrent tick broadcast operations. Specifically, a race between __tick_broadcast_oneshot_control() and tick_install_broa...

CVE-2026-97923

The Linux kernel contains a memory leak vulnerability within the tracing subsystem. Specifically, the create_var_ref() function allocates a VAR_REF hist_field and calls init_var_ref() to populate it. If init_var_ref() fails, the allocated field is leaked because it is not added to the trigger's v...

CVE-2026-97924

The Linux kernel contains a vulnerability in the tracing/user_events component. The destroy_user_event() function incorrectly destroys an event's fields before attempting to remove the trace event call. If the removal fails (e.g., returning -EBUSY because the event is still enabled), the event re...
