CVE-2026-89835

CVE-2026-89835 is a NULL pointer dereference in the Linux kernel's f2fs filesystem . When checkpoint_merge is enabled but no checkpoint thread is running (e.g., on a read-only mount), writing to ckpt_thread_ioprio via sysfs calls set_task_ioprio() on a NULL task pointer (cprc->f2fs_issue_ckpt)...

CVE-2026-89835 f2fs: avoid NULL checkpoint thread access in sysfs

In the Linux kernel, the following vulnerability has been resolved: f2fs: avoid NULL checkpoint thread access in sysfs checkpointmerge can be enabled even when no checkpoint merge thread is running. A read-only mount is one case: f2fs does not start f2fsissueckpt there, but ckptthreadioprio is...

CVE-2026-89828

This CVE affects the Linux kernel's amdgpu DRM driver . The root cause is an initialization ordering bug in amdgpu_vram_mgr_init(): the function drmm_cgroup_register_region() is called before the list heads and buddy allocator are initialized. If it fails, the early return skips those initializat...

CVE-2026-89822

In the Linux kernel , the drm/i915 driver is vulnerable to a NULL pointer dereference in i915_pci_probe(). When a device is force-bound via the sysfs driver_override mechanism, pci_match_device() returns a dummy pci_device_id_any entry whose driver_data field is NULL. The probe function unconditi...
