CVE-2026-89851 scsi: qla2xxx: Fix FCE trace enable parsing in debugfs

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix FCE trace enable parsing in debugfs qla2x00dfsfcewrite called kstrtoul with a NULL result pointer, so a successful parse would dereference NULL and oops. Worse, the int return value 0 on success, negative errno...

CVE-2026-89851

A bug in the Linux kernel scsi: qla2xxx driver (QLogic SCSI) affected the FCE trace enable write handler in debugfs (qla2x00_dfs_fce_write()). The function called kstrtoul() with a NULL result pointer , so a successful parse would dereference NULL and trigger a kernel oops . Additionally, the int...

CVE-2026-89849

This vulnerability affects the qla2xxx SCSI driver in the Linux kernel . The root cause is a logic flaw in qla2x00_status_entry(): after filtering out certain SRB types, the code falls through to a SCSI fast path that unconditionally assumes the command is an SRB_SCSI_CMD. Because the srb union o...

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-2026-89828

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 drm/i915: Guard against NULL driver_data in i915_pci_probe()

In the Linux kernel, the following vulnerability has been resolved: drm/i915: Guard against NULL driverdata in i915pciprobe pcimatchdevice can return the dummy pcideviceidany entry when a device is force-bound via sysfs driveroverride, in which case -driverdata is unset NULL. i915pciprobe casts i...

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...
