CVE-2026-90043

CVE-2026-90043 affects the zram module in the Linux kernel on 64-bit big-endian systems. The root cause is a bit-position aliasing bug: the slot lock bit is computed over the entire __lock word, where flags and ac_time alias as two u32 values. On big-endian, the lock bit lands in the ac_time half...

CVE-2026-90031

CVE-2026-90031 affects the Linux kernel's ene_ub6250 USB storage driver. The root cause is a race condition on the shared us->current_urb field: the delayed scan work (via usb_stor_Bulk_max_lun()) and the probe path (via ene_get_card_type()) both access it concurrently, with only the scan path...

CVE-2026-90022 usb: gadget: f_midi2: fix use-after-free in string attribute show path

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: fmidi2: fix use-after-free in string attribute show path fmidi2optsstrshow takes the string lock internally, but its callers dereference the opts-info. pointer before calling it, outside the lock. This races with...

CVE-2026-90020 USB: gadget: fix NULL pointer dereference in gadget_dev_ioctl()

In the Linux kernel, the following vulnerability has been resolved: USB: gadget: fix NULL pointer dereference in gadgetdevioctl gadgetdevioctl reads dev-gadget before acquiring dev-lock, but dev-state is checked after acquiring the lock. Therefore a concurrent bind can change the device state...

CVE-2026-90020

CVE-2026-90020 affects the Linux kernel USB gadget subsystem. The vulnerability is a race condition in gadget_dev_ioctl(): the function reads dev->gadget before acquiring dev->lock, but checks dev->state only after acquiring the lock. A concurrent bind can change the device state between...

CVE-2026-90002 ftrace: Take trace_array reference before accessing its ftrace_ops

CVE-2026-90001

A race condition in the Linux kernel HID BPF subsystem allows __hid_bpf_ops_destroy_device() and hid_bpf_unreg() to double-put the struct hid_device reference, freeing the device while hid_destroy_device() is still using it. The root cause is a TOCTOU flaw: the two paths run under different lock ...
