UBUNTU-CVE-2026-43424

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ftcm: Fix NULL pointer dereferences in nexus handling The tpg-tpgnexus pointer in the USB Target driver is dynamically managed and tied to userspace configuration via ConfigFS. It can be NULL if the USB host sends...

CVE-2026-43436

The CVE-2026-43436 vulnerability affects the Linux kernel ALSA USB-audio driver (Scarlett2 mixer quirk). A malformed USB descriptor can trigger a NULL dereference in scarlett2_find_fc_interface() due to assuming an endpoint exists. The patch adds a sanity check for bNumEndpoints and skips invalid...

CVE-2026-43432

CVE-2026-43432 relates to the Linux kernel USB xHCI driver. The error path in usb/xhci_disable_slot() previously freed only the command structure (via kfree), leaking the associated completion structure. The patch changes the code to call xhci_free_command() , which frees both the command structu...

CVE-2026-43432 usb: xhci: Fix memory leak in xhci_disable_slot()

In the Linux kernel, the following vulnerability has been resolved: usb: xhci: Fix memory leak in xhcidisableslot xhcialloccommand allocates a command structure and, when the second argument is true, also allocates a completion structure. Currently, the error handling path in xhcidisableslot only...

CVE-2026-43428

CVE-2026-43428 affects the Linux kernel USB core. The vulnerability arises from usb_control_msg(), usb_bulk_msg(), and usb_interrupt_msg() allowing unbounded, uninterruptible timeouts, which could hang a task indefinitely. The fix enforces a maximum timeout of 60 seconds and treats negative timeo...

CVE-2026-43429

In the Linux kernel, the following vulnerability has been resolved: USB: usbtmc: Use usbbulkmsgkillable with user-specified timeouts The usbtmc driver accepts timeout values specified by the user in an ioctl command, and uses these timeouts for some usbbulkmsg calls. Since the user can specify...

CVE-2026-43428

In the Linux kernel, the following vulnerability has been resolved: USB: core: Limit the length of unkillable synchronous timeouts The usbcontrolmsg, usbbulkmsg, and usbinterruptmsg APIs in usbcore allow unlimited timeout durations. And since they use uninterruptible waits, this leaves open the...
