CVE-2026-74459

CVE-2026-74459 (Linux kernel) affects the can: etas_es58x driver, specifically es58x_read_bulk_callback(). When RX URB resubmission fails (usb_submit_urb()), the callback currently does not release the allocated coherent transfer buffer, causing a buffer leak. The fixes documented in multiple sou...

CVE-2026-74458 can: kvaser_usb_leaf: kvaser_usb_leaf_wait_cmd(): validate received command extents

In the Linux kernel, the following vulnerability has been resolved: can: kvaserusbleaf: kvaserusbleafwaitcmd: validate received command extents The wait and bulk receive paths walk variable-length commands from a USB buffer. A nonzero command shorter than CMDHEADERLEN can still be dispatched, and...

CVE-2026-74458

Summary: CVE-2026-74458 affects the Linux kernel can: kvaser_usb_leaf code. The flaw allowed dispatch of variable-length USB commands when a nonzero command shorter than CMD_HEADER_LEN was received; a matching command could be copied into a caller-owned kvaser_cmd using the device-provided length...

CVE-2026-74455

The CVE-2026-74455 vulnerability in the Linux kernel concerns the peak_usb driver for CAN (uCAN) payloads. pcan_usb_fd_decode_buf() parses multiple CAN records packed in a single USB receive buffer and now requires each record to include the fixed header for its type and validates the CAN payload...

CVE-2026-74456

Summary (CVE-2026-74456): In the Linux kernel, the peak_usb path has a double-free in peak_usb_start() when URB_SUBMIT fails. Each RX URB transfer buffer is allocated with kmalloc() and flagged URB_FREE_BUFFER so that usb_free_urb() frees the transfer buffer. If usb_submit_urb() fails, the error ...
