In the Linux kernel, the following vulnerability has been resolved: can: esdusb: esdusbreadbulkcallback: fix URB memory leak Fix similar memory leak as in commit 7352e1d5932a "can: gsusb: gsusbreceivebulkcallback: fix URB memory leak". In esdusbopen, the URBs for USB-in transfers are allocated,...

CVE-2026-23075

CVE-2026-23075 affects the Linux kernel CAN networking support. The issue arises from the esd_usb_read_bulk_callback() path where URBs for USB-in transfers are unanchored by the USB core after completion, leading to a memory leak if esd_usb_close() frees URBs that are no longer anchored. The fix ...
