CVE-2026-23324
Description
A flaw was found in the Linux kernel's etas_es58x USB CAN bus driver. The driver fails to correctly anchor the USB Request Block (urb) in the read bulk callback. This oversight can lead to a memory leak if usb_kill_anchored_urbs() is called without the urb being properly anchored. The continuous leakage of memory could result in system instability or a Denial of Service (DoS).
