In the Linux kernel, the following vulnerability has been resolved: can: etases58x: allow partial RX URB allocation to succeed When es58xallocrxurbs fails to allocate the requested number of URBs but succeeds in allocating some, it returns an error code. This causes es58xopen to return early,...

CVE-2026-46184

CVE-2026-46184 relates to the Linux kernel sound/ua101 driver. The root cause is a missing sanity check for bNrChannels in detect_usb_format(), which can lead to a division by zero in playback_urb_complete() and capture_urb_complete() when a device reports bNrChannels = 0. The USB core does not v...
