CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HIn the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Clamp frame size in implicit-feedback mode snd_usb_handle_sync_urb() scales received sync packet sizes by the sender's stride and stores the result directly in out_packet->packet_size[i]. If a connected USB device sends an oversized sync packet, this frame count can exceed ep->maxframesize. The un-clamped frame count then propagates to the playback endpoint queue, potentially driving packet transfers beyond the endpoint's hardware frame limits. Cap the calculated frame count against ep->maxframesize in snd_usb_handle_sync_urb() to prevent oversized packets from entering the playback queue.
Multiple vulnerabilities have been discovered in the Linux kernel of Debian. These vulnerabilities allow for privilege escalation, data compromise, and denial of service. The affected Debian versions are prior to 6.12.10…
