In the Linux kernel, the following vulnerability has been resolved: ALSA: firewire: isight: bound the sample count to the packet payload isightpacket takes the frame count from the device iso packet and checks it only against the device claimed iso length. count = be32tocpupayload-samplecount; if...

CVE-2026-64483

CVE-2026-64483 affects the Linux kernel ALSA: firewire isight driver. The vulnerability arises when isight_packet() reads frame counts from the device iso packet and validates only against length, allowing a count up to (length-16)/4. Since payload->samples holds 2 * MAX_FRAMES_PER_PACKET valu...
