CVE-2026-80574

A flaw was found in the Linux kernel's focaltech input driver. This vulnerability occurs in the focaltechprocessrelpacket function, where incorrect handling of input can lead to an array out-of-bounds write. This memory corruption issue could potentially allow an attacker to cause system...

CVE-2026-80574

CVE-2026-80574 is an array out-of-bounds write in the Linux kernel's Focaltech input driver, specifically in the focaltech_process_rel_packet function. The root cause is that the finger1 and finger2 variables are signed; when a packet carries a finger index of 0, subtracting 1 yields -1 , which b...
