CVE-2026-89628

A flaw was found in the Human Interface Device HID picolcd driver in the Linux kernel. A local attacker with root privileges, by using a specially crafted or spoofed picoLCD device, could exploit an out-of-bounds read vulnerability in the picolcddebugeepromread function. This flaw occurs because...
