Heap-based buffer overflow in Linux kernel - CVE-2026-53196

Published: June 26, 2026


Vulnerability identifier: #VU135582
CSH Severity: Medium
CVSS v4: 5.1 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
CVE-ID: CVE-2026-53196
CWE-ID: CWE-122
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows an attacker with physical access to cause a denial of service or execute arbitrary code.

The vulnerability exists due to a heap-based buffer overflow in get_manuf_info() in the io_ti USB serial driver when processing a crafted USB device EEPROM descriptor. An attacker with physical access can connect a malicious USB device with a forged Size field to trigger the overflow and cause a denial of service or execute arbitrary code.

The out-of-bounds access is compounded because a checksum routine also iterates over the device-controlled length after the EEPROM data is read.
