Vulnerability from fkie_nvd - Published: 2026-06-25 09:16 - Updated: 2026-07-01 13:17

Severity

6.8 (Medium) - CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: USB: serial: io_ti: fix heap overflow in get_manuf_info() get_manuf_info() reads le16_to_cpu(rom_desc->Size) bytes from the device I2C EEPROM into a buffer allocated with kmalloc_obj(), which is sizeof(struct edge_ti_manuf_descriptor) = 10 bytes. The Size field comes from the device and is only validated (in check_i2c_image()) to make sure the descriptor fits within TI_MAX_I2C_SIZE (16384 bytes), not against the destination buffer size. A malicious USB device can therefore set Size to any value up to 16377, causing a heap overflow of up to 16367 bytes when plugged into a host running this driver. valid_csum() is called after read_rom() and also iterates buffer[0..Size-1], compounding the out-of-bounds access. Fix by rejecting descriptors with unexpected length before calling read_rom(). [ johan: amend commit message; also check for short descriptors ]

A malicious USB device, when plugged into a host running this driver, can exploit a heap overflow vulnerability in the `get_manuf_info()` function. This occurs because the driver does not properly validate the size of data read from the device\u0027s I2C EEPROM against the allocated memory buffer. This improper validation can lead to out-of-bounds memory writes, potentially allowing an attacker to execute arbitrary code or cause a system crash (Denial of Service)."
