Description

This security bulletin contains information about 1 vulnerability.


1) Stack-based buffer overflow (CVE-ID: CVE-2026-64504)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: 7 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


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

The vulnerability exists due to a stack-based buffer overflow in __bmc150_accel_fifo_flush() when processing a device-reported FIFO frame count. An attacker with physical access can tamper with the I2C/SPI bus or use a malicious device that reports an oversized frame count to execute arbitrary code or cause a denial of service.

The issue can overwrite the stack canary, saved registers, and return address during FIFO data transfer.
