Threats tagged 'ghsa-mq9h-jmwj-r2r4'

rtl_433 versions through 25.12 have a stack-based buffer overflow vulnerability in the proflame2_mc() function. This flaw allows an attacker within radio range to send more than seven valid Manchester-coded words, overflowing a 7-byte stack buffer. Exploitation can cause rtl_433 to crash and potentially corrupt stack memory, enabling control-flow hijacking on builds lacking stack canaries.
