Last modified Jun 17, 2026

CVE-2019-19647 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. radare2 through 4.0.0 lacks validation of the content variable in the function r_asm_pseudo_incbin at libr/asm/asm.c, ultimately leading to an arbitrary write. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via crafted input.. EPSS estimates a 1.57% chance of exploitation in the next 30 days.
