Last modified Jun 17, 2026

CVE-2019-12802 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In radare2 through 3.5.1, the rcc_context function of libr/egg/egg_lang.c mishandles changing context. This allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact (invalid memory access in r_egg_lang_parsechar; invalid free in rcc_pusharg).. EPSS estimates a 1.59% chance of exploitation in the next 30 days.
