CVE-2022-1809

Process crash via uninitialized vtable analysis context

Published May 21, 2022 · Updated Aug 3, 2024

Uninitialized-pointer access in radare2 before 5.7.0 allows attackers to crash the process by triggering vtable analysis on a crafted file. In libr/anal/vtable.c, r_anal_list_vtables continues after r_anal_vtable_begin leaves RVTableContext.read_addr unset for an unsupported bit width. Exploitation requires local analysis of attacker-controlled input; the upstream patch and reproducer establish a process crash, not code execution.
