Command execution via STABS function-list corruption
Published Aug 31, 2026 · Updated Sep 4, 2026
Out-of-bounds write in GDB on affected Red Hat products allows local users to execute commands through a crafted ELF file. In read_member_functions(), destructor nodes remain linked after the list count is reduced, so copying the list writes beyond its allocated array. A user must open the ELF file and perform symbol inspection; the inferior process need not run, but successful corruption executes commands within GDB.
