CVE-2026-58088

The ELF core dump code counted the number of dumpable VM map entries, allocated a buffer for the corresponding program headers, then iterated over the map a second time to populate them. A process sharing the address space via rfork2 can mutate the map between the two passes, causing the second...

CVE-2026-58088

Affected: All supported FreeBSD versions. Root cause: A race condition in ELF core dump code — a second-pass write to the program-header buffer is not bounds-checked against the count from the first pass, so a process sharing the address space via rfork(2) can mutate the VM map between passes. Im...

Found FreeBSD 4.3 there is a design on the vulnerability, which allows the user in the other processes inserted in the signal handlers to. The problem is in the rforkRFPROC|RFSIGSHARE, if the child process exec a setuid program, then the parent process set up a signal handlers, the signal handler...
