CVE-2026-58088 Race condition in ELF core dump segment counting
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
A race condition exists in the FreeBSD ELF core dump code, affecting all supported versions. The vulnerability occurs because the kernel counts dumpable VM map entries and allocates a buffer for program headers, but a process sharing the address space via rfork(2) can mutate the map between the c...
