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

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...

A local attacker using FreeBSD4. 3 design vulnerabilities to obtain system privilege-vulnerability warning-the black bar safety net

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...

CVE-2001-1180: Undefined Security Weakness

FreeBSD 4.3 does not properly clear shared signal handlers when executing a process, which allows local users to gain privileges by calling rfork with a shared signal handler, having the child process execute a setuid program, and sending a signal to the child...

CVE-2001-1047: Undefined Security Weakness

Race condition in OpenBSD VFS allows local users to cause a denial of service kernel panic by 1 creating a pipe in one thread and causing another thread to set one of the file descriptors to NULL via a close, or 2 calling dup2 on a file descriptor in one process, then setting the descriptor to NU...
