CVE-2026-2261 blocklistd(8) socket leak

Due to a programming error, blocklistd leaks a socket descriptor for each adverse event report it receives. Once a certain number of leaked sockets is reached, blocklistd becomes unable to run the helper script: a child process is forked, but this child dereferences a null pointer and crashes...

CVE-2026-2261

The CVE-2026-2261 issue affects blocklistd where a programming error leaks a socket descriptor per adverse event, eventually exhausting file descriptors. After a moderate number of leaks, the process cannot run the helper script because a forked child dereferences a null pointer and crashes, prev...

CVE-2025-15576 Jail chroot escape via fd exchange with a different jail

If two sibling jails are restricted to separate filesystem trees, which is to say that neither of the two jail root directories is an ancestor of the other, jailed processes may nonetheless be able to access a shared directory via a nullfs mount, if the administrator has configured one. In this...

CVE-2025-15576

CVE-2025-15576 describes a jail/chroot escape in FreeBSD. When two sibling jails are restricted to separate filesystem trees, processes in the two jails can still exchange directory descriptors via a unix domain socket and access a shared directory mounted with nullfs. During a filesystem name lo...
