In OpenBSD 7.4 before errata 014, vmm(4) did not restore GDTR limits properly on Intel (VMX) CPUs.

In OpenBSD 7.4 before errata 006 and OpenBSD 7.3 before errata 020, httpd(8) is vulnerable to a NULL dereference when handling a malformed fastcgi request.

In OpenBSD 7.5 before errata 009 and OpenBSD 7.4 before errata 022, exclude any '/' in readdir name validation to avoid unexpected directory traversal on untrusted file systems.

In OpenBSD 7.5 before errata 008 and OpenBSD 7.4 before errata 021, avoid possible mbuf double free in NFS client and server implementation, do not use uninitialized variable in error handling of NFS server.

The NVMe driver queue processing is vulernable to guest-induced infinite loops.

The hda driver is vulnerable to a buffer over-read from a guest-controlled value.

A guest can trigger an infinite loop in the hda audio driver.

The virtio_vq_recordon function is subject to a time-of-check to time-of-use (TOCTOU) race condition.

The NVMe driver function nvme_opc_get_log_page is vulnerable to a buffer over-read from a guest-controlled value.

The fetch(3) library uses environment variables for passing certain information, including the revocation file pathname. The environment variable name used by fetch(1) to pass the filename to the library was incorrect, in effect ignoring the option. Fetch would still connect to a host presenting a certificate included in the revocation file passed to the --crl option.
