PT-2026-82240

Name of the Vulnerable Software and Affected Versions Denx U-Boot versions prior to 2026.04 Description An integer overflow exists in the ZFS filesystem support, which can be triggered by malformed on-disk metadata. This flaw may lead to incorrect memory allocation and subsequent out-of-bounds...

EUVD-2025-210793

An issue was discovered in Denx U-Boot before 2026.04. An integer overflow vulnerability in the ZFS filesystem support can be triggered by malformed on-disk metadata. The issue may result in incorrect memory allocation followed by out-of-bounds memory access, potentially leading to a crash or...

CVE-2026-49431

The ZFSIOCSETPROP ioctl, used by zfs-set8, incorrectly validated the calling user such that an unprivileged user is able to set metadata on a dataset indicating that the dataset has received properties from a zfs-recv8 stream. Any local user can set the internal ZFS metadata flag "$hasrecvd" on...

CVE-2026-49429

The ZFSIOCUSERSPACEMANY ioctl, used by zfs-userspace8, truncated a 64-bit output buffer size to a 32-bit integer for the kernel allocation, but used the original 64-bit size as the buffer limit when writing records. A local user with the "userused" delegated ZFS permission can trigger a kernel he...

CVE-2026-49430

The ZFSIOCRECVNEW ioctl, in the heal receive path, similarly truncated a 64-bit payload size to a 32-bit integer for allocation, then used the original 64-bit size as the length for a byteswap operation. A local user with the "receive" delegated ZFS permission can trigger kernel memory corruption...

EUVD-2026-62241

The ZFSIOCSETPROP ioctl, used by zfs-set8, incorrectly validated the calling user such that an unprivileged user is able to set metadata on a dataset indicating that the dataset has received properties from a zfs-recv8 stream. Any local user can set the internal ZFS metadata flag "$hasrecvd" on...

CVE-2026-49431

CVE-2026-49431 is an access control flaw in the OpenZFS component of FreeBSD (all supported versions). The ZFS_IOC_SET_PROP ioctl, used by zfs-set(8), incorrectly validated the calling user, allowing any unprivileged local user to set the internal ZFS metadata flag $hasrecvd on a dataset, falsely...

CVE-2026-49431 Incorrect user validation in ZFS_IOC_SET_PROP ioctl

The ZFSIOCSETPROP ioctl, used by zfs-set8, incorrectly validated the calling user such that an unprivileged user is able to set metadata on a dataset indicating that the dataset has received properties from a zfs-recv8 stream. Any local user can set the internal ZFS metadata flag "$hasrecvd" on...

CVE-2026-49430 Kernel heap overflow in ZFS_IOC_RECV_NEW ioctl

The ZFSIOCRECVNEW ioctl, in the heal receive path, similarly truncated a 64-bit payload size to a 32-bit integer for allocation, then used the original 64-bit size as the length for a byteswap operation. A local user with the "receive" delegated ZFS permission can trigger kernel memory corruption...

CVE-2026-49430

CVE-2026-49430 is a kernel memory corruption vulnerability in the OpenZFS component of FreeBSD , specifically in the ZFS_IOC_RECV_NEW ioctl within the heal receive path. The root cause is an integer truncation : a 64-bit payload size is truncated to 32 bits for buffer allocation, but the original...

CVE-2026-49429

A kernel heap overflow in the OpenZFS component of FreeBSD affects the ZFS_IOC_USERSPACE_MANY ioctl used by zfs-userspace(8). The root cause is a 64-bit to 32-bit truncation : the output buffer size is truncated to 32 bits for kernel allocation, but the original 64-bit value is used as the write ...
