CVE-2026-97989

In the Linux kernel, the following vulnerability has been resolved: vduse: validate virtqueue alignment vdusevalidateconfig only checks the upper bound of vqalign. Invalid values can therefore reach vringcreatevirtqueuemap. The split-ring helpers use align - 1 as a bit mask, so the alignment must...

CVE-2026-97992

The Linux kernel contains a use-after-free vulnerability in the vhost-vdpa component. The issue occurs because vhost_vdpa_config_cb() accesses v->config_ctx without holding a lock or taking a reference, while VHOST_VDPA_SET_CONFIG_CALL replaces the field and immediately frees the old context v...

EUVD-2026-86646

In the Linux kernel, the following vulnerability has been resolved: vhost-vdpa: protect configctx from being freed under the config callback vhostvdpaconfigcb loads v-configctx and signals it without taking a reference and without holding any lock: struct eventfdctx configctx = v-configctx; if...

CVE-2026-97989

The Linux kernel contains a vulnerability in vduse where vduse_validate_config() fails to properly validate the vq_align parameter, checking only the upper bound. This allows invalid values to reach vring_create_virtqueue_map(). Specifically, because split-ring helpers use align - 1 as a bit mask...

CVE-2026-97989 vduse: validate virtqueue alignment

In the Linux kernel, the following vulnerability has been resolved: vduse: validate virtqueue alignment vdusevalidateconfig only checks the upper bound of vqalign. Invalid values can therefore reach vringcreatevirtqueuemap. The split-ring helpers use align - 1 as a bit mask, so the alignment must...

EUVD-2026-86637

In the Linux kernel, the following vulnerability has been resolved: vduse: return compat ioctl results directly The compat handler handles VDUSEIOTLBGETFD and VDUSEVQGETINFO, but then calls the native handler. Their different command sizes make native dispatch return -ENOIOCTLCMD. For GETFD, this...

CVE-2026-97983

The Linux kernel contains a vulnerability in the vduse component where the compat handler incorrectly calls the native handler for VDUSE_IOTLB_GET_FD and VDUSE_VQ_GET_INFO commands. Because these commands have different sizes, the native dispatch returns -ENOIOCTLCMD, which overwrites the return ...

Astra Linux – Vulnerability in Linux 5.15

A flaw was discovered in vDPA with the VDUSE backend. Currently, there are no checks in the VDUSE kernel driver to ensure that the size of the device configuration space is consistent with the features advertised by the VDUSE user-space application. In the event of a mismatch, the Virtio driver...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: vduse: Fixed NULL pointer dereferencing during sysfs access. The control device does not have a drvdata. Therefore, we will encounter a NULL pointer dereference when accessing the msgtimeout attribute of the control device via...

SUSE CVE-2026-72305

In the Linux kernel, the following vulnerability has been resolved: VDUSE: avoid leaking information to userspace The bounceing is not necessarily page aligned, so current VDUSE can leak kernel information through mapping bounce pages to userspace. Allocate bounce pages with GFPZERO to avoid...

SUSE CVE-2026-72306

In the Linux kernel, the following vulnerability has been resolved: vduse: Fix race in vdusedevmsgsync and vdusedevreaditer There is one race case in vdusedevmsgsync and vdusedevreaditer: vdusedevreaditer: lockmsglock; dequeuemsgsendlist; unlockmsglock; vdusedevmsgsync: waittimeout finish...

SUSE CVE-2026-74313

In the Linux kernel, the following vulnerability has been resolved: vduse: hold vduselock across IDR lookup in open path vdusedevopen looks up struct vdusedev through the IDR and then acquires dev-lock only after vduselock has been dropped. This leaves a window where a concurrent VDUSEDESTROYDEV...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: vduse: It is necessary to hold the vduselock during the IDR lookup in the open path. The vdusedevopen function looks up the struct vdusedev through the IDR, and then acquires dev-lock only after the vduselock has been released...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: vduse: Fixed a race condition in vdusedevmsgsync and vdusedevreaditer. There is one race condition in vdusedevmsgsync and vdusedevreaditer: vdusedevreaditer: lockmsglock; dequeuemsgsendlist; unlockmsglock; vdusedevmsgsync:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: VDUSE: Avoid leaking information to userspace. The bouncing of memory pages does not necessarily require page alignment; therefore, current VDUSE may still leak kernel information by mapping bounce pages to userspace. Allocate...

CVE-2026-74313

A flaw was found in the Linux kernel's vduse component. A race condition in the vdusedevopen function allows a memory object to be freed while still in use. This use-after-free vulnerability could enable a local attacker to cause a system crash denial of service or potentially execute arbitrary...
