The Linux Kernel, the operating system core itself. Security Fixes: In the Linux kernel, the following vulnerability has been resolved: driver core: platform: use generic driveroverride infrastructure When a driver is probed through driverattach, the bus' match callback is called without the devi...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: RISCV: Vector: Fixed the context saving/restoring with xtheadvector. Previously, only v0-v7 were correctly saved/restored, and the context of v8-v31 was corrupted. Now, v8-v31 are correctly saved/restored to avoid breaking the us...

FreeBSD Security Advisory - FreeBSD-SA-26:20.fusefs

FreeBSD Security Advisory - When a fusefs file system implements extended attributes, the kernel may send a FUSELISTXATTR message to the userspace daemon to retrieve the list of extended attributes for a given file. The FUSE protocol requires the daemon to return a packed list of NUL-terminated...

PT-2026-61366

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL pointer dereference can be triggered in the adreno get param function when userspace queries UBWC-related parameters on a2xx-a4xx Adreno drivers. This occurs because these hardwar...

Unity Linux 20.1060e / 20.1070e Security Update: openvswitch (UTSA-2026-017640)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017640 advisory. A vulnerability was found in openvswitch. A limitation in the implementation of userspace packet parsing can allow a malicious user to send a specially crafted packe...

SUSE CVE-2026-43265

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Ignore -EBUSY when checking nested events from vcpublock Ignore -EBUSY when checking nested events after exiting a blocking state while L2 is active, as exiting to userspace will generate a spurious userspace exit,...

EUVD-2025-209746

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: 8822b: Avoid WARNING in rtw8822bconfigtrxmode rtw8822bsetantenna can be called from userspace when the chip is powered off. In that case a WARNING is triggered in rtw8822bconfigtrxmode because trying to read the RF...

CVE-2026-43315

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Remove a user-triggerable WARN on nestedsvmloadcr3 succeeding Drop the WARN in svmsetnestedstate on nestedsvmloadcr3 failing as it is trivially easy to trigger from userspace by modifying CPUID after loading CR3. E.g...

kernel: out-of-bound read in memcpy_fromiovecend()

A flaw was found in the Linux kernel that allows the userspace to call memcpyfromiovecend and similar functions with a zero offset and buffer length. This can cause a read beyond the buffer boundaries flaw and, in certain cases, cause a memory access fault and a system halt by accessing invalid...

SUSE CVE-2026-43089

In the Linux kernel, the following vulnerability has been resolved: xfrmuser: fix info leak in buildmapping struct xfrmusersaid has a one-byte padding hole after the proto field, which ends up never getting set to zero before copying out to userspace. Fix that up by zeroing out the whole structur...
