CVE-2026-99155

A flaw was found in the Linux kernel's Xen virtual Small Computer System Interface SCSI frontend driver. This vulnerability allows a malicious or compromised backend service to trigger a Denial of Service DoS by crashing the guest virtual machine. The issue occurs when the driver processes a...

CVE-2026-99057

A flaw was found in the Linux kernel's Xen network frontend driver. When processing a network response chain that exceeds the allocated buffer capacity, an error handling failure prevents the socket buffer and associated memory pages from being freed. A malicious or compromised backend can exploi...

CVE-2026-98375

A flaw was found in the Linux kernel's Xen network frontend driver. This vulnerability allows a malicious host backend to cause a Denial of Service DoS by transmitting incoming network packets with an incomplete Ethernet header. Because the driver fails to verify that incoming packet buffers meet...

CVE-2025-47314

The CVE-2025-47314 issue affects an Automotive Software platform based on QNX used in Qualcomm chipsets. The root cause reported is memory corruption encountered when processing data sent by the FE driver. The vulnerability is described with a CVSSv3.1 base score of 7.8 (HIGH) and an attack vecto...

PT-2025-39277

Name of the Vulnerable Software and Affected Versions Affected versions not specified Description A memory corruption issue exists when processing data received from the FE driver. This can lead to unpredictable behavior or potential system compromise. Recommendations At the moment, there is no...

Linux Kernel Buffer Overflow Vulnerability

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that originates from an out-of-bounds write error in the rtl2832pidfilter function in the drivers:media:dvb-frontends/rtl2832...

USN-5644-1: Linux kernel (GCP) vulnerabilities

It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2021-33655 Duoming...

Updated kernel packages fix security issues and possible filesystem corruption

This kernel update is based on upstream 5.10.20 and fixes at least the following security issues: A NULL pointer dereference flaw was found in the Linux kernel's GPU Nouveau driver functionality in versions prior to 5.12-rc1 in the way the user calls ioctl DRMIOCTLNOUVEAUCHANNELALLOC. This flaw...

Design/Logic Flaw

An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the netback driver lacks necessary treatment of errors such as failed memory allocations as a result of changes to the handling of grant mapping errors. A host OS denial of service may occur during...

A host OS denial of service may occur during...

Linux: backends treating grant mapping errors as bugs

ISSUE DESCRIPTION Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests, like out of memory conditions, it isn't correct to assume so. Memory allocations potentially causing such...
