Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mshv: Fixed a use-after-free in the mshvmapusermemory error path. In the error path of mshvmapusermemory, calling vfree directly on the region causes the MMU notifier to remain registered. When the user space later unmaps the...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerability has been resolved: mshv: Fixed an infinite fault loop that occurred during GPA intercepts when permissions were denied. This issue prevents infinite fault loops when guests access memory regions without proper permissions. Currently,...

Astra Linux - уязвимость в linux-5.10

In the Linux kernel, the following vulnerabilities have been resolved: mshv: Error handling in mshvregionpin has been fixed. The current error handling has two issues: Firstly, the pinuserpagesfast function may return a short pin count less than the requested count but greater than zero when it...

SUSE CVE-2026-43348

In the Linux kernel, the following vulnerability has been resolved: mshvvtl: Fix vmemmapshift exceeding MAXFOLIOORDER When registering VTL0 memory via MSHVADDVTL0MEMORY, the kernel computes pgmap-vmemmapshift as the number of trailing zeros in the OR of startpfn and lastpfn, intending to use the...

CVE-2026-43348

A flaw was found in the Linux kernel's mshvvtl component. When registering VTL0 memory, an issue with memory mapping calculations can cause the system to trigger a warning and return an invalid argument error. This could lead to system instability or a denial of service DoS, preventing legitimate...

CVE-2026-43348 mshv_vtl: Fix vmemmap_shift exceeding MAX_FOLIO_ORDER

In the Linux kernel, the following vulnerability has been resolved: mshvvtl: Fix vmemmapshift exceeding MAXFOLIOORDER When registering VTL0 memory via MSHVADDVTL0MEMORY, the kernel computes pgmap-vmemmapshift as the number of trailing zeros in the OR of startpfn and lastpfn, intending to use the...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the calculation of vmemmapshift in mshvvtl. This calculation does not limit the value to...

Linux Distros Unpatched Vulnerability : CVE-2026-43348

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - mshvvtl: Fix vmemmapshift exceeding MAXFOLIOORDER When registering VTL0 memory via MSHVADDVTL0MEMORY, the kernel computes pgmap-vmemmapshift as the number of...

CVE-2026-43096

A flaw was found in the Linux kernel's mshv component. A malicious guest operating system could exploit this by attempting to write to read-only memory regions or execute code in non-executable regions. This can lead to an infinite fault loop, causing the virtual CPU vCPU to spin indefinitely and...

CVE-2026-43045

A flaw was found in the Linux kernel's mshv module. Incorrect error handling in the mshvregionpin function can lead to memory corruption. This occurs when the pinuserpagesfast operation returns a partial pin count, causing the system to use incompletely pinned memory regions. This issue can also...
