Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1
Closing an event channel in the Linux kernel can lead to a deadlock. This occurs when the closure operation is performed in parallel with an unrelated Xen console action, and the handling of a Xen console interrupt occurs in a unprivileged guest. The closure of an event channel is triggered, for...

Astra Linux – Vulnerability in Linux, Linux 5.10
Rogue backends can cause Denial of Service DoS attacks on guests through high-frequency events. This CNA information record relates to multiple Common Vulnerabilities and Exposures CVEs; the text explains which aspects/vulnerabilities correspond to which CVEs. Xen allows for the execution of PV...
Astra Linux – Vulnerability in Xen
A issue was discovered in Xen versions 4.9 through 4.14.x. On the ARM architecture, a guest can control whether memory accesses bypass the cache. This means that Xen needs to ensure that all writes such as those during scrubbing have reached the memory before handing over the page to the guest...

In the Linux kernel, the following vulnerability has been resolved: 9p/xen: fixed the issue of releasing the IRQ twice. Kernel logs indicate that the IRQ was released twice. The correct device ID must be passed during the IRQ release process. Dominique: removed the confusing variable “reset” to 0...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: x86/amdnb: The function amdgetmmconfigrange uses rdmsrsafe, which should not be used without proper safeguards. Xen does not provide the MSRFAM10HMMIOCONFbase to all guests. This results in the following warning: Unchecked MSR...
Astra Linux – Vulnerability in Linux
A issue was discovered in the Linux kernel, specifically with versions up to 5.9.1, when used with Xen in versions up to 4.14.x. Users of guest operating systems may experience a denial of service where the host operating system hangs due to a high rate of events affecting dom0, also known as...
Astra Linux – Vulnerability in Linux
A issue was discovered in the Linux kernel versions 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur during batch hypercalls, where multiple operations are performed in a single hypercall. The success or failure of each operation is reported to the backend driver, and the...
