Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Forcibly leave nested virtualization mode when SMM state is toggled The nested virtualization mode is forcibly exited if the user space toggles the SMM state using KVMSETVCPUEVENTS or KVMSYNCX86EVENTS. If the user space...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerabilities have been resolved: net: openvswitch: Fixed a leak in nested actions. When parsing user-provided actions, the openvswitch module may dynamically allocate memory and store pointers in the internal copy of the actions. This memory must be freed whe...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the KVM’s AMD code, responsible for supporting SVM nested virtualization. The flaw occurs during the processing of the VMCB virtual machine control block provided by the L1 guest, which is used to spawn or handle a nested guest L2. Due to improper validation of the...

The package org.yaml:snakeyaml in versions 0 and earlier than 1.31 is vulnerable to Denial of Service DoS attacks due to a missing nested depth limitation in collections...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Check instead of asserting on nested TSC scaling support Check for nested TSC scaling support on nested SVM VMRUN instead of asserting that TSC scaling is exposed to L1 if L1’s MSRAMD64TSCRATIO has diverged from KVM’s...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: nSVM: fixed a potential NULL dereference during nested migration. It turns out that due to feedback from reviews and/or changes in relocation locations, I accidentally moved the call to nestedsvmloadcr3 too early, befor...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: ice: Fixed a potential NULL pointer dereference in the icebridgesetlink function. The icebridgesetlink function may encounter a NULL pointer dereference if nlmsgfindattr returns NULL, and brspec is dereferenced subsequently ...

Astra Linux – Vulnerability in Golang-1.19

Calling Decoder.Decode on a message that contains deeply nested structures can cause a panic due to stack exhaustion. This is a follow-up to CVE-2022-30635...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Warns when a triple fault assertion never “escapes” from L2 The warnings are removed because they perform a sanity check that ensures KVM never allows a triple fault in L2 to escape and end up in L1. In normal operation...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Ensure liveliness of nested VM-Enter fail tracepoint message Use the string machinery provided by the tracing subsystem to create a copy of the string literals used in the “nested VM-Enter failed” tracepoint. A complete...

Astra Linux – Vulnerability in Ruby 2.5

REXML is an XML toolkit for Ruby. The REXML gem before version 3.3.6 has a DoS vulnerability when it parses XMLs that contain many elements with the same local name attribute. If you need to parse untrusted XMLs using tree parser APIs like REXML::Document.new, you may be vulnerable to this...

Astra Linux – Vulnerability in Jackson-Databind

In FasterXML Jackson-Databind before version 2.13.4, resource exhaustion can occur due to the lack of a check in BeanDeserializer.deserializeFromArray, which prevents the use of deeply nested arrays. An application becomes vulnerable only with certain customized choices for deserialization...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Loads the TSC multiplier of L1 based on L1’s state, not L2’s state. When emulating a nested VM-Exit, the TSC multiplier of L1 is loaded if L1’s desired ratio does not match the current ratio. This does not occur if L1’...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: KVM: x86: Acquiring kvm-srcu when handling KVMSETVCPUEVENTS Acquire kvm-srcu when processing KVMSETVCPUEVENTS. When SMM mode is toggled, KVM will forcibly leave the nested VMX/SVM state. Leaving such a state also results in...
