The vulnerability of the IBM Storage Protect data protection software platform for virtual environments lies in its authentication mechanisms’ deficiencies, which allow attackers to circumvent existing security restrictions.

The vulnerability of the IBM Storage Protect data protection software for virtual environments is related to deficiencies in the authentication mechanism. Exploiting this vulnerability allows a malicious actor to circumvent existing security restrictions from a remote location...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: KVM: arm64: Unconditionally save+flush host FPSIMD/SVE/SME state There are several issues with the way the hyp code lazily saves the host’s FPSIMD/SVE state. These include: The host SVE state is unexpectedly discarded due to...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Discard packets if the transport changes. If the socket has been de-assigned or assigned to another transport, we must discard any packets received because they are not expected and would cause issues when accessing...

Astra Linux – Vulnerability in Python 3.11

A vulnerability has been identified in the CPython venv module and CLI. This vulnerability arises from improper quoting of path names when creating a virtual environment. As a result, attackers can inject commands into the virtual environment “activation” scripts e.g., using “source...

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Acquiring SRCU in KVMGETMPSTATE to protect guest memory accesses Acquiring a lock on kvm-srcu when userspace is obtaining the MP state can lead to a severe edge case where processing APIC events, such as during pending...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ibmvnic: Do not reference skb after sending it to VIOS. Previously, after successfully flushing the xmit buffer to VIOS, the txbytes stat was incremented by the length of the skb. It is invalid to access the skb memory after...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: hisiaccvfiopci: bugfix for live migration function without VF device driver If the VF device driver is not loaded in the Guest OS and we attempt to perform device data migration, the address of the migrated data will be NULL. The...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Forcing the SMM mode to remain active during SHUTDOWN interception Previously, the commit ed129ec9057f “KVM: x86: forcing the nested mode to remain active during vCPU reset” addressed an issue where a triple fault...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: drm/xe/vf: Do not attempt to trigger a full GT reset if there is a VF involved. VFs do not have access to the GDRST0x941c register, which is used by the driver to reset the GT. Attempt to trigger a reset using debugfs: bash $ cat...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: net: dsa: clean up FDB, MDB, and VLAN entries after unbinding. As explained in many places, such as commit b117e1e8a86d “net: dsa: delete dsalegacyfdbadd and dsalegacyfdbdel”, DSA is written under the assumption that higher layer...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerabilities have been resolved: ice: Fixed the issue of deinitializing VFs in an erroneous path. If iceenavfs fails after calling icecreatevfEntries, it frees all VFs without removing them from the PF-VF mailbox list, resulting in list corruption. Reproducin...
