CVE-2026-62433

A flaw was found in Xen. The DMOP handling code in Xen does not properly validate the number of buffers provided by the caller. This oversight can lead to the system accessing uninitialized memory, potentially resulting in information disclosure or other unpredictable behavior. A malicious guest...

EUVD-2026-49938

A use-after-free condition exists in pglogical's worker signaling code, where a worker structure can be dereferenced after the underlying slot has been freed or recycled during normal worker lifecycle events. The condition is reachable during normal replication operation, including by a...

CVE-2026-48025 nebula-mesh: Decrypted CA private key persists in heap after signing

nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network. Prior to version 0.3.7, internal/pki/resolver.go:36-64 constructs a CAManager with the plaintext ed25519.PrivateKey after unwrapping via the master key; internal/pki/ca.go:13-16 stores it. Callers at...

CVE-2026-48025

CVE-2026-48025 (nebula-mesh) describes a memory-safety issue in versions prior to 0.3.7 where decrypted CA private keys (ed25519.PrivateKey) are constructed and stored in memory by the CAManager and not wiped after use. The problem arises when internal/pki/resolver.go constructs CAManager with th...

CVE-2026-62426

This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE. To manage the system, sysctl and platform operations are used by the control domain or a possible Xenstore domain. Some of these operations may not be executed in paralle...

CVE-2026-62428

When grant-copy operations are processed, the respective grant may or may not already be in use by another operation a mapping or another copy. For all copy operations the referenced guest frame is looked up. When another operation is already active for the grant the grant is "pinned", what is...

CVE-2026-62432

The EVTCHNOPexpandarray hypercall checks for whether FIFO event channels are enabled, but without holding the correct lock. It can race with EVTCHNOPreset, resulting in dereferencing a NULL pointer...

CVE-2026-62433

Parts of the DMOP handling code assumes the caller has provided the required number of buffers for the given operation without any checking being done. As a result, certain operations might access stack rubble as structures are possibly uninitialized...

CVE-2026-62432

CVE-2026-62432: The EVTCHNOP_expand_array hypercall in Xen signals a race with EVTCHNOP_reset when checking FIFO event channels, because the correct lock is not held, leading to potential dereference of a NULL pointer. Affected: Xen hypervisor interfaces referenced in the NVD entry and mirrored i...

CVE-2026-62426

CVE-2026-62426 concerns sysctl and platform-op locking in Xen environments. The issue arises from system-wide locks used for operations in control domain or Xenstore domain, where lock acquisition lacks fairness. With XSM/Flask enabled, some lock acquisitions can occur before permission checks, c...

sysctl and platform-op locks open to abuse

ISSUE DESCRIPTION To manage the system, sysctl and platform operations are used by the control domain or a possible Xenstore domain. Some of these operations may not be executed in parallel, so a system-wide lock each is used. The way those locks are acquired is, however, not providing any...
