CVE-2026-42487

CVE-2026-42487 concerns the Xen hypervisor’s handling of x86 HVM I/O port list traversal. The root cause stated in the sources is that traversal of the linked list used for guest I/O port accesses requires synchronization with updates to the translation/mapping (XEN_DOMCTL_ioport_mapping), but th...

CVE-2026-42487 x86 HVM I/O port list traversal

HVM guest I/O port accesses are subject to either emulation or at least translation. Translations are managed by the device model via XENDOMCTLioportmapping, and hence the linked list used may changed at any time. Traversal of those lists while handling guest I/O port accesses therefore needs...

Authentication Bypass

Spring Web Services is vulnerable to Authentication Bypass. The vulnerability is due to X509AuthenticationProvider issuing a fully authenticated X509AuthenticationToken based solely on certificate-to-user mapping, without enforcing standard account status checks such as disabled, locked, expired,...

On Xtensa targets with CONFIGUSERSPACE and CONFIGXTENSAMMU, the page-table code arch/xtensa/core/ptables.c maintains a global list, xtensadomainlist, of active memory domains using a list node embedded inside the caller-owned struct kmemdomain. When a domain is destroyed via kmemdomaindeinit -...

CVE-2026-10635 Dangling memory-domain pointer (use-after-free) in Xtensa MMU page-table code on memory-domain de-init

On Xtensa targets with CONFIGUSERSPACE and CONFIGXTENSAMMU, the page-table code arch/xtensa/core/ptables.c maintains a global list, xtensadomainlist, of active memory domains using a list node embedded inside the caller-owned struct kmemdomain. When a domain is destroyed via kmemdomaindeinit -...

CVE-2026-10635

CVE-2026-10635 affects Zephyr v4.4.0 on Xtensa targets with CONFIG_USERSPACE and CONFIG_XTENSA_MMU. The bug arises when destroying a memory domain via k_mem_domain_deinit(): the page-table code keeps a global xtensa_domain_list entry for the domain, but the node is not removed, leaving a dangling...

PT-2026-49810

In OSMMapPMRGeneric of pmr os.c, there is a possible way to leverage a system call to system call to maliciously expand the VMA out of bounds due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not...

EEF-CVE-2026-48599 Authorization bypass via path binding override in elixir-grpc/grpc HTTP transcoding

Summary Authorization Bypass Through User-Controlled Key vulnerability in elixir-grpc grpc allows authenticated attackers to access or modify resources belonging to other users by smuggling a conflicting value for any path-bound field via the query string or request body. In...

Inefficient Algorithmic Complexity

Overview js-yaml is a human-friendly data serialization language. Affected versions of this package are vulnerable to Inefficient Algorithmic Complexity in the storeMappingPair function in loader.js when handling repeated aliases in merge sequences. An attacker can exhaust CPU resources and...

@babel/core: Arbitrary File Read via sourceMappingURL Comment

Impact Using @babel/core to compile maliciously crafted code can allow ab attacker to read any source map from the system that is running Babel, if these conditions are all true: - the attacker controls the input source code - the attacker can read the output source code - the attacker knows the...

Beyond the Score: Using AI to Translate CVEs into Real-World Business Risk

Security leaders rarely struggle to gather data, but they often struggle to turn that data into something clear and meaningful for the business. In a typical week, a CISO might receive a report listing hundreds or even thousands of vulnerabilities, most of them accompanied by CVSS scores that mak...
