A 41-year-old former ransomware negotiator has been sentenced to nearly six years i.e., 70 months in prison in the U.S. for their role in conspiring with the now-defunct BlackCat ransomware operators to extort multiple victims and working with two other cybersecurity professionals to target...

kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM component. A local attacker with privileges on the host system could exploit a vulnerability in how KVM handles shadow page table entries SPTEs during memory-mapped I/O MMIO operations. By manipulating guest page table entrie...

CVE-2026-47262

A flaw was found in containerd, an open-source container runtime. A remote attacker could exploit this vulnerability by providing a maliciously crafted image. When a container is created from this image, it leads to uncontrolled resource consumption and memory exhaustion, causing the containerd...

CVE-2026-53322

A flaw was found in the Linux kernel's vfio/pci subsystem. During device shutdown, an improper order of operations in cleaning up Direct Memory Access Buffers DMABUFs before disabling the function creates a brief window. In this window, a device's Base Address Registers BARs could still be access...

CVE-2026-22078

CVE-2026-22078 concerns O+ Connect where an unauthenticated IPC service allows a local attacker to escalate privileges via the IPC channel. The root cause is lack of client authentication on the IPC interface, enabling external applications to perform sensitive actions with elevated privileges. T...

CVE-2026-22078 O+ Connect's lack of authentication for IPC channels led to a local privilege escalation vulnerability.

Because O+ Connect's IPC service does not authenticate clients, external applications can escalate privileges and perform sensitive actions through the IPC channel...

CVE-2026-53294

In the Linux kernel, the following vulnerability has been resolved: mailbox: mailbox-test: don't free the reused channel The RX channel can be aliased to the TX channel if it has a different MMIO. This special case needs to be handled when freeing the channels otherwise a double-free occurs...

PT-2026-51660

Name of the Vulnerable Software and Affected Versions GeoVision GV-I/O Box 4E version 2.09 Description OS command injection flaws exist in the libNetSetObj.so internal library, which is used to configure the network stack. A remote attacker can execute arbitrary commands by sending a specially...

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...

CVE-2026-0647

The 1794-AENTR adapter (Rockwell Automation FLEX I/O dual‑port EtherNet/IP) has an improper authentication flaw in its embedded web server. An unauthenticated attacker can change the device web interface password by sending a crafted HTTP GET request to a specific endpoint, without prior authenti...

CVE-2026-0646

The affected product is Rockwell Automation 1794-AENTR adapters (EtherNet/IP). The issue is a denial-of-service caused by improper memory handling of CIP protocol requests in the 1794-AENTR adapter, which can cause the device to fault and drop connections to its linked I/O modules, requiring a ma...

CVE-2026-52759

Ghidra before 12.1.1 contains an uncontrolled memory allocation vulnerability in the Mach-O binary parser that allows attackers to cause denial of service. An attacker can supply a crafted Mach-O binary with an arbitrarily large ncmds load command count value, forcing the parser to allocate...

CVE-2026-49495

Ghidra 10.2 before 12.1 contains an uncontrolled resource consumption vulnerability in ExportTrie.parseTrie that lacks cycle detection when traversing Mach-O binary export tries. A crafted Mach-O binary with circular references in the export trie causes unbounded queue growth and exponential stri...
