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...
PT-2026-61489
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the KVM SVM implementation for Hygon Family 18h CPUs. Due to a hardware erratum, the system may read a stale IsRunning=1 bit during ICR write emulation. This causes a...

libusb: libusb: Denial of Service via malformed USB descriptor
A flaw was found in libusb. This out-of-bounds read vulnerability allows a local attacker, particularly in virtualized environments utilizing USB passthrough, to trigger a denial of service. By providing a malformed USB descriptor, the attacker can cause the software to read beyond its allocated...
libusb: libusb: Denial of Service via malformed USB configuration descriptor
A flaw was found in libusb. An attacker can provide a specially crafted Universal Serial Bus USB configuration descriptor to applications using libusb. This malformed descriptor can lead to a null pointer dereference, causing the application to crash and resulting in a denial of service. This...
