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...

Linux Distros Unpatched Vulnerability : CVE-2026-53359

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - KVM: x86: Fix shadow paging use-after-free due to unexpected role Commit 0cb2af2ea66ad KVM: x86: Fix shadow paging use-after-free due to unexpected GFN fixed a...

kernel: RDMA/rxe: Fix double free in rxe_srq_from_init

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the rxe driver. An error in the rxesrqfrominit function's memory management can lead to a double free vulnerability. This occurs when an attempt to copy data to user space fails, causing the sam...
