Linux Distros Unpatched Vulnerability : CVE-2023-53989

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - arm64: mm: fix VA-range sanity check Both createmappingnoalloc and updatemappingprot sanity-check their 'virt' parameter, but the check itself doesn't make much...

CVE-2025-68329

The CVE-2025-68329 entry documents a Linux kernel issue in tracing: when a VMA is split, the kernel could invoke ring_buffer_unmap multiple times (due to multiple vm_ops->close calls) while ring_buffer_map was called once, causing ring_buffer_unmap to return -ENODEV and triggering a WARN_ON. T...

CVE-2025-40336

Vulnerability summary: CVE-2025-40336 affects the Linux kernel DRM/GPU virtualization path (drm/gpusvm). The root cause is incorrect usage of hmm_pfn_to_map_order when a memory range partially covers a huge page (e.g., 2 MiB), which could lead to mapping memory outside the intended range. The pat...
