The expected behavior is to...

CVE-2025-40265

CVE-2025-40265 affects the Linux kernel vfat filesystem code. A missing return-value check of sb_min_blocksize() could trigger a kernel panic during NVMe/qemu emulation when mounting a vfat filesystem with 8 KiB logical/physical block sizes and no format. The vulnerability is addressed by the ref...

CVE-2025-40230

CVE-2025-40230 covers a Linux kernel issue where memory error injections on a Transparent Huge Page (THP) mapped to userspace could trigger a kernel panic. The root cause: during THP splitting, the kernel reads THP pages to identify zeropage mappings while a memory failure is being handled, which...

CVE-2025-40225

CVE-2025-40225 affects the Linux kernel panthor DRM/GPU virtualization path. The issue occurs when userspace partially unmaps a GPU virtual address region (drm_gpuva) via VM_BIND, which can trigger a NULL pointer dereference in the panthor_gpuva_sm_step_remap path and cause a kernel panic. The ro...
