CVE-2026-98509

A memory leak vulnerability exists in the Linux kernel 's drm/virtio component. The issue occurs in virtio_gpu_execbuffer_ioctl() when a DRM event is reserved via drm_event_reserve_init() for a ring enabled for polling. Because virtio_gpu_init_submit() performs this reservation before processing ...

In the Linux kernel, the following vulnerability has been resolved: drm/virtio: fix NULL pointer dereference on fence allocation failure virtiogpufencealloc can fail due to memory pressure and return NULL, but its caller like virtiogpuinitsubmit never checks it. Later, virtiogpuinitsubmit passes...

CVE-2026-98508

The Linux kernel contains a vulnerability in the drm/virtio component where a NULL pointer dereference occurs during fence allocation failures. Specifically, the function virtio_gpu_fence_alloc() can return NULL under memory pressure, but the caller virtio_gpu_init_submit() fails to validate this...

CVE-2026-98507

The Linux kernel is susceptible to a race condition in the mm/rmap component on arm64 servers. The vulnerability exists because a missing memory barrier between the initialization of anon_vma and its publication to vma->anon_vma allows for memory reordering. Specifically, a thread can observe ...

CVE-2026-98506

The Linux kernel contains a vulnerability in the mm/hugetlb component where the dissolve_free_hugetlb_folio() function fails to check hstate_is_gigantic_no_runtime(h). Because remove_hugetlb_folio() and update_and_free_hugetlb_folio() silently bail for such folios, the system may free a folio tha...
