In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: Fix gem reference leak in validateinit On the ttmboreserve failure and "vma not found" error paths, the loop breaks without adding the looked-up object to any validate list, so the reference taken by drmgemobjectlook...

CVE-2026-98513 drm/nouveau: Fix runtime PM leak in nouveau_connector_detect()

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: Fix runtime PM leak in nouveauconnectordetect If nvifoutpedidget fails, nouveauconnectordetect returns early without dropping the runtime PM reference taken at the start of the function, keeping the device powered on...

CVE-2026-98513

The Linux kernel contains a vulnerability in the drm/nouveau driver within the nouveau_connector_detect() function. The root cause is a runtime PM leak occurring when nvif_outp_edid_get() fails, as the function returns early without dropping the runtime PM reference acquired at the start. This ca...

CVE-2026-98512

The Linux kernel contains a vulnerability in the drm/nouveau component where the nouveau_sched object is improperly freed using kfree() instead of kfree_rcu(). Because nouveau_sched_destroy() calls nouveau_sched_fini() before freeing the object, a finished fence exported to userspace via drm_sync...

CVE-2026-98512 drm/nouveau: RCU-free the scheduler-containing nouveau_sched

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: RCU-free the scheduler-containing nouveausched struct nouveausched embeds a struct drmgpuscheduler base. nouveauscheddestroy calls nouveauschedfini which does drmschedfini&sched-base and then frees the object with...

CVE-2026-98511

The Linux kernel 's nouveau driver contains a vulnerability in the nouveau_bo_pin_locked() function. When an already pinned Buffer Object (BO) is requested to be moved to an incompatible memory domain, the function correctly returns -EBUSY but fails to prevent a call to ttm_bo_pin() . Consequentl...

CVE-2026-98511 drm/nouveau: don't bump pin count on failed re-pin in nouveau_bo_pin_locked()

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau: don't bump pin count on failed re-pin in nouveaubopinlocked nouveaubopinlocked checks whether an already pinned BO is in a memory domain compatible with a new pin request. When the domains are incompatible, it sets...

CVE-2026-98510 drm/xe/vm: nuke PTs only after unlinking contested VMAs

In the Linux kernel, the following vulnerability has been resolved: drm/xe/vm: nuke PTs only after unlinking contested VMAs In xevmcloseandput, external-BO VMAs are queued on the contested list for deferred destruction via xevmadestroyunlocked. However, xevmptdestroy was previously invoked before...

CVE-2026-98510

The Linux kernel contains a race condition in the drm/xe/vm component. In xe_vm_close_and_put(), xe_vm_pt_destroy() was incorrectly invoked before processing contested VMAs, destroying vm->pt_root while VMAs remained linked to buffer objects. If a concurrent thread evicts a shared buffer objec...

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 ...

CVE-2026-98509 drm/virtio: fix memory leak of fence event on execbuffer failure

In the Linux kernel, the following vulnerability has been resolved: drm/virtio: fix memory leak of fence event on execbuffer failure virtiogpuexecbufferioctl reserves a DRM event with drmeventreserveinit when VIRTGPUEXECBUFRINGIDX selects a ring that userspace has enabled polling for...

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-2026-98508 drm/virtio: fix NULL pointer dereference on fence allocation failure

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-2026-98507

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-2026-98507 mm/rmap: fix missing barrier between anon_vma init and vma->anon_vma publish

In the Linux kernel, the following vulnerability has been resolved: mm/rmap: fix missing barrier between anonvma init and vma-anonvma publish On arm64 server, we find that a task trying to grab the anonvma lock triggers hungtask. INFO: task main:2354726 blocked for more than 120 seconds. Tainted:...

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...

CVE-2026-98506 mm/hugetlb: do not dissolve gigantic pages without runtime support

In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: do not dissolve gigantic pages without runtime support dissolvefreehugetlbfolio doesn't check hstateisgiganticnoruntimeh though removehugetlbfolio/ updateandfreehugetlbfolio silently bail for such folios, so it frees ...

CVE-2026-98505

The Linux kernel contains a bug in the damon_hugetlb_mkold() function where reading a page table entry (PTE) into a local variable to unset the accessed bit can lead to lost hardware updates . If hardware updates the same PTE in parallel, changes like dirty bits might be overwritten and lost. The...
