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

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-2026-98504

The Linux kernel contains a vulnerability where the dynamic OF helpers of_pci_prop_bus_range() and of_pci_prop_intr_map() dereference pdev->subordinate without a prior check. This occurs when a bridge device (Type 1 header) lacks an allocated secondary bus, such as when bus numbers are unavail...

CVE-2026-98477

The Linux kernel contains a vulnerability in the perf/core component where __perf_pmu_sched_task() incorrectly passes a NULL pmu_ctx to pmu->sched_task(). This occurs because perf_pmu_sched_task() returns early when cpuctx->task_ctx is set, making cpc->task_epc null. The issue results in...

CVE-2026-98476 s390/cio: Fix NULL pointer dereference in ccw_device_get_util_str()

In the Linux kernel, the following vulnerability has been resolved: s390/cio: Fix NULL pointer dereference in ccwdevicegetutilstr The channel path registry entry associated with a CHPID may be removed while the subchannel's PMCW still references that CHPID. In this case, chpidtochp can return NUL...

CVE-2026-98476

The Linux kernel contains a NULL pointer dereference vulnerability in the s390/cio component within the ccw_device_get_util_str() function. This occurs because a channel path registry entry associated with a CHPID may be removed while a subchannel's PMCW still references that CHPID, causing chpid...
