kernel: vfio: Fix NULL pointer dereference caused by uninitialized group->iommufd

A NULL pointer dereference was found in the VFIO subsystem. When a VFIO group operation fails before group-iommufd is initialized, the cleanup path calls iommufdctxput with a NULL pointer, causing a kernel crash...

kernel: drm/virtio: Check whether transferred 2D BO is shmem

A flaw was found in the Linux kernel networking subsystem. Under certain conditions, a pointer may be dereferenced without proper validation, resulting in a NULL pointer dereference. An unprivileged local user could trigger this flaw by exercising the affected networking functionality, causing a...

kernel: drm/i915/perf: add sentinel to xehp_oa_b_counters

kernel: Linux kernel KVM: Denial of Service due to incorrect kvm_arm_init failure handling in finalize_pkvm

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for arm64 architectures. This vulnerability arises from a lack of synchronization between the finalizepkvm and kvmarminit initialization calls. A local attacker with low privileges could exploit this by triggering a scenario...
