description: kernel: malicious data for FBIOPUT_VSCREENINFO ioctl may cause OOB write memory kernel: KVM: nVMX: missing IBPB when exiting from nested guest can lead to Spectre v2 attacks kernel: media: em28xx: initialize refcount before kref_get kernel: use-after-free after failed devlink reload in devlink_param_get kernel: net/packet: slab-out-of-bounds access in packet_recvmsg() hw: cpu: arm64: Spectre-BHB kernel: use-after-free due to improper update of reference count in net/sched/cls_u32.c kernel: vmwgfx: integer overflow in vmwgfx_execbuf.c kernel: vmwgfx: NULL pointer dereference in vmw_cmd_dx_define_query kernel: vmwgfx: use-after-free in vmw_cmd_res_check kernel: vmwgfx: use-after-free in vmw_execbuf_tie_context kernel: sctp: fail if no bound addresses can be used for a given scope kernel: GSM multiplexing race condition leads to privilege escalation kernel: Out of boundary write in perf_read_group() as result of overflow a perf_event's read_size kernel: KVM: nVMX: missing consistency checks for CR0 and CR4 kernel: blocking operation in dvb_frontend_get_event and wait_event_interruptible kernel: use-after-free in amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c kernel: nf_tables: use-after-free vulnerability in the nft_verdict_init() function
