Red Hat Security Advisory: kernel-rt security and bug fix update
hw: cpu: AMD CPUs may transiently execute beyond unconditional direct branch kernel: malicious data for FBIOPUT_VSCREENINFO ioctl may cause OOB write memory kernel: when setting font with malicious data by ioctl PIO_FONT, kernel will write memory out of bounds kernel: net: stmmac: fix tc flower deletion for VLAN priority Rx steering kernel: possible race condition in drivers/tty/tty_buffers.c kernel: use-after-free in ath9k_htc_probe_device() could cause an escalation of privileges kernel: KVM: NULL pointer dereference in kvm_mmu_invpcid_gva kernel: KVM: nVMX: missing IBPB when exiting from nested guest can lead to Spectre v2 attacks kernel: netfilter: nf_conntrack_irc message handling issue kernel: race condition in xfrm_probe_algs can lead to OOB read/write kernel: media: em28xx: initialize refcount before kref_get kernel: race condition in hugetlb_no_page() in mm/hugetlb.c kernel: memory leak in ipv6_renew_options() kernel: use-after-free caused by l2cap_reassemble_sdu() in net/bluetooth/l2cap_core.c kernel: data races around icsk->icsk_af_ops in do_ipv6_setsockopt kernel: data races around sk->sk_prot kernel: memory leak in l2cap_recv_acldata of the file net/bluetooth/l2cap_core.c kernel: denial of service in follow_page_pte in mm/gup.c due to poisoned pte entry kernel: use-after-free after failed devlink reload in devlink_param_get kernel: USB-accessible buffer overflow in brcmfmac kernel: Double-free in split_2MB_gtt_entry when function intel_gvt_dma_map_guest_page failed kernel: l2tp: missing lock when clearing sk_user_data can lead to NULL pointer dereference kernel: Recursive locking violation in usb-storage that can cause the kernel to deadlock kernel: igmp: use-after-free in ip_check_mc_rcu when opening and closing inet sockets kernel: Executable Space Protection Bypass kernel: Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option kernel: xfrm_expand_policies() in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice kernel: unmap_mapping_range() race with munmap() on VM_PFNMAP mappings leads to stale TLB entry kernel: TLB flush operations are mishandled in certain KVM_VCPU_PREEMPTED leading to guest malfunctioning kernel: Report vmalloc UAF in dvb-core/dmxdev kernel: u8 overflow problem in cfg80211_update_notlisted_nontrans() kernel: use-after-free related to leaf anon_vma double reuse kernel: use-after-free in bss_ref_get in net/wireless/scan.c kernel: BSS list corruption in cfg80211_add_nontrans_list in net/wireless/scan.c kernel: Denial of service in beacon protection for P2P-device kernel: memory corruption in usbmon driver kernel: NULL pointer dereference in traffic control subsystem kernel: scsi: mpt3sas: Fix use-after-free warning kernel: NULL pointer dereference in rawv6_push_pending_frames kernel: net/ulp: use-after-free in listening ULP sockets kernel: netfilter: NULL pointer dereference in nf_tables due to zeroed list head kernel: use-after-free caused by invalid pointer hostname in fs/cifs/connect.c kernel: Soft lockup occurred during __page_mapcount Kernel: NULL pointer dereference problem in sctp_sched_dequeue_common kernel: drm/virtio: improper return value check in virtio_gpu_object_shmem_init() kernel: slab-out-of-bounds read vulnerabilities in cbq_classify
