title: Red Hat Security Advisory: kernel-rt security and bug fix update
description: kernel: avoid cyclic entity chains due to malformed USB descriptors kernel: integer overflow in k_ascii() in drivers/tty/vt/keyboard.c kernel: use-after-free in nouveau kernel module kernel: out-of-bounds read in bpf_skb_change_head() of filter.c due to a use-after-free kernel: joydev: zero size passed to joydev_handle_JSIOCSBTNMAP() kernel: reading /proc/sysvipc/shm does not scale with large shared memory segment counts kernel: out-of-bound Read in qrtr_endpoint_post in net/qrtr/qrtr.c kernel: crypto: ccp - fix resource leaks in ccp_run_aes_gcm_cmd() kernel: possible use-after-free in bluetooth module kernel: unaccounted ipc objects in Linux kernel lead to breaking memcg limits and DoS attacks kernel: DoS in ccp_run_aes_gcm_cmd() function kernel: sctp: Invalid chunks may be used to remotely remove existing associations kernel: lack of port sanity checking in natd and netfilter leads to exploit of OpenVPN clients kernel: stack information leak in infiniband RDMA kernel: possible leak or coruption of data residing on hugetlbfs kernel: security regression for CVE-2018-13405 kernel: fget: check that the fd still exists after getting a ref to it kernel: KVM: SVM: out-of-bounds read/write in sev_es_string_io kernel: Buffer overwrite in decode_nfs_fh function kernel: cgroup: Use open-time creds and namespace for migration perm checks kernel: Race condition in races in sk_peer_pid and sk_peer_cred accesses kernel: new DNS Cache Poisoning Attack based on ICMP fragment needed packets replies hw: cpu: LFENCE/JMP Mitigation Update for CVE-2017-5715 kernel: Local privilege escalation due to incorrect BPF JIT branch displacement computation kernel: use-after-free in hso_free_net_device() in drivers/net/usb/hso.c kernel: eBPF multiplication integer overflow in prealloc_elems_and_freelist() in kernel/bpf/stackmap.c leads to out-of-bounds write kernel: Heap buffer overflow in firedtv driver kernel: an array-index-out-bounds in detach_capi_ctr in drivers/isdn/capi/kcapi.c kernel: mwifiex_usb_recv() in drivers/net/wireless/marvell/mwifiex/usb.c allows an attacker to cause DoS via crafted USB device kernel: use-after-free in the TEE subsystem kernel: information leak in the IPv6 implementation kernel: information leak in the IPv4 implementation kernel: dm: fix mempool NULL pointer race when completing IO kernel: tcp: fix page frag corruption on page fault kernel: ethtool: ioctl: fix potential NULL deref in ethtool_set_coalesce() kernel: mptcp: fix deadlock in __mptcp_push_pending() kernel: RDMA/irdma: Fix a user-after-free in add_pble_prm hw: cpu: intel: Branch History Injection (BHI) hw: cpu: intel: Intra-Mode BTI kernel: Local denial of service in bond_ipsec_add_sa kernel: DoS in sctp_addto_chunk in net/sctp/sm_make_chunk.c kernel: information leak in copy_page_to_iter() in iov_iter.c kernel: FUSE allows UAF reads of write() buffers, allowing theft of (partial) /etc/shadow hashes kernel: RDMA/uverbs: NULL pointer dereference in uapi_finalize() kernel: sfc_ef100: NULL pointer dereference in ef100_update_stats() kernel: drm/amdkfd: NULL pointer dereference in kfd_parse_subtype_iolink() kernel: Copy_from_user on 64-bit versions may leak kernel information kernel: IPv6: panic in fib6_rule_suppress when fib6_rule_lookup fails
