kernel security update

The Linux Kernel, the operating system core itself.

Security Fix(es):

A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was found in the way user uses trace ring buffer in a specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.(CVE-2021-3679)

drivers/usb/host/max3421-hcd.c in the Linux kernel before 5.13.6 allows physically proximate attackers to cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain situations.(CVE-2021-38204)

drivers/net/ethernet/xilinx/xilinx_emaclite.c in the Linux kernel before 5.13.3 makes it easier for attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM pointer).(CVE-2021-38205)

net/netfilter/nf_conntrack_standalone.c in the Linux kernel before 5.12.2 allows observation of changes in any net namespace because these changes are leaked into all other net namespaces. This is related to the NF_SYSCTL_CT_MAX, NF_SYSCTL_CT_EXPECT_MAX, and NF_SYSCTL_CT_BUCKETS sysctls.(CVE-2021-38209)

fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for those servers to be unreachable during trunking detection.(CVE-2021-38199)

drivers/net/ethernet/xilinx/ll_temac_main.c in the Linux kernel before 5.12.13 allows remote attackers to cause a denial of service (buffer overflow and lockup) by sending heavy network traffic for about ten minutes.(CVE-2021-38207)

net/nfc/llcp_sock.c in the Linux kernel before 5.12.10 allows local unprivileged users to cause a denial of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure of a bind call.(CVE-2021-38208)

Security update for the Linux Kernel

The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

  • CVE-2021-3640: Fixed a Use-After-Free vulnerability in function sco_sock_sendmsg() in the bluetooth stack (bsc#1188172).
  • CVE-2021-3653: Missing validation of the int_ctl VMCB field and allows a malicious L1 guest to enable AVIC support for the L2 guest. (bsc#1189399).
  • CVE-2021-3656: Missing validation of the the virt_ext VMCB field and allows a malicious L1 guest to disable both VMLOAD/VMSAVE intercepts and VLS for the L2 guest (bsc#1189400).
  • CVE-2021-3679: A lack of CPU resource in tracing module functionality was found in the way user uses trace ring buffer in a specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service (bnc#1189057).
  • CVE-2021-3732: Mounting overlayfs inside an unprivileged user namespace can reveal files (bsc#1189706).
  • CVE-2021-3739: Fixed a NULL pointer dereference when deleting device by invalid id (bsc#1189832 ).
  • CVE-2021-3743: Fixed OOB Read in qrtr_endpoint_post (bsc#1189883).
  • CVE-2021-3753: Fixed race out-of-bounds in virtual terminal handling (bsc#1190025).
  • CVE-2021-38160: Data corruption or loss could be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size in drivers/char/virtio_console.c (bsc#1190117)
  • CVE-2021-38198: arch/x86/kvm/mmu/paging_tmpl.h incorrectly computes the access permissions of a shadow page, leading to a missing guest protection page fault (bnc#1189262).
  • CVE-2021-38204: drivers/usb/host/max3421-hcd.c allowed physically proximate attackers to cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain situations (bnc#1189291).
  • CVE-2021-38205: drivers/net/ethernet/xilinx/xilinx_emaclite.c made it easier for attackers to defeat an ASLR protection mechanism because it prints a kernel pointer (i.e., the real IOMEM pointer) (bnc#1189292).
  • CVE-2021-38207: drivers/net/ethernet/xilinx/ll_temac_main.c allowed remote attackers to cause a denial of service (buffer overflow and lockup) by sending heavy network traffic for about ten minutes (bnc#1189298).
  • CVE-2021-38166: Fixed an integer overflow and out-of-bounds write when many elements are placed in a single bucket in kernel/bpf/hashtab.c (bnc#1189233 ).
  • CVE-2021-38209: Fixed allowed observation of changes in any net namespace via net/netfilter/nf_conntrack_standalone.c (bnc#1189393).
  • CVE-2021-38206: Fixed NULL pointer dereference in the radiotap parser inside the mac80211 subsystem (bnc#1189296).
  • CVE-2021-34556: Fixed side-channel attack via a Speculative Store Bypass via unprivileged BPF program that could have obtain sensitive information from kernel memory (bsc#1188983).
  • CVE-2021-35477: Fixed BPF stack frame pointer which could have been abused to disclose content of arbitrary kernel memory (bsc#1188985).
  • CVE-2021-3759: Unaccounted ipc objects in Linux kernel could have lead to breaking memcg limits and DoS attacks (bsc#1190115).
  • CVE-2020-12770: Fixed sg_remove_request call in a certain failure cases (bsc#1171420).

The following non-security bugs were fixed:

  • ACPI: NFIT: Fix support for virtual SPA ranges (git-fixes).
  • ACPI: processor: Clean up acpi_processor_evaluate_cst() (bsc#1175543)
  • ACPI: processor: Export acpi_processor_evaluate_cst() (bsc#1175543)
  • ACPI: processor: Export function to claim _CST control (bsc#1175543)
  • ACPI: processor: Introduce acpi_processor_evaluate_cst() (bsc#1175543)
  • ACPI: processor: Make ACPI_PROCESSOR_CSTATE depend on ACPI_PROCESSOR (bsc#1175543)
  • ALSA: hda - fix the 'Capture Switch' value change notifications (git-fixes).
  • ALSA: hda/hdmi: Add quirk to force pin connectivity on NUC10 (git-fixes).
  • ALSA: hda/hdmi: fix max DP-MST dev_num for Intel TGL+ platforms (git-fixes).
  • ALSA: hda/hdmi: let new platforms assign the pcm slot dynamically (git-fixes).
