Title:Security update for the Linux Kernel (Important)
Description:

The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive various security and bugfixes.



The following security bugs were fixed:

- CVE-2020-36312: Fixed an issue in virt/kvm/kvm_main.c that had a kvm_io_bus_unregister_dev memory leak upon a kmalloc failure (bnc#1184509). - CVE-2021-29650: Fixed an issue inside the netfilter subsystem that allowed attackers to cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h lack a full memory barrier upon the assignment of a new table value (bnc#1184208). - CVE-2020-27673: Fixed an issue in Xen where a guest OS users could have caused a denial of service (host OS hang) via a high rate of events to dom0 (bnc#1177411, bnc#1184583). - CVE-2021-29154: Fixed BPF JIT compilers that allowed to execute arbitrary code within the kernel context (bnc#1184391). - CVE-2020-25673: Fixed NFC endless loops caused by repeated llcp_sock_connect() (bsc#1178181). - CVE-2020-25672: Fixed NFC memory leak in llcp_sock_connect() (bsc#1178181). - CVE-2020-25671: Fixed NFC refcount leak in llcp_sock_connect() (bsc#1178181). - CVE-2020-25670: Fixed NFC refcount leak in llcp_sock_bind() (bsc#1178181). - CVE-2021-28950: Fixed an issue in fs/fuse/fuse_i.h where a 'stall on CPU' could have occured because a retry loop continually finds the same bad inode (bnc#1184194, bnc#1184211). - CVE-2020-36322: Fixed an issue inside the FUSE filesystem implementation where fuse_do_getattr() calls make_bad_inode() in inappropriate situations, could have caused a system crash. NOTE: the original fix for this vulnerability was incomplete, and its incompleteness is tracked as CVE-2021-28950 (bnc#1184211). - CVE-2021-30002: Fixed a memory leak issue when a webcam device exists (bnc#1184120). - CVE-2021-3483: Fixed a use-after-free bug in nosy_ioctl() (bsc#1184393). - CVE-2021-20219: Fixed a denial of service vulnerability in drivers/tty/n_tty.c of the Linux kernel. In this flaw a local attacker with a normal user privilege could have delayed the loop and cause a threat to the system availability (bnc#1184397). - CVE-2021-29265: Fixed an issue in usbip_sockfd_store in drivers/usb/usbip/stub_dev.c that allowed attackers to cause a denial of service (GPF) because the stub-up sequence has race conditions during an update of the local and shared status (bnc#1184167). - CVE-2021-29264: Fixed an issue in drivers/net/ethernet/freescale/gianfar.c in the Freescale Gianfar Ethernet driver that allowed attackers to cause a system crash because a negative fragment size is calculated in situations involving an rx queue overrun when jumbo packets are used and NAPI is enabled (bnc#1184168). - CVE-2021-28972: Fixed an issue in drivers/pci/hotplug/rpadlpar_sysfs.c where the RPA PCI Hotplug driver had a user-tolerable buffer overflow when writing a new device name to the driver from userspace, allowing userspace to write data to the kernel stack frame directly. This occurs because add_slot_store and remove_slot_store mishandle drc_name '\0' termination (bnc#1184198). - CVE-2021-28660: Fixed rtw_wx_set_scan in drivers/staging/rtl8188eu/os_dep/ioctl_linux.c that allowed writing beyond the end of the ssid array (bnc#1183593). - CVE-2020-0433: Fixed blk_mq_queue_tag_busy_iter of blk-mq-tag.c, where a possible use after free due to improper locking could have happened. This could have led to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation (bnc#1176720). - CVE-2021-28038: Fixed an issue with Xen PV. A certain part of the netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931 (bnc#1183022, bnc#1183069). - CVE-2021-27365: Fixed an issue inside the iSCSI data structures that does not have appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a Netlink message (bnc#1182715). - CVE-2021-27363: Fixed an issue with a kernel pointer leak that could have been used to determine the address of the iscsi_transport structure. When an iSCSI transport is registered with the iSCSI subsystem, the transport's handle is available to unprivileged users via the sysfs file system, at /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When read, the show_transport_handle function (in drivers/scsi/scsi_transport_iscsi.c) is called, which leaks the handle. This handle is actually the pointer to an iscsi_transport struct in the kernel module's global variables (bnc#1182716). - CVE-2021-27364: Fixed an issue in drivers/scsi/scsi_transport_iscsi.c where an unprivileged user can craft Netlink messages (bnc#1182717). - CVE-2020-1749: Fixed a flaw inside of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality (bnc#1165629).

The following non-security bugs were fixed:

- bluetooth: eliminate the potential race condition when removing the HCI controller (bsc#1184611). - Btrfs: add missing extents release on file extent cluster relocation error (bsc#1159483). - btrfs: change timing for qgroup reserved space for ordered extents to fix reserved space leak (bsc#1172247). - btrfs: Cleanup try_flush_qgroup (bsc#1182047). - btrfs: Do not flush from btrfs_delayed_inode_reserve_metadata (bsc#1182047). - btrfs: drop unused parameter qgroup_reserved (bsc#1182261). - btrfs: fix qgroup data rsv leak caused by falloc failure (bsc#1182261). - btrfs: fix qgroup_free wrong num_bytes in btrfs_subvolume_reserve_metadata (bsc#1182261). - btrfs: Free correct amount of space in btrfs_delayed_inode_reserve_metadata (bsc#1182047). - btrfs: inode: move qgroup reserved space release to the callers of insert_reserved_file_extent() (bsc#1172247). - btrfs: inode: refactor the parameters of insert_reserved_file_extent() (bsc#1172247). - btrfs: make btrfs_ordered_extent naming consistent with btrfs_file_extent_item (bsc#1172247). - btrfs: qgroup: allow to unreserve range without releasing other ranges (bsc#1120163). - btrfs: qgroup: Always free PREALLOC META reserve in btrfs_delalloc_release_extents() (bsc#1155179). - btrfs: qgroup: do not commit transaction when we already hold the handle (bsc#1178634). - btrfs: qgroup: Do not hold qgroup_ioctl_lock in btrfs_qgroup_inherit() (bsc#1165823). - btrfs: qgroup: do not try to wait flushing if we're already holding a transaction (bsc#1179575). - btrfs: qgroup: Fix a bug that prevents qgroup to be re-enabled after disable (bsc#1172247). - btrfs: qgroup: fix data leak caused by race between writeback and truncate (bsc#1172247). - btrfs: qgroup: fix qgroup meta rsv leak for subvolume operations (bsc#1177856). - btrfs: qgroup: Fix reserved data space leak if we have multiple reserve calls (bsc#1152975). - btrfs: qgroup: Fix the wrong target io_tree when freeing reserved data space (bsc#1152974). - btrfs: qgroup: fix wrong qgroup metadata reserve for delayed inode (bsc#1177855). - btrfs: qgroup: mark qgroup inconsistent if we're inherting snapshot to a new qgroup (bsc#1165823). - btrfs: qgroup: remove ASYNC_COMMIT mechanism in favor of reserve retry-after-EDQUOT (bsc#1120163). - btrfs: qgroup: try to flush qgroup space when we get -EDQUOT (bsc#1120163). - btrfs: remove unused parameter from btrfs_subvolume_release_metadata (bsc#1182261). - btrfs: tracepoints: Fix bad entry members of qgroup events (bsc#1155186). - btrfs: tracepoints: Fix wrong parameter order for qgroup events (bsc#1155184). - ext4: check journal inode extents more carefully (bsc#1173485). - ext4: do not allow overlapping system zones (bsc#1173485). - ext4: handle error of ext4_setup_system_zone() on remount (bsc#1173485). - hv_netvsc: remove ndo_poll_controller (bsc#1185248). - KVM: Add proper lockdep assertion in I/O bus unregister (bsc#1185555). - KVM: Destroy I/O bus devices on unregister failure _after_ sync'ing SRCU (bsc#1185556). - KVM: Stop looking for coalesced MMIO zones if the bus is destroyed (bsc#1185557). - xen-netback: respect gnttab_map_refs()'s return value (bsc#1183022 XSA-367). - Xen/gnttab: handle p2m update errors on a per-slot basis (bsc#1183022 XSA-367).
