The 4.12.11 stable kernel update contains a number of important fixes across the tree.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Security fix for CVE-2017-13693, CVE-2017-13694, CVE-2017-13695.

This provides fixes for the user space ACPICA tools only. Any kernel updates are handled separately.

This update also includes the upgrade to the 20190209 version of the upstream source. 

---------------------------------------- 09 February 2018. Summary of changes for version 20180209 :

1) ACPICA kernel-resident subsystem :

Completed the final integration of the recent changes to Package Object handling and the module-level AML code support. This allows forward references from individual package elements when the package object is declared from within module-level code blocks. Provides compatibility with other ACPI implementations.

The new architecture for the AML module-level code has been completed and is now the default for the ACPICA code. This new architecture executes the module-level code in-line as the ACPI table is loaded/parsed instead of the previous architecture which deferred this code until after the table was fully loaded. This solves some ASL code ordering issues and provides compatibility with other ACPI implementations. At this time, there is an option to fallback to the earlier architecture, but this support is deprecated and is planned to be completely removed later this year.

Added a compile-time option to ignore AE_NOT_FOUND exceptions during resolution of named reference elements within Package objects.
Although this is potentially a serious problem, it can generate a lot of noise/errors on platforms whose firmware carries around a bunch of unused Package objects. To disable these errors, define ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS in the OS-specific header. All errors are always reported for ACPICA applications such as AcpiExec.

Fixed a regression related to the explicit type-conversion AML operators (ToXXXX). The regression was introduced early in 2017 but was not seen until recently because these operators are not fully supported by other ACPI implementations and are thus rarely used by firmware developers. The operators are defined by the ACPI specification to not implement the 'implicit result object conversion'. The regression incorrectly introduced this object conversion for the following explicit conversion operators :

  - ToInteger

  - ToString

  - ToBuffer

  - ToDecimalString

  - ToHexString

  - ToBCD

  - FromBCD

2) iASL Compiler/Disassembler and Tools :

iASL: Fixed a problem with the compiler constant folding feature as related to the ToXXXX explicit conversion operators. These operators do not support the 'implicit result object conversion' by definition.
Thus, ASL expressions that use these operators cannot be folded to a simple Store operator because Store implements the implicit conversion. This change uses the CopyObject operator for the ToXXXX operator folding instead. CopyObject is defined to not implement implicit result conversions and is thus appropriate for folding the ToXXXX operators.

iASL: Changed the severity of an error condition to a simple warning for the case where a symbol is declared both locally and as an external symbol. This accommodates existing ASL code.

AcpiExec: The -ep option to enable the new architecture for module-level code has been removed. It is replaced by the -dp option which instead has the opposite effect: it disables the new architecture (the default) and enables the legacy architecture. When the legacy code is removed in the future, the -dp option will be removed also.

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2077-1 advisory.

  - The acpi_ns_evaluate() function in drivers/acpi/acpica/nseval.c in the Linux kernel through 4.12.9 does     not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive     information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a     crafted ACPI table. (CVE-2017-13695)

  - In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rq's, which allows attackers to     cause a denial of service (infinite loop in update_blocked_averages) or possibly have unspecified other     impact by inducing a high load. (CVE-2018-20784)

  - An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel     through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM     ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the     location of kernel code and data and bypass kernel security protections such as KASLR. (CVE-2018-7755)

  - In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and     unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c. (CVE-2019-19377)

  - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in     crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4     bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat,     leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of     service. (CVE-2020-10769)

  - There is a flaw reported in the Linux kernel in versions before 5.9 in     drivers/gpu/drm/nouveau/nouveau_sgdma.c in nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The issue     results from the lack of validating the existence of an object prior to performing operations on the     object. An attacker with a local account with a root privilege, can leverage this vulnerability to     escalate privileges and execute code in the context of the kernel. (CVE-2021-20292)

  - A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.
    (CVE-2021-20321)

  - The fix for XSA-365 includes initialization of pointers such that subsequent cleanup code wouldn't use     uninitialized or stale values. This initialization went too far and may under certain conditions also     overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking     persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died,     leaving around zombie domains. All Linux versions having the fix for XSA-365 applied are vulnerable.
    XSA-365 was classified to affect versions back to at least 3.11. (CVE-2021-28688)

  - Insufficient control flow management for the Intel(R) 82599 Ethernet Controllers and Adapters may allow an     authenticated user to potentially enable denial of service via local access. (CVE-2021-33061)

  - 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)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)

  - A use-after-free flaw was found in fs/ext4/namei.c:dx_insert_block() in the Linux kernel's filesystem sub-     component. This flaw allows a local attacker with a user privilege to cause a denial of service.
    (CVE-2022-1184)

  - A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This     flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a     leak of internal kernel information. (CVE-2022-1353)

  - The root cause of this vulnerability is that the ioctl$DRM_IOCTL_MODE_DESTROY_DUMB can decrease refcount     of *drm_vgem_gem_object *(created in *vgem_gem_dumb_create*) concurrently, and *vgem_gem_dumb_create *will     access the freed drm_vgem_gem_object. (CVE-2022-1419)

  - A NULL pointer dereference flaw was found in the Linux kernel's X.25 set of standardized network protocols     functionality in the way a user terminates their session using a simulated Ethernet card and continued     usage of this connection. This flaw allows a local user to crash the system. (CVE-2022-1516)

  - Linux Kernel could allow a local attacker to execute arbitrary code on the system, caused by a concurrency     use-after-free flaw in the bad_flp_intr function. By executing a specially-crafted program, an attacker     could exploit this vulnerability to execute arbitrary code or cause a denial of service condition on the     system. (CVE-2022-1652)

  - A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged     user to gain root privileges. The bug allows to build several exploit primitives such as kernel address     information leak, arbitrary execution, etc. (CVE-2022-1729)

  - A flaw in Linux Kernel found in nfcmrvl_nci_unregister_dev() in drivers/nfc/nfcmrvl/main.c can lead to use     after free both read or write when non synchronized between cleanup routine and firmware download routine.
    (CVE-2022-1734)

  - A use-after-free flaw was found in the Linux kernel's NFC core functionality due to a race condition     between kobject creation and delete. This vulnerability allows a local attacker with CAP_NET_ADMIN     privilege to leak kernel information. (CVE-2022-1974)

  - There is a sleep-in-atomic bug in /net/nfc/netlink.c that allows an attacker to crash the Linux kernel by     simulating a nfc device from user-space. (CVE-2022-1975)

  - Incomplete cleanup of multi-core shared buffers for some Intel(R) Processors may allow an authenticated     user to potentially enable information disclosure via local access. (CVE-2022-21123)

  - Incomplete cleanup of microarchitectural fill buffers on some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2022-21125)

  - Incomplete cleanup in specific special register read operations for some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2022-21127)

  - Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2022-21166)

  - Improper input validation for some Intel(R) Processors may allow an authenticated user to potentially     cause a denial of service via local access. (CVE-2022-21180)

  - KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown.
    An attacker with access to a serial port could trigger the debugger so it is important that the debugger     respect the lockdown mode when/if it is triggered. (CVE-2022-21499)

  - usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double     free. (CVE-2022-28388)

  - ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.
    (CVE-2022-28390)

  - The Linux kernel before 5.17.2 mishandles seccomp permissions. The PTRACE_SEIZE code path allows attackers     to bypass intended restrictions on setting the PT_SUSPEND_SECCOMP flag. (CVE-2022-30594)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - Array index error in the tcm_vhost_make_tpg function in     drivers/vhost/scsi.c in the Linux kernel before 4.0     might allow guest OS users to cause a denial of service     (memory corruption) or possibly have unspecified other     impact via a crafted VHOST_SCSI_SET_ENDPOINT ioctl     call. NOTE: the affected function was renamed to     vhost_scsi_make_tpg before the vulnerability was     announced.(CVE-2015-4036)

  - The ecryptfs_privileged_open function in     fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3     allows local users to gain privileges or cause a denial     of service (stack memory consumption) via vectors     involving crafted mmap calls for /proc pathnames,     leading to recursive pagefault handling.(CVE-2016-1583)

  - It was found that SCSI driver in the Linux kernel can     improperly access userspace memory outside the provided     buffer. A local privileged attacker could potentially     use this flaw to expose information from the kernel     memory.(CVE-2017-13168)

  - The acpi_ds_create_operands() function in     drivers/acpi/acpica/dsutils.c in the Linux kernel     through 4.12.9 does not flush the operand cache and     causes a kernel stack dump, which allows local users to     obtain sensitive information from kernel memory and     bypass the KASLR protection mechanism (in the kernel     through 4.9) via a crafted ACPI table.(CVE-2017-13693)

  - The acpi_ps_complete_final_op() function in     drivers/acpi/acpica/psobject.c in the Linux kernel     through 4.12.9 does not flush the node and node_ext     caches and causes a kernel stack dump, which allows     local users to obtain sensitive information from kernel     memory and bypass the KASLR protection mechanism (in     the kernel through 4.9) via a crafted ACPI     table.(CVE-2017-13694)

  - The acpi_ns_evaluate() function in     drivers/acpi/acpica/nseval.c in the Linux kernel     through 4.12.9 does not flush the operand cache and     causes a kernel stack dump, which allows local users to     obtain sensitive information from kernel memory and     bypass the KASLR protection mechanism (in the kernel     through 4.9) via a crafted ACPI table.(CVE-2017-13695)

  - The XFS_IS_REALTIME_INODE macro in fs/xfs/xfs_linux.h     in the Linux kernel before 4.13.2 does not verify that     a filesystem has a realtime device, which allows local     users to cause a denial of service (NULL pointer     dereference and OOPS) via vectors related to setting an     RHINHERIT flag on a directory.(CVE-2017-14340)

  - The xfs_bmap_extents_to_btree function in     fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through     4.16.3 allows local users to cause a denial of service     (xfs_bmapi_write NULL pointer dereference) via a     crafted xfs image.(CVE-2018-10323)

  - A flaw was found in Linux kernel in the ext4 filesystem     code. A use-after-free is possible in     ext4_ext_remove_space() function when mounting and     operating a crafted ext4 image.(CVE-2018-10876)

  - A flaw was found in the Linux kernel ext4 filesystem.
    An out-of-bound access is possible in the     ext4_ext_drop_refs() function when operating on a     crafted ext4 filesystem image.(CVE-2018-10877)

  - The pcpu_embed_first_chunk function in mm/percpu.c in     the Linux kernel through 4.14.14 allows local users to     obtain sensitive address information by reading dmesg     data from a(CVE-2018-5995)

  - Memory leak in the irda_bind function in     net/irda/af_irda.c and later in     drivers/staging/irda/net/af_irda.c in the Linux kernel     before 4.17 allows local users to cause a denial of     service (memory consumption) by repeatedly binding an     AF_IRDA socket.(CVE-2018-6554)

  - A NULL pointer dereference was found in the     net/rds/rdma.c __rds_rdma_map() function in the Linux     kernel before 4.14.7 allowing local attackers to cause     a system panic and a denial-of-service, related to     RDS_GET_MR and RDS_GET_MR_FOR_DEST.(CVE-2018-7492)

  - ** DISPUTED ** Race condition in the     store_int_with_restart() function in     arch/x86/kernel/cpu/mcheck/mce.c in the Linux kernel     through 4.15.7 allows local users to cause a denial of     service (panic) by leveraging root access to write to     the check_interval file in a     /sys/devices/system/machinecheck/machinecheck<cpu     number> directory. NOTE: a third party has indicated     that this report is not security     relevant.(CVE-2018-7995)

  - Non-optimized code for key handling of shared futexes     was found in the Linux kernel in the form of unbounded     contention time due to the page lock for real-time     users. Before the fix, the page lock was an     unnecessarily heavy lock for the futex path that     protected too much. After the fix, the page lock is     only required in a specific corner case.(CVE-2018-9422)

  - A memory leak in the ccp_run_sha_cmd() function in     drivers/crypto/ccp/ccp-ops.c in the Linux kernel     through 5.3.9 allows attackers to cause a denial of     service (memory consumption), aka     CID-128c66429247.(CVE-2019-18808)

  - In the Linux kernel before 5.1, there is a memory leak     in __feat_register_sp() in net/dccp/feat.c, which may     cause denial of service, aka     CID-1d3ff0950e2b.(CVE-2019-20096)

  - An issue was discovered in the Linux kernel before     5.4.7. The prb_calc_retire_blk_tmo() function in     net/packet/af_packet.c can result in a denial of     service (CPU consumption and soft lockup) in a certain     failure case involving TPACKET_V3, aka     CID-b43d1f9f7067.(CVE-2019-20812)
