The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0762-1 advisory.

  - An issue was discovered in fs/gfs2/rgrp.c in the Linux kernel before 4.8. A use-after-free is caused by     the functions gfs2_clear_rgrpd and read_rindex_entry. (CVE-2016-10905)

  - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:
    Upstream kernel (CVE-2021-0920)

  - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may     allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)

  - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an     authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

  - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the     kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups     v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
    (CVE-2022-0492)

  - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way     user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw     to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)

  - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the     O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a     regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file     descriptor. (CVE-2022-24448)

An update of the linux package has been released.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:

  - The bnep_sock_ioctl function in     net/bluetooth/bnep/sock.c in the Linux kernel before     2.6.39 does not ensure that a certain device field ends     with a '\0' character, which allows local users to     obtain potentially sensitive information from kernel     stack memory, or cause a denial of service (BUG and     system crash), via a BNEPCONNADD command.
    (CVE-2011-1079)

  - An issue was discovered in fs/gfs2/rgrp.c in the Linux     kernel before 4.8. A use-after-free is caused by the     functions gfs2_clear_rgrpd and read_rindex_entry.
    (CVE-2016-10905)

  - An issue was discovered in     drivers/scsi/aacraid/commctrl.c in the Linux kernel     before 4.13. There is potential exposure of kernel stack     memory because aac_get_hba_info does not initialize the     hbainfo structure. (CVE-2017-18550)

  - An issue was discovered in the Linux kernel before     4.14.11. A double free may be caused by the function     allocate_trace_buffer in the file kernel/trace/trace.c.
    (CVE-2017-18595)

  - Improper invalidation for page table updates by a     virtual guest operating system for multiple Intel(R)     Processors may allow an authenticated user to     potentially enable denial of service of the host system     via local access. (CVE-2018-12207)

  - An issue was discovered in the Linux kernel before 4.20.
    There is a race condition in smp_task_timedout() and     smp_task_done() in drivers/scsi/libsas/sas_expander.c,     leading to a use-after-free. (CVE-2018-20836)

  - An issue was discovered in the Linux kernel before     4.18.7. In create_qp_common in     drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp     was never initialized, resulting in a leak of stack     memory to userspace. (CVE-2018-20855)

  - An issue was discovered in fs/xfs/xfs_super.c in the     Linux kernel before 4.18. A use after free exists,     related to xfs_fs_fill_super failure. (CVE-2018-20976)

  - In the tun subsystem in the Linux kernel before 4.13.14,     dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a     denial of service (NULL pointer dereference and panic)     via an ioctl(TUNSETIFF) call with a dev name containing     a / character. This is similar to CVE-2013-4343.
    (CVE-2018-7191)

  - Insufficient access control in subsystem for Intel (R)     processor graphics in 6th, 7th, 8th and 9th Generation     Intel(R) Core(TM) Processor Families; Intel(R)     Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900     Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6 and E-2100     Processor Families may allow an authenticated user to     potentially enable denial of service via local access.
    (CVE-2019-0154)

  - Insufficient access control in a subsystem for Intel (R)     processor graphics in 6th, 7th, 8th and 9th Generation     Intel(R) Core(TM) Processor Families; Intel(R)     Pentium(R) Processor J, N, Silver and Gold Series;
    Intel(R) Celeron(R) Processor J, N, G3900 and G4900     Series; Intel(R) Atom(R) Processor A and E3900 Series;
    Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and     E-2200 Processor Families; Intel(R) Graphics Driver for     Windows before 26.20.100.6813 (DCH) or 26.20.100.6812     and before 21.20.x.5077 (aka15.45.5077), i915 Linux     Driver for Intel(R) Processor Graphics before versions     5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201 may     allow an authenticated user to potentially enable     escalation of privilege via local access.
    (CVE-2019-0155)

  - TSX Asynchronous Abort condition on some CPUs utilizing     speculative execution may allow an authenticated user to     potentially enable information disclosure via a side     channel with local access. (CVE-2019-11135)

  - The Linux kernel before 5.1-rc5 allows page->_refcount     reference count overflow, with resultant use-after-free     issues, if about 140 GiB of RAM exists. This is related     to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h,     kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - The do_hidp_sock_ioctl function in     net/bluetooth/hidp/sock.c in the Linux kernel before     5.0.15 allows a local user to obtain potentially     sensitive information from kernel stack memory via a     HIDPCONNADD command, because a name field may not end     with a '\0' character. (CVE-2019-11884)

  - ** DISPUTED ** An issue was discovered in     drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr,     which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is     handled sufficiently and there is no chance for a NULL     pointer dereference. (CVE-2019-12382)

  - An issue was discovered in the Linux kernel before     5.2.3. There is a use-after-free caused by a malicious     USB device in the drivers/media/usb/dvb-usb/dvb-usb-     init.c driver. (CVE-2019-15213)

  - An issue was discovered in xfs_setattr_nonsize in     fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS     partially wedges when a chgrp fails on account of being     out of disk quota. xfs_setattr_nonsize is failing to     unlock the ILOCK after the xfs_qm_vop_chown_reserve call     fails. This is primarily a local DoS attack vector, but     it might result as well in remote DoS if the XFS     filesystem is exported for instance via NFS.
    (CVE-2019-15538)

  - In the Linux kernel before 5.1.13, there is a memory     leak in drivers/scsi/libsas/sas_expander.c when SAS     expander discovery fails. This will cause a BUG and     denial of service. (CVE-2019-15807)

  - An issue was discovered in the Linux kernel before     5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which     will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in the Linux kernel before     5.0.4. The 9p filesystem did not protect i_size_write()     properly, which causes an i_size_read() infinite loop     and denial of service on SMP systems. (CVE-2019-16413)

  - An issue was discovered in write_tpt_entry in     drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel     through 5.3.2. The cxgb4 driver is directly calling     dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of     Service, exploitable if this driver is used on an     architecture for which this stack/DMA interaction has     security relevance. (CVE-2019-17075)

  - The SCTP socket buffer used by a userspace application     is not accounted by the cgroups subsystem. An attacker     can use this flaw to cause a denial of service attack.
    Kernel 3.10.x and 4.18.x branches are believed to be     vulnerable. (CVE-2019-3874)

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

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0756-1 advisory.

  - An issue was discovered in fs/gfs2/rgrp.c in the Linux kernel before 4.8. A use-after-free is caused by     the functions gfs2_clear_rgrpd and read_rindex_entry. (CVE-2016-10905)

  - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:
    Upstream kernel (CVE-2021-0920)

  - Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may     allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0001)

  - Non-transparent sharing of branch predictor within a context in some Intel(R) Processors may allow an     authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)

  - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the     kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups     v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
    (CVE-2022-0492)

  - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way     user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw     to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)

  - An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the     O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a     regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file     descriptor. (CVE-2022-24448)

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

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities:

  - The bnep_sock_ioctl function in     net/bluetooth/bnep/sock.c in the Linux kernel before     2.6.39 does not ensure that a certain device field ends     with a '\0' character, which allows local users to     obtain potentially sensitive information from kernel     stack memory, or cause a denial of service (BUG and     system crash), via a BNEPCONNADD command.
    (CVE-2011-1079)

  - An issue was discovered in fs/gfs2/rgrp.c in the Linux     kernel before 4.8. A use-after-free is caused by the     functions gfs2_clear_rgrpd and read_rindex_entry.
    (CVE-2016-10905)

  - An issue was discovered in     drivers/scsi/aacraid/commctrl.c in the Linux kernel     before 4.13. There is potential exposure of kernel stack     memory because aac_get_hba_info does not initialize the     hbainfo structure. (CVE-2017-18550)

  - An issue was discovered in the Linux kernel before     4.14.11. A double free may be caused by the function     allocate_trace_buffer in the file kernel/trace/trace.c.
    (CVE-2017-18595)

  - Improper invalidation for page table updates by a     virtual guest operating system for multiple Intel(R)     Processors may allow an authenticated user to     potentially enable denial of service of the host system     via local access. (CVE-2018-12207)

  - An issue was discovered in the Linux kernel before 4.20.
    There is a race condition in smp_task_timedout() and     smp_task_done() in drivers/scsi/libsas/sas_expander.c,     leading to a use-after-free. (CVE-2018-20836)

  - An issue was discovered in the Linux kernel before     4.18.7. In create_qp_common in     drivers/infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp     was never initialized, resulting in a leak of stack     memory to userspace. (CVE-2018-20855)

  - An issue was discovered in fs/xfs/xfs_super.c in the     Linux kernel before 4.18. A use after free exists,     related to xfs_fs_fill_super failure. (CVE-2018-20976)

  - In the tun subsystem in the Linux kernel before 4.13.14,     dev_get_valid_name is not called before     register_netdevice. This allows local users to cause a     denial of service (NULL pointer dereference and panic)     via an ioctl(TUNSETIFF) call with a dev name containing     a / character. This is similar to CVE-2013-4343.
    (CVE-2018-7191)

  - Insufficient access control in subsystem for Intel (R)     processor graphics in 6th, 7th, 8th and 9th Generation     Intel(R) Core(TM) Processor Families; Intel(R)     Pentium(R) Processor J, N, Silver and Gold Series;

    (CVE-2019-0155)

  - TSX Asynchronous Abort condition on some CPUs utilizing     speculative execution may allow an authenticated user to     potentially enable information disclosure via a side     channel with local access. (CVE-2019-11135)

  - The Linux kernel before 5.1-rc5 allows page->_refcount     reference count overflow, with resultant use-after-free     issues, if about 140 GiB of RAM exists. This is related     to fs/fuse/dev.c, fs/pipe.c, fs/splice.c,     include/linux/mm.h, include/linux/pipe_fs_i.h,     kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can     occur with FUSE requests. (CVE-2019-11487)

  - The do_hidp_sock_ioctl function in     net/bluetooth/hidp/sock.c in the Linux kernel before     5.0.15 allows a local user to obtain potentially     sensitive information from kernel stack memory via a     HIDPCONNADD command, because a name field may not end     with a '\0' character. (CVE-2019-11884)

  - ** DISPUTED ** An issue was discovered in     drm_load_edid_firmware in     drivers/gpu/drm/drm_edid_load.c in the Linux kernel     through 5.1.5. There is an unchecked kstrdup of fwstr,     which might allow an attacker to cause a denial of     service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a     vulnerability because kstrdup() returning NULL is     handled sufficiently and there is no chance for a NULL     pointer dereference. (CVE-2019-12382)

  - An issue was discovered in the Linux kernel before     5.2.3. There is a use-after-free caused by a malicious     USB device in the drivers/media/usb/dvb-usb/dvb-usb-     init.c driver. (CVE-2019-15213)

  - An issue was discovered in xfs_setattr_nonsize in     fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS     partially wedges when a chgrp fails on account of being     out of disk quota. xfs_setattr_nonsize is failing to     unlock the ILOCK after the xfs_qm_vop_chown_reserve call     fails. This is primarily a local DoS attack vector, but     it might result as well in remote DoS if the XFS     filesystem is exported for instance via NFS.
    (CVE-2019-15538)

  - In the Linux kernel before 5.1.13, there is a memory     leak in drivers/scsi/libsas/sas_expander.c when SAS     expander discovery fails. This will cause a BUG and     denial of service. (CVE-2019-15807)

  - An issue was discovered in the Linux kernel before     5.0.1. There is a memory leak in     register_queue_kobjects() in net/core/net-sysfs.c, which     will cause denial of service. (CVE-2019-15916)

  - An issue was discovered in the Linux kernel before     5.0.4. The 9p filesystem did not protect i_size_write()     properly, which causes an i_size_read() infinite loop     and denial of service on SMP systems. (CVE-2019-16413)

  - An issue was discovered in write_tpt_entry in     drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel     through 5.3.2. The cxgb4 driver is directly calling     dma_map_single (a DMA function) from a stack variable.
    This could allow an attacker to trigger a Denial of     Service, exploitable if this driver is used on an     architecture for which this stack/DMA interaction has     security relevance. (CVE-2019-17075)

  - The SCTP socket buffer used by a userspace application     is not accounted by the cgroups subsystem. An attacker     can use this flaw to cause a denial of service attack.
    Kernel 3.10.x and 4.18.x branches are believed to be     vulnerable. (CVE-2019-3874)
