  - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)

  - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a     do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in     a different security domain. Exploitation limitations include the amount of elapsed time before an integer     overflow occurs, and the lack of scenarios where signals to a parent process present a substantial     operational threat. (CVE-2020-12826)

  - A flaw was found in the Linux kernel's futex implementation. This flaw allows a local attacker to corrupt     system memory or escalate their privileges when creating a futex on a filesystem that is about to be     unmounted. The highest threat from this vulnerability is to confidentiality, integrity, as well as system     availability. (CVE-2020-14381)

  - A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length     biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a     denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block     device, resulting in a denial of service. The highest threat from this vulnerability is to system     availability. (CVE-2020-25641)

The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4226-1 advisory.

  - Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory     entry lists. (CVE-2019-10220)

  - A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before     4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection     negotiation during the handling of the remote devices country settings. This could allow the remote device     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895)

  - A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in     Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly     execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.
    (CVE-2019-14896)

  - A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip     driver. An attacker is able to cause a denial of service (system crash) or, possibly execute arbitrary     code, when a STA works in IBSS mode (allows connecting stations together without the use of an AP) and     connects to another STA. (CVE-2019-14897)

  - A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell     WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a     denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the     availability of the system. If code execution occurs, the code will run with the permissions of root. This     will affect both confidentiality and integrity of files on the system. (CVE-2019-14901)

  - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,     leading to a NULL pointer dereference. (CVE-2019-16231)

  - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,     leading to a NULL pointer dereference. (CVE-2019-16233)

  - 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)

  - In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a     long SSID IE, leading to a Buffer Overflow. (CVE-2019-17133)

  - The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is     not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to     arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. (CVE-2019-18660)

  - A memory leak in the dwc3_pci_probe() function in drivers/usb/dwc3/dwc3-pci.c in the Linux kernel through     5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering     platform_device_add_properties() failures, aka CID-9bbfceea12a8. (CVE-2019-18813)

(CVE-2019-19045)

  - A memory leak in the crypto_reportstat() function in drivers/virt/vboxguest/vboxguest_utils.c in the Linux     kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering     copy_form_user() failures, aka CID-e0b0cb938864. (CVE-2019-19048)

  - A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel before     5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb()     failures, aka CID-fb5be6a7b486. (CVE-2019-19052)

  - A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering     nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of this because     it occurs on a code path where a successful allocation has already occurred (CVE-2019-19055)

  - A memory leak in the adis_update_scan_mode() function in drivers/iio/imu/adis_buffer.c in the Linux kernel     before 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-ab612b1daf41.
    (CVE-2019-19060)

  - A memory leak in the sdma_init() function in drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel before     5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering rhashtable_init()     failures, aka CID-34b3be18a04e. NOTE: This has been disputed as not a vulnerability because     rhashtable_init() can only fail if it is passed invalid values in the second parameter's struct, but when     invoked from sdma_init() that is a pointer to a static const struct, so an attacker could only trigger     failure if they could corrupt kernel memory (in which case a small memory leak is not a significant     problem). (CVE-2019-19065)

  - Four memory leaks in the acp_hw_init() function in drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c in the Linux     kernel before 5.3.8 allow attackers to cause a denial of service (memory consumption) by triggering     mfd_add_hotplug_devices() or pm_genpd_add_device() failures, aka CID-57be09c6e874. NOTE: third parties     dispute the relevance of this because the attacker must already have privileges for module loading     (CVE-2019-19067)

  - A memory leak in the predicate_parse() function in kernel/trace/trace_events_filter.c in the Linux kernel     through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-96c5c6e6a5b6.

(CVE-2019-19532)

  - In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device     in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29. (CVE-2019-19534)

  - kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with     Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by     generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words,     although this slice expiration would typically be seen with benign workloads, it is possible that an     attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a     low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray     requests. An attack does not affect the stability of the kernel; it only causes mismanagement of     application execution.) (CVE-2019-19922)

  - In binder_transaction of binder.c, there is a possible out of bounds write due to a missing bounds check.
    This could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:

    (CVE-2020-10732)

  - In the Linux kernel 5.0.21, mounting a crafted ext4 filesystem image, performing some operations, and     unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list     in fs/ext4/super.c. (CVE-2019-19447)

  - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it     incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly     only validate the first netlink message in the skb and allow or deny the rest of the messages within the     skb with the granted permission without further processing. (CVE-2020-10751)

  - Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the     Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption), aka     CID-3f9361695113. (CVE-2019-19063)

  - 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)

  - ** DISPUTED ** A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c     in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by     triggering ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of     this because an attacker cannot realistically control this failure at probe time. (CVE-2019-19046)

  - In the Android kernel in the video driver there is a use after free due to a race condition. This could     lead to local escalation of privilege with no additional execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9458)

  - An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux     kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause     a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)

  - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c     has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing,     aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability     because the issue is a bug in parsing mount options which can only be specified by a privileged user, so     triggering the bug does not grant any powers not already held.. (CVE-2020-11565)

  - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a     do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in     a different security domain. Exploitation limitations include the amount of elapsed time before an integer     overflow occurs, and the lack of scenarios where signals to a parent process present a substantial     operational threat. (CVE-2020-12826)

  - A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length     biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a     denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block     device, resulting in a denial of service. The highest threat from this vulnerability is to system     availability. (CVE-2020-25641)

  - In audit_free_lsm_field of auditfilter.c, there is a possible bad kfree due to a logic error in     audit_data_to_entry.

User interaction is not needed for exploitation.Product: AndroidVersions: Android     kernelAndroid ID: A-150693166References: Upstream kernel (CVE-2020-0444)

  - A flaw was found in the Linux kernel's futex implementation. This flaw allows a local attacker to corrupt     system memory or escalate their privileges when creating a futex on a filesystem that is about to be     unmounted. The highest threat from this vulnerability is to confidentiality, integrity, as well as system     availability. (CVE-2020-14381)

  - In the Android kernel in the video driver there is a kernel pointer leak due to a WARN_ON statement. This     could lead to local information disclosure with System execution privileges needed. User interaction is     not needed for exploitation. (CVE-2019-9455)

  - A memory leak in the rtl8xxxu_submit_int_urb() function in     drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c in the Linux kernel through 5.3.11 allows attackers     to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka     CID-a2cdd07488e6. (CVE-2019-19068)

  - A memory leak in the predicate_parse() function in kernel/trace/trace_events_filter.c in the Linux kernel     through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-96c5c6e6a5b6.
    (CVE-2019-19072)

  - A memory disclosure flaw was found in the Linux kernel's versions before 4.18.0-193.el8 in the sysctl     subsystem when reading the /proc/sys/kernel/rh_features file. This flaw allows a local user to read     uninitialized values from the kernel memory. The highest threat from this vulnerability is to     confidentiality. (CVE-2020-10774)

  - An issue was discovered in the Linux kernel before 5.2.3. An out of bounds access exists in the function     hclge_tm_schd_mode_vnet_base_cfg in the file drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c.
    (CVE-2019-15925)

  - In the Linux kernel before 5.2, a setxattr operation, after a mount of a crafted ext4 image, can cause a     slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when     a large old_size value is used in a memset call, aka CID-345c0dbf3a30. (CVE-2019-19319)

  - In the Linux kernel before 5.1.6, there is a use-after-free in serial_ir_init_module() in     drivers/media/rc/serial_ir.c. (CVE-2019-19543)

  - fpregs_state_valid in arch/x86/include/asm/fpu/internal.h in the Linux kernel before 5.4.2, when GCC 9 is     used, allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have     unspecified other impact because of incorrect fpu_fpregs_owner_ctx caching, as demonstrated by mishandling     of signal-based non-cooperative preemption in Go 1.14 prereleases on amd64, aka CID-59c4bd853abc.
    (CVE-2019-19602)

  - ** DISPUTED ** In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove     function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously     created with a call to another debugfs function such as debugfs_create_file). NOTE: Linux kernel     developers dispute this issue as not being an issue with debugfs, instead this is an issue with misuse of     debugfs within blktrace. (CVE-2019-19770)

  - In cdev_get of char_dev.c, there is a possible use-after-free 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-10Android ID: A-153467744 (CVE-2020-0305)

  - A stack information leak flaw was found in s390/s390x in the Linux kernel's memory manager functionality,     where it incorrectly writes to the /proc/sys/vm/cmm_timeout file. This flaw allows a local user to see the     kernel data. (CVE-2020-10773)
