The version of kernel installed on the remote host is prior to 5.4.68-34.125. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-016 advisory.

    A flaw was found in the Linux kernel's implementation of BTRFS free space management, where the kernel     does not correctly manage the lifetime of internal data structures used. An attacker could use this flaw     to corrupt memory or escalate privileges. (CVE-2019-19448)

    A use-after-free flaw was found in the debugfs_remove function in the Linux kernel. The flaw could allow a     local attacker with special user (or root) privilege to crash the system at the time of file or directory     removal. This vulnerability can lead to a kernel information leak. The highest threat from this     vulnerability is to system availability. (CVE-2019-19770)

    A flaw was found in the Linux kernel, where it allows userspace processes, for example, a guest VM, to     directly access h/w devices via its VFIO driver modules. The VFIO modules allow users to enable or disable     access to the devices' MMIO memory address spaces. If a user attempts to access the read/write devices'     MMIO address space when it is disabled, some h/w devices issue an interrupt to the CPU to indicate a fatal     error condition, crashing the system. This flaw allows a guest user or process to crash the host system     resulting in a denial of service. (CVE-2020-12888)

    A memory out-of-bounds read flaw was found in the Linux kernel's ext3/ext4 file system, in the way it     accesses a directory with broken indexing. This flaw allows a local user to crash the system if the     directory exists. The highest threat from this vulnerability is to system availability. (CVE-2020-14314)

    A flaw was found in the Linux kernel. A failure of the file system metadata validator in XFS can cause an     inode with a valid, user-creatable extended attribute to be flagged as corrupt.  This can lead to the     filesystem being shutdown, or otherwise rendered inaccessible until it is remounted, leading to a denial     of service. The highest threat from this vulnerability is to system availability. (CVE-2020-14385)

    A flaw was found in the Linux kernel. When changing screen size, an out-of-bounds memory write can occur     leading to memory corruption or a denial of service. Due to the nature of the flaw, privilege escalation     cannot be fully ruled out. (CVE-2020-14390)

    A flaw was found in the NFSv4 implementation where when mounting a remote attacker controlled server it     could return specially crafted response allow for local memory corruption and possibly privilege     escalation. (CVE-2020-25212)

    A flaw was found in the capabilities check of the rados block device functionality in the Linux kernel.
    Incorrect capability checks could alllow a local user with root priviledges (but no capabilities) to add     or remove Rados Block Devices from the system. (CVE-2020-25284)

    A flaw was found in the Linux kernels sysctl handling code for hugepages management. When multiple root     level processes would write to modify the /proc/sys/vm/nr_hugepages file it could create a race on     internal variables leading to a system crash or memory corruption. (CVE-2020-25285)

    A flaw was found in the Linux kernel's implementation of biovecs. 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)

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

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

  - The Linux kernel through 5.7.11 allows remote attackers     to make observations that help to obtain sensitive     information about the internal state of the network     RNG, aka CID-f227e3ec3b5c. This is related to     drivers/char/random.c and     kernel/time/timer.c.(CVE-2020-16166)

  - A flaw was found in the Linux kernel's implementation     of the invert video code on VGA consoles when a local     attacker attempts to resize the console, calling an     ioctl VT_RESIZE, which causes an out-of-bounds write to     occur. This flaw allows a local user with access to the     VGA console to crash the system, potentially escalating     their privileges on the system. The highest threat from     this vulnerability is to data confidentiality and     integrity as well as system     availability.(CVE-2020-14331)

  - 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)

  - An issue was discovered in the Linux kernel through     5.7.1. drivers/tty/vt/keyboard.c has an integer     overflow if k_ascii is called several times in a row,     aka CID-b86dab054059. NOTE: Members in the community     argue that the integer overflow does not lead to a     security issue in this case.(CVE-2020-13974)

  - In the Linux kernel through 5.7.6, usbtest_disconnect     in drivers/usb/misc/usbtest.c has a memory leak, aka     CID-28ebeb8db770.(CVE-2020-15393)

  - The VFIO PCI driver in the Linux kernel through 5.6.13     mishandles attempts to access disabled memory     space.(CVE-2020-12888)

  - go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)

  - An issue was discovered in the Linux kernel before     5.0.6. In rx_queue_add_kobject() and     netdev_queue_add_kobject() in net/core/net-sysfs.c, a     reference count is mishandled, aka     CID-a3e23f719f5c.(CVE-2019-20811)

  - 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)

  - A flaw was found in the Linux kernel's implementation     of Userspace core dumps. This flaw allows an attacker     with a local account to crash a trivial program and     exfiltrate private kernel data.(CVE-2020-10732)

  - 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)

  - gadget_dev_desc_UDC_store in     drivers/usb/gadget/configfs.c in the Linux kernel     through 5.6.13 relies on kstrdup without considering     the possibility of an internal '\0' value, which allows     attackers to trigger an out-of-bounds read, aka     CID-15753588bcd4.(CVE-2020-13143)

  - 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)

  - The __mptctl_ioctl function in     drivers/message/fusion/mptctl.c in the Linux kernel     before 5.4.14 allows local users to hold an incorrect     lock during the ioctl operation and trigger a race     condition, i.e., a 'double fetch' vulnerability, aka     CID-28d76df18f0a. NOTE: the vendor states 'The security     impact of this bug is not as bad as it could have been     because these operations are all privileged and root     already has enormous destructive     power.'(CVE-2020-12652)

  - An issue was found in Linux kernel before 5.5.4. The     mwifiex_cmd_append_vsie_tlv() function in     drivers/net/wireless/marvell/mwifiex/scan.c allows     local users to gain privileges or cause a denial of     service because of an incorrect memcpy and buffer     overflow, aka CID-b70261a288ea.(CVE-2020-12653)

  - An issue was found in Linux kernel before 5.5.4.
    mwifiex_ret_wmm_get_status() in     drivers/net/wireless/marvell/mwifiex/wmm.c allows a     remote AP to trigger a heap-based buffer overflow     because of an incorrect memcpy, aka     CID-3a9b153c5591.(CVE-2020-12654)

  - An issue was discovered in xfs_agf_verify in     fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through     5.6.10. Attackers may trigger a sync of excessive     duration via an XFS v5 image with crafted metadata, aka     CID-d0c7feaf8767.(CVE-2020-12655)

  - A flaw was found in the Linux kernel's implementation     of GRO in versions before 5.2. This flaw allows an     attacker with local access to crash the     system.(CVE-2020-10720)

  - 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)

  - In the Linux kernel before 5.4.12,     drivers/input/input.c has out-of-bounds writes via a     crafted keycode table, as demonstrated by     input_set_keycode, aka     CID-cb222aed03d7.(CVE-2019-20636)

  - An issue was discovered in the stv06xx subsystem in the     Linux kernel before 5.6.1.
    drivers/media/usb/gspca/stv06xx/stv06xx.c and     drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c     mishandle invalid descriptors, as demonstrated by a     NULL pointer dereference, aka     CID-485b06aadb93.(CVE-2020-11609)

  - In the netlink driver, there is a possible out of     bounds write 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-65025077(CVE-2020-0066)

  - In the Linux kernel before 5.5.8, get_raw_socket in     drivers/vhost/net.c lacks validation of an sk_family     field, which might allow attackers to trigger kernel     stack corruption via crafted system     calls.(CVE-2020-10942)

  - An issue was discovered in slc_bump in     drivers/net/can/slcan.c in the Linux kernel through     5.6.2. It allows attackers to read uninitialized     can_frame data, potentially containing sensitive     information from kernel stack memory, if the     configuration lacks CONFIG_INIT_STACK_ALL, aka     CID-b9258a2cece4.(CVE-2020-11494)

  - 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)

  - An issue was discovered in the Linux kernel before     5.6.1. drivers/media/usb/gspca/ov519.c allows NULL     pointer dereferences in ov511_mode_init_regs and     ov518_mode_init_regs when there are zero endpoints, aka     CID-998912346c0d.(CVE-2020-11608)

  - The kernel in Red Hat Enterprise Linux 7 and MRG-2 does     not clear garbage data for SG_IO buffer, which may     leaking sensitive information to     userspace.(CVE-2014-8181)

  - 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)
