Tenable has extracted the preceding description block directly from the EulerOS kernel security advisory.

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

The version of kernel installed on the remote host is prior to 4.14.262-135.489. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2022-1563 advisory.

    2025-01-30: CVE-2021-47483 was added to this advisory.

    2025-01-30: CVE-2021-47506 was added to this advisory.

    A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux     kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an     off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this     vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source     port randomization are indirectly affected as well. (CVE-2021-20322)

    A denial of service flaw for virtual machine guests in the Linux kernel's Xen hypervisor subsystem was     found in the way users call some interrupts with high frequency from one of the guests.A local user could     use this flaw to starve the resources resulting in a denial of service. (CVE-2021-28711)

(CVE-2021-28713)

    Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: The timeout could even never trigger if the guest manages to have only one free     slot in its RX queue ring page and the next package would require more than one free slot, which may be     the case when using GSO, XDP, or software hashing. (CVE-2021-28714)

    Incoming data packets for a guest in the Linux kernel's netback driver are buffered until the guest is     ready to process them. There are some measures taken for avoiding to pile up too much data, but those can     be bypassed by the guest: There is a timeout how long the client side of an interface can stop consuming     new packets before it is assumed to have stalled, but this timeout is rather long (60 seconds by default).
    Using a UDP connection on a fast interface can easily accumulate gigabytes of data in that time.
    (CVE-2021-28715)

    A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP     association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and     the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

    A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some     regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the     memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

    A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size     increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS     filesystem otherwise not accessible to them. (CVE-2021-4155)

    In the Linux kernel, the following vulnerability has been resolved:

    regmap: Fix possible double-free in regcache_rbtree_exit() (CVE-2021-47483)

    In the Linux kernel, the following vulnerability has been resolved:

    nfsd: fix use-after-free due to delegation race (CVE-2021-47506)

    The cgroup release_agent is called with call_usermodehelper. The function call_usermodehelper starts the     release_agent with a full set of capabilities. Therefore require capabilities when setting the     release_agent. (CVE-2022-0492)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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

The CentOS Linux 8.5 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.5:CLSA-2026:1780076591 advisory.

  - 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, the following vulnerability has been resolved: media: ngene: Fix out-of-bounds bug in     ngene_command_config_free_buf() Fix an 11-year old bug in ngene_command_config_free_buf() while addressing     the following warnings caught with -Warray-bounds: arch/alpha/include/asm/string.h:22:16: warning:
    '__builtin_memcpy' offset [12, 16] from the object at 'com' is out of the bounds of referenced subobject     'config' with type 'unsigned char' at offset 10 [-Warray-bounds] arch/x86/include/asm/string_32.h:182:25:
    warning: '__builtin_memcpy' offset [12, 16] from the object at 'com' is out of the bounds of referenced     subobject 'config' with type 'unsigned char' at offset 10 [-Warray-bounds] The problem is that the     original code is trying to copy 6 bytes of data into a one-byte size member _config_ of the wrong structue     FW_CONFIGURE_BUFFERS, in a single call to memcpy(). This causes a legitimate compiler warning because     memcpy() overruns the length of &com.cmd.ConfigureBuffers.config. It seems that the right structure is     FW_CONFIGURE_FREE_BUFFERS, instead, because it contains 6 more members apart from the header _hdr_. Also,     the name of the function ngene_command_config_free_buf() suggests that the actual intention is to     ConfigureFreeBuffers, instead of ConfigureBuffers (which takes place in the function     ngene_command_config_buf(), above). Fix this by enclosing those 6 members of struct     FW_CONFIGURE_FREE_BUFFERS into new struct config, and use &com.cmd.ConfigureFreeBuffers.config as the     destination address, instead of &com.cmd.ConfigureBuffers.config, when calling memcpy(). This also helps     with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the     FORTIFY_SOURCE routines on memcpy(). (CVE-2021-47288)

  - In the Linux kernel, the following vulnerability has been resolved: net/sched: act_skbmod: Skip non-     Ethernet packets Currently tcf_skbmod_act() assumes that packets use Ethernet as their L2 protocol, which     is not always the case. As an example, for CAN devices: $ ip link add dev vcan0 type vcan $ ip link set up     vcan0 $ tc qdisc add dev vcan0 root handle 1: htb $ tc filter add dev vcan0 parent 1: protocol ip prio 10     \ matchall action skbmod swap mac Doing the above silently corrupts all the packets. Do not perform skbmod     actions for non-Ethernet packets. (CVE-2021-47293)

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

  - In the Linux kernel, the following vulnerability has been resolved: netfilter: synproxy: Fix out of bounds     when parsing TCP options The TCP option parser in synproxy (synproxy_parse_options) could read one byte     out of bounds. When the length is 1, the execution flow gets into the loop, reads one byte of the opcode,     and if the opcode is neither TCPOPT_EOL nor TCPOPT_NOP, it reads one more byte, which exceeds the length     of 1. This fix is inspired by commit 9609dad263f8 (ipv4: tcp_input: fix stack out of bounds when parsing     TCP options.). v2 changes: Added an early return when length < 0 to avoid calling skb_header_pointer with     negative length. (CVE-2021-47245)

  - In the Linux kernel, the following vulnerability has been resolved: drm: Fix use-after-free read in     drm_getunique() There is a time-of-check-to-time-of-use error in drm_getunique() due to retrieving     file_priv->master prior to locking the device's master mutex. An example can be seen in the crash report     of the use-after-free error found by Syzbot:
    https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f803 In the report, the master     pointer was used after being freed. This is because another process had acquired the device's master mutex     in drm_setmaster_ioctl(), then overwrote fpriv->master in drm_new_set_master(). The old value of     fpriv->master was subsequently freed before the mutex was unlocked. To fix this, we lock the device's     master mutex before retrieving the pointer from from fpriv->master. This patch passes the Syzbot     reproducer test. (CVE-2021-47280)

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

The version of kernel installed on the remote host is prior to 5.4.162-86.275. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2025-093 advisory.

    A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could     happen if removing device (that is not common to remove video card physically without power-off, but same     happens if unbind the driver). (CVE-2020-27820)

    A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the     way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del()     together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A     privileged local user could use this flaw to crash the system or escalate their privileges on the system.
    (CVE-2021-3640)

    A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP     association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and     the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

    A race condition was found in the Linux kernel's ebpf verifier between bpf_map_update_elem and     bpf_map_freeze due to a missing lock in kernel/bpf/syscall.c. In this flaw, a local user with a special     privilege (cap_sys_admin or cap_bpf) can modify the frozen mapped address space. (CVE-2021-4001)

    A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some     regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the     memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

Tenable has extracted the preceding description block directly from the EulerOS kernel security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: regmap: Fix possible double-free in     regcache_rbtree_exit() In regcache_rbtree_insert_to_block(), when 'present' realloc failed, the 'blk'     which is supposed to assign to 'rbnode->block' will be freed, so 'rbnode->block' points a freed memory, in     the error handling path of regcache_rbtree_init(), 'rbnode->block' will be freed again in     regcache_rbtree_exit(), KASAN will report double-free as follows: BUG: KASAN: double-free or invalid-free     in kfree+0xce/0x390 Call Trace: slab_free_freelist_hook+0x10d/0x240 kfree+0xce/0x390     regcache_rbtree_exit+0x15d/0x1a0 regcache_rbtree_init+0x224/0x2c0 regcache_init+0x88d/0x1310
    __regmap_init+0x3151/0x4a80 __devm_regmap_init+0x7d/0x100 madera_spi_probe+0x10f/0x333 [madera_spi]     spi_probe+0x183/0x210 really_probe+0x285/0xc30 To fix this, moving up the assignment of rbnode->block to     immediately after the reallocation has succeeded so that the data structure stays valid even if the second     reallocation fails. (CVE-2021-47483)

Note that Nessus relies on the presence of the package as reported by the vendor.
