The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-000336 advisory.

    In the Linux kernel 4.19 through 5.6.7 on the s390 platform, code execution may occur because of a race     condition, as demonstrated by code in enable_sacf_uaccess in arch/s390/lib/uaccess.c that fails to protect     against a concurrent page table upgrade, aka CID-3f777e19d171. A crash could also occur.

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

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

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

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

  - A NULL pointer dereference flaw was found in the Linux     kernel's SELinux subsystem. This flaw occurs while     importing the Commercial IP Security Option (CIPSO)     protocol's category bitmap into the SELinux extensible     bitmap via the' ebitmap_netlbl_import' routine. While     processing the CIPSO restricted bitmap tag in the     'cipso_v4_parsetag_rbm' routine, it sets the security     attribute to indicate that the category bitmap is     present, even if it has not been allocated. This issue     leads to a NULL pointer dereference issue while     importing the same category bitmap into SELinux. This     flaw allows a remote network user to crash the system     kernel, resulting in a denial of     service.(CVE-2020-10711)

  - 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)

  - An issue was discovered in the Linux kernel before     5.4.17. drivers/spi/spi-dw.c allows attackers to cause     a panic via concurrent calls to dw_spi_irq and     dw_spi_transfer_one, aka     CID-19b61392c5a8.(CVE-2020-12769)

  - 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)

  - An issue was discovered in the Linux kernel through     5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c     has a deadlock if a coalescing operation     fails.(CVE-2020-12771)

  - 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 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 pivot_root race condition in fs amespace.c in the     Linux kernel 4.4.x before 4.4.221, 4.9.x before     4.9.221, 4.14.x before 4.14.178, 4.19.x before     4.19.119, and 5.x before 5.3 allows local users to     cause a denial of service (panic) by corrupting a     mountpoint reference counter.(CVE-2020-12114)

  - An issue was discovered in the Linux kernel before     5.6.5. There is a use-after-free in block/bfq-iosched.c     related to bfq_idle_slice_timer_body.(CVE-2020-12657)

  - usb_sg_cancel in drivers/usb/core/message.c in the     Linux kernel before 5.6.8 has a use-after-free because     a transfer occurs without a reference, aka     CID-056ad39ee925.(CVE-2020-12464)

  - An issue was found in Linux kernel before 5.5.4. The     mwifiex_cmd_append_vsie_tlv() function in drivers     et/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)

  - gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c     in the rpcsec_gss_krb5 implementation in the Linux     kernel through 5.6.10 lacks certain domain_release     calls, leading to a memory leak.(CVE-2020-12656)

  - An issue was discovered in the Linux kernel before     5.6.7. xdp_umem_reg in net/xdp/xdp_umem.c has an     out-of-bounds write (by a user with the CAP_NET_ADMIN     capability) because of a lack of headroom     validation.(CVE-2020-12659)

  - An array overflow was discovered in mt76_add_fragment     in drivers et/wireless/mediatek/mt76/dma.c in the Linux     kernel before 5.5.10, aka CID-b102f0c522cf. An     oversized packet with too many rx fragments can corrupt     memory of adjacent pages.(CVE-2020-12465)

  - An issue was found in Linux kernel before 5.5.4.
    mwifiex_ret_wmm_get_status() in drivers     et/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)

  - In the Linux kernel through 5.6.7 on the s390 platform,     code execution may occur because of a race condition,     as demonstrated by code in enable_sacf_uaccess in     arch/s390/lib/uaccess.c that fails to protect against a     concurrent page table upgrade, aka CID-3f777e19d171. A     crash could also occur.(CVE-2020-11884)

  - relay_open in kernel/relay.c in the Linux kernel     through 5.4.1 allows local users to cause a denial of     service (such as relay blockage) by triggering a NULL     alloc_percpu result.(CVE-2019-19462)

  - 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)

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

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

The remote NewStart CGSL host, running version MAIN 6.01, has kernel packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in the Linux kernel's NFS     implementation, all versions 3.x and all versions 4.x up     to 4.20. An attacker, who is able to mount an exported     NFS filesystem, is able to trigger a null pointer     dereference by using an invalid NFS sequence. This can     panic the machine and deny access to the NFS server. Any     outstanding disk writes to the NFS server will be lost.
    (CVE-2018-16871)

  - ieee802154_create in net/ieee802154/socket.c in the     AF_IEEE802154 network module in the Linux kernel through     5.3.2 does not enforce CAP_NET_RAW, which means that     unprivileged users can create a raw socket, aka     CID-e69dbd4619e7. (CVE-2019-17053)

  - base_sock_create in drivers/isdn/mISDN/socket.c in the     AF_ISDN network module in the Linux kernel through 5.3.2     does not enforce CAP_NET_RAW, which means that     unprivileged users can create a raw socket, aka     CID-b91ee4aa2a21. (CVE-2019-17055)

  - The flow_dissector feature in the Linux kernel 4.3     through 5.x before 5.3.10 has a device tracking     vulnerability, aka CID-55667441c84f. This occurs because     the auto flowlabel of a UDP IPv6 packet relies on a     32-bit hashrnd value as a secret, and because jhash     (instead of siphash) is used. The hashrnd value remains     the same starting from boot time, and can be inferred by     an attacker. This affects net/core/flow_dissector.c and     related code. (CVE-2019-18282)

  - An issue was discovered in net/ipv4/sysctl_net_ipv4.c in     the Linux kernel before 5.0.11. There is a     net/ipv4/tcp_input.c signed integer overflow in     tcp_ack_update_rtt() when userspace writes a very large     integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading     to a denial of service or possibly unspecified other     impact, aka CID-19fad20d15a6. (CVE-2019-18805)

  - A memory leak in the mlx5_fpga_conn_create_cq() function     in drivers/net/ethernet/mellanox/mlx5/core/fpga/conn.c     in the Linux kernel before 5.3.11 allows attackers to     cause a denial of service (memory consumption) by     triggering mlx5_vector2eqn() failures, aka     CID-c8c2a057fdc7. (CVE-2019-19045)

  - ** DISPUTED ** 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 bnxt_re_create_srq() function in     drivers/infiniband/hw/bnxt_re/ib_verbs.c in the Linux     kernel through 5.3.11 allows attackers to cause a denial     of service (memory consumption) by triggering copy to     udata failures, aka CID-4a9d46a9fe14. (CVE-2019-19077)

  - In the Linux kernel before 5.3.9, there are multiple     out-of-bounds write bugs that can be caused by a     malicious USB device in the Linux kernel HID drivers,     aka CID-d9d4b1e46d95. This affects drivers/hid/hid-     axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c,     drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,     drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c,     drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,     drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-     microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-     tmff.c, and drivers/hid/hid-zpff.c. (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)

  - In the Linux kernel 5.4.0-rc2, there is a use-after-free     (read) in the __blk_add_trace function in     kernel/trace/blktrace.c (which is used to fill out a     blk_io_trace structure and place it in a per-cpu sub-     buffer). (CVE-2019-19768)

  - A memory leak in the kernel_read_file function in     fs/exec.c in the Linux kernel through 4.20.11 allows     attackers to cause a denial of service (memory     consumption) by triggering vfs_read failures.
    (CVE-2019-8980)

  - A NULL pointer dereference flaw was found in the Linux     kernel's SELinux subsystem in versions before 5.7. This     flaw occurs while importing the Commercial IP Security     Option (CIPSO) protocol's category bitmap into the     SELinux extensible bitmap via the'     ebitmap_netlbl_import' routine. While processing the     CIPSO restricted bitmap tag in the     'cipso_v4_parsetag_rbm' routine, it sets the security     attribute to indicate that the category bitmap is     present, even if it has not been allocated. This issue     leads to a NULL pointer dereference issue while     importing the same category bitmap into SELinux. This     flaw allows a remote network user to crash the system     kernel, resulting in a denial of service.
    (CVE-2020-10711)

  - In the Linux kernel through 5.6.7 on the s390 platform,     code execution may occur because of a race condition, as     demonstrated by code in enable_sacf_uaccess in     arch/s390/lib/uaccess.c that fails to protect against a     concurrent page table upgrade, aka CID-3f777e19d171. A     crash could also occur. (CVE-2020-11884)

  - An issue was discovered in the Linux kernel before     5.6.5. There is a use-after-free in block/bfq-iosched.c     related to bfq_idle_slice_timer_body. (CVE-2020-12657)

  - A flaw was discovered in the way that the KVM hypervisor     handled instruction emulation for an L2 guest when     nested virtualisation is enabled. Under some     circumstances, an L2 guest may trick the L0 guest into     accessing sensitive L1 resources that should be     inaccessible to the L2 guest. (CVE-2020-2732)
