The version of kernel installed on the remote host is prior to 5.4.247-161.349. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2023-047 advisory.

    A flaw was found in the x86 KVM subsystem in kvm_steal_time_set_preempted in arch/x86/kvm/x86.c in the     Linux kernel. Unprivileged guest users can compromise the guest kernel because TLB flush operations are     mishandled in certain KVM_VCPU_PREEMPTED situations. (CVE-2022-39189)

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

    btrfs: unset reloc control if transaction commit fails in prepare_to_relocate() (CVE-2022-50067)

    There is a potential deadlock in the eBPF subsystem in the Linux kernel.

    The default sysctl configuration kernel.unprivileged_bpf_disabled on Amazon Linux does not allow     unprivileged users to use eBPF. (CVE-2023-0160)

    A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

    A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation.

    The out-of-bounds write is caused by missing skb->cb  initialization in the ipvlan network driver. The     vulnerability is reachable if CONFIG_IPVLAN is enabled.

    We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

    A use after free vulnerability was found in prepare_to_relocate in fs/btrfs/relocation.c in btrfs in the     Linux Kernel. This possible flaw can be triggered by calling btrfs_ioctl_balance() before calling     btrfs_ioctl_defrag(). (CVE-2023-3111)

    A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the     Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading     to a kernel information leak. (CVE-2023-3141)

    An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

    An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. (CVE-2023-34256)

    A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal     kernel information. (CVE-2023-3567)

    An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation. (CVE-2023-35788)

Tenable has extracted the preceding description block directly from the tested product 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 Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013154 advisory.

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

    spmi: Add a check for remove callback when removing a SPMI driver

    When removing a SPMI driver, there can be a crash due to NULL pointer     dereference if it does not have a remove callback defined. This is     one such call trace observed when removing the QCOM SPMI PMIC driver:

     dump_backtrace.cfi_jt+0x0/0x8      dump_stack_lvl+0xd8/0x16c      panic+0x188/0x498
     __cfi_slowpath+0x0/0x214
     __cfi_slowpath+0x1dc/0x214      spmi_drv_remove+0x16c/0x1e0      device_release_driver_internal+0x468/0x79c      driver_detach+0x11c/0x1a0      bus_remove_driver+0xc4/0x124      driver_unregister+0x58/0x84      cleanup_module+0x1c/0xc24 [qcom_spmi_pmic]
     __do_sys_delete_module+0x3ec/0x53c
     __arm64_sys_delete_module+0x18/0x28      el0_svc_common+0xdc/0x294      el0_svc+0x38/0x9c      el0_sync_handler+0x8c/0xf0      el0_sync+0x1b4/0x1c0

    If a driver has all its resources allocated through devm_() APIs and     does not need any other explicit cleanup, it would not require a     remove callback to be defined. Hence, add a check for remove callback     presence before calling it when removing a SPMI driver.

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.

The version of kernel installed on the remote host is prior to 5.10.184-174.730. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-034 advisory.

    A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking     configuration (redirecting egress packets to ingress using TC action mirred) a local unprivileged user     could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a     retransmission, resulting in a denial of service condition. (CVE-2022-4269)

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

    btrfs: unset reloc control if transaction commit fails in prepare_to_relocate() (CVE-2022-50067)

    There is a potential deadlock in the eBPF subsystem in the Linux kernel.

    The default sysctl configuration kernel.unprivileged_bpf_disabled on Amazon Linux does not allow     unprivileged users to use eBPF. (CVE-2023-0160)

    A flaw was found in the Linux kernel's networking subsystem within the RPL protocol's handling. This issue     results from the improper handling of user-supplied data, which can lead to an assertion failure. This     flaw allows an unauthenticated, remote attacker to create a denial of service condition on the system.
    (CVE-2023-2156)

    A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation.

    The out-of-bounds write is caused by missing skb->cb  initialization in the ipvlan network driver. The     vulnerability is reachable if CONFIG_IPVLAN is enabled.

    We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

    A use after free vulnerability was found in prepare_to_relocate in fs/btrfs/relocation.c in btrfs in the     Linux Kernel. This possible flaw can be triggered by calling btrfs_ioctl_balance() before calling     btrfs_ioctl_defrag(). (CVE-2023-3111)

    A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the     Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading     to a kernel information leak. (CVE-2023-3141)

    A flaw in the Linux Kernel found in the GFS2 file system. On corrupted gfs2 file systems the evict code     can try to reference the journal descriptor structure, jdesc, after it has been freed and set to NULL. It     can lead to null pointer dereference when gfs2_trans_begin being called and then fail     ingfs2_evict_inode(). (CVE-2023-3212)

    An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

    An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. (CVE-2023-34256)

    A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal     kernel information. (CVE-2023-3567)

    An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation. (CVE-2023-35788)

    A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This     flaw allows a local user to cause an information leak problem while freeing the old quota file names     before a potential failure, leading to a use-after-free. (CVE-2024-0775)

Tenable has extracted the preceding description block directly from the tested product 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 5.15.117-72.142. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-021 advisory.

    In the Linux kernel through 6.2.7, fs/ntfs3/inode.c has an invalid kfree because it does not validate MFT     flags before replaying logs. (CVE-2022-48425)

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

    binder: fix UAF of alloc->vma in race with munmap() (CVE-2022-50240)

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

    There is a potential deadlock in the eBPF subsystem in the Linux kernel.

    The default sysctl configuration kernel.unprivileged_bpf_disabled on Amazon Linux does not allow     unprivileged users to use eBPF. (CVE-2023-0160)

    A flaw was found in the Linux kernel's networking subsystem within the RPL protocol's handling. This issue     results from the improper handling of user-supplied data, which can lead to an assertion failure. This     flaw allows an unauthenticated, remote attacker to create a denial of service condition on the system.
    (CVE-2023-2156)

    A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation.

    The out-of-bounds write is caused by missing skb->cb  initialization in the ipvlan network driver. The     vulnerability is reachable if CONFIG_IPVLAN is enabled.

    We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

    A flaw in the Linux Kernel found in the GFS2 file system. On corrupted gfs2 file systems the evict code     can try to reference the journal descriptor structure, jdesc, after it has been freed and set to NULL. It     can lead to null pointer dereference when gfs2_trans_begin being called and then fail     ingfs2_evict_inode(). (CVE-2023-3212)

    An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

    An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. (CVE-2023-34256)

    A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal     kernel information. (CVE-2023-3567)

    An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7.
    It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets.
    This may result in denial of service or privilege escalation. (CVE-2023-35788)

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

    ext4: fix deadlock when converting an inline directory in nojournal mode (CVE-2023-54311)

    A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This     flaw allows a local user to cause an information leak problem while freeing the old quota file names     before a potential failure, leading to a use-after-free. (CVE-2024-0775)

Tenable has extracted the preceding description block directly from the tested product 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 4.14.318-240.529. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2100 advisory.

    It was discovered that a nft object or expression could reference a nft set on a different nft table,     leading to a use-after-free once that table was deleted. (CVE-2022-2586)

    A heap buffer overflow flaw was found in the Linux kernel's Netfilter subsystem in the way a user provides     incorrect input of the NFT_DATA_VERDICT type. This flaw allows a local user to crash or potentially     escalate their privileges on the system. (CVE-2022-34918)

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

    btrfs: unset reloc control if transaction commit fails in prepare_to_relocate() (CVE-2022-50067)

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

    netfilter: nf_tables: do not allow SET_ID to refer to another table (CVE-2022-50213)

    A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

    do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

    A heap out-of-bounds write vulnerability in the Linux Kernel ipvlan network driver can be exploited to     achieve local privilege escalation.

    The out-of-bounds write is caused by missing skb->cb  initialization in the ipvlan network driver. The     vulnerability is reachable if CONFIG_IPVLAN is enabled.

    We recommend upgrading past commit 90cbed5247439a966b645b34eb0a2e037836ea8e. (CVE-2023-3090)

    A use after free vulnerability was found in prepare_to_relocate in fs/btrfs/relocation.c in btrfs in the     Linux Kernel. This possible flaw can be triggered by calling btrfs_ioctl_balance() before calling     btrfs_ioctl_defrag(). (CVE-2023-3111)

    A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the     Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading     to a kernel information leak. (CVE-2023-3141)

    An issue was discovered in the Linux kernel before 6.3.3. There is an out-of-bounds read in crc16 in     lib/crc16.c when called from fs/ext4/super.c because ext4_group_desc_csum does not properly check an     offset. (CVE-2023-34256)

    serial: 8250: Reinit port->pm on port specific driver unbind (CVE-2023-53176)
