In the Linux kernel, the following vulnerability has been resolved: KVM: Don't null dereference ops->destroy A KVM device cleanup happens in either of two callbacks: 1) destroy() which is called when the VM is being destroyed; 2) release() which is called when a device fd is closed. Most KVM devices use 1) but Book3s's interrupt controller KVM devices (XICS, XIVE, XIVE-native) use 2) as they need to close and reopen during the machine execution. The error handling in kvm_ioctl_create_device() assumes destroy() is always defined which leads to NULL dereference as discovered by Syzkaller. This adds a checks for destroy!=NULL and adds a missing release(). This is not changing kvm_destroy_devices() as devices with defined release() should have been removed from the KVM devices list by then.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-988689 advisory.

The version of kernel installed on the remote host is prior to 5.10.135-122.509. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2025-086 advisory.

    An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

    A bug in the IMA subsystem was discovered which would incorrectly allow kexec to be used when kernel     lockdown was enabled (CVE-2022-21505)

    A flaw was found in hw. Aliases in the branch predictor may cause some AMD processors to predict the wrong     branch type, potentially leading to information disclosure. (CVE-2022-23825)

    Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow     an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)

    A flaw was found in hw. The unprotected alternative channel of return branch target prediction in some     Intel(R) Processors may allow an authorized user to enable information disclosure via local access.

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.

  - KVM: Don't null dereference ops->destroy A KVM device cleanup happens in either of two callbacks: 1)     destroy() which is called when the VM is being destroyed; 2) release() which is called when a device fd is     closed. Most KVM devices use 1) but Book3s's interrupt controller KVM devices (XICS, XIVE, XIVE-native)     use 2) as they need to close and reopen during the machine execution. The error handling in     kvm_ioctl_create_device() assumes destroy() is always defined which leads to NULL dereference as     discovered by Syzkaller. This adds a checks for destroy!=NULL and adds a missing release(). This is not     changing kvm_destroy_devices() as devices with defined release() should have been removed from the KVM     devices list by then. (CVE-2022-49568)

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

The version of kernel installed on the remote host is prior to 5.4.214-120.368. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-036 advisory.

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

    i2c: Fix a potential use after free

    Free the adap structure only after we are done using it.This patch just moves the put_device() down a bit     to avoid theuse after free.

    [wsa: added comment to the code, added Fixes tag] (CVE-2019-25162)

    A vulnerability was found in the Linux kernel's EBPF verifier when handling internal data structures.
    Internal memory locations could be returned to userspace.  A local attacker with the permissions to insert     eBPF code to the kernel can use this to leak internal kernel memory details defeating some of the exploit     mitigations in place for the kernel. (CVE-2021-4159)

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

    thermal: Fix NULL pointer dereferences in of_thermal_ functions (CVE-2021-47202)

    A use-after-free flaw was found in the Linux kernel's Atheros wireless adapter driver in the way a user     forces the ath9k_htc_wait_for_target function to fail with some input messages. This flaw allows a local     user to crash or potentially escalate their privileges on the system. (CVE-2022-1679)

    In v4l2_m2m_querybuf of v4l2-mem2mem.c, there is a possible out of bounds write due to improper input     validation. 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-223375145References: Upstream kernel (CVE-2022-20369)

    A flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it     possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This     flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel     oops condition that results in a denial of service. (CVE-2022-2153)

    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 use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the     Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege     escalation problem. (CVE-2022-2588)

    Non-transparent sharing of return predictor targets between contexts in some Intel(R) Processors may allow     an authorized user to potentially enable information disclosure via local access. (CVE-2022-26373)

    An issue was found in the Linux kernel in nf_conntrack_irc where the message handling can be confused and     incorrectly matches the message. A firewall may be able to be bypassed when users are using unencrypted     IRC with nf_conntrack_irc configured. (CVE-2022-2663)

    A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem)     when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to     potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read     and copying it into a socket. (CVE-2022-3028)

    A use-after-free flaw was found in io_uring in the Linux kernel. This flaw allows a local user to trigger     the issue if a signalfd or binder fd is polled with the io_uring poll due to a lack of io_uring POLLFREE     handling. (CVE-2022-3176)

    A vulnerability was found in Linux Kernel. It has been classified as critical. This affects the function     devlink_param_set/devlink_param_get of the file net/core/devlink.c of the component IPsec. The     manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier     VDB-211929 was assigned to this vulnerability. (CVE-2022-3625)

    An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

    A race condition in the Linux kernel's EFI capsule loader driver was found in the way it handled write and     flush operations on the device node of the EFI capsule. A local user could potentially use this flaw to     crash the system. (CVE-2022-40307)

    mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale TLB because an rmap lock is     not held during a PUD move. (CVE-2022-41222)

    -- the list head is all zeroes, this results in a NULL pointer dereference. (CVE-2023-1095)

    The upstream advisory describes this issue as follows:

    This vulnerability allows local attackers to disclose sensitive information on affected installations of     the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target     system in order to exploit this vulnerability.

    The specific flaw exists within the processing of seg6 attributes. The issue results from the lack of     proper validation of user-supplied data, which can result in a read past the end of an allocated buffer.
    An attacker can leverage this in conjunction with other vulnerabilties to escalate privileges and execute     arbitrary code in the context of the kernel. (CVE-2023-2860)

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 5.15.59-33.133. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2022-007 advisory.

    An out-of-bounds read flaw was found in the Linux kernel's TeleTYpe subsystem. The issue occurs in how a     user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage     of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read     unauthorized random data from memory. (CVE-2022-1462)

    A bug in the IMA subsystem was discovered which would incorrectly allow kexec to be used when kernel     lockdown was enabled (CVE-2022-21505)

    An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in     net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice. (CVE-2022-36879)

    A memory corruption flaw was found in the Linux kernel's Netfilter subsystem in the way a local user uses     the libnetfilter_queue when analyzing a corrupted network packet. This flaw allows a local user to crash     the system or a remote user to crash the system when the libnetfilter_queue is used by a local user.
    (CVE-2022-36946)
