The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-011122 advisory.

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

                                  -> Trigger warning

    In the above scenario, 'dquot->dq_flags' has no DQ_ACTIVE_B is normal when     dqgrab().
    To solve above issue just replace the dqgrab() use in invalidate_dquots() with     atomic_inc(&dquot->dq_count).

The version of kernel installed on the remote host is prior to 5.4.257-170.359. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2023-053 advisory.

    A flaw was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem). This issue     may allow a malicious user with CAP_NET_ADMIN privileges to directly dereference a NULL pointer in     xfrm_update_ae_params(), leading to a possible kernel crash and denial of service. (CVE-2023-3772)

    nftables out-of-bounds read in nf_osf_match_one() (CVE-2023-39189)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the     fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds     read by setting the size fields with a value beyond the array boundaries, leading to a crash or     information disclosure. (CVE-2023-39192)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the     flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds     read, leading to a crash or information disclosure. (CVE-2023-39193)

    A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing     of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local     privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an     information disclosure. (CVE-2023-39194)

    The upstream commit describes this issue as follows:

    The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can lead to the use of wrong     `CIDR_POS(c)` for calculating array offsets, which can lead to integer underflow. As a result, it leads to     slab out-of-bound access. (CVE-2023-42753)

    A flaw was found in rsvp_change(). The root cause is an slab-out-of-bound access, but since the offset to     the original pointer is an `unsign int` fully controlled by users, the behavior is usually a wild pointer     access. (CVE-2023-42755)

    An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel     before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)

    A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local     privilege escalation.

    The unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without     locking the queue. Thus there is a race where unix_stream_sendpage() could access an skb locklessly that     is being released by garbage collection, resulting in use-after-free.

    We recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c. (CVE-2023-4622)

    A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control)     component can be exploited to achieve local privilege escalation.

    If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing     curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in     update_vf(). This leaves a dangling pointer that can cause a use-after-free.

    We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f. (CVE-2023-4623)

    A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to     achieve local privilege escalation.

    When the plug qdisc is used as a class of the qfq qdisc, sending network packets triggers use-after-free     in qfq_dequeue() due to the incorrect .peek handler of sch_plug and lack of error checking in     agg_dequeue().

    We recommend upgrading past commit 8fc134fee27f2263988ae38920bc03da416b03d8. (CVE-2023-4921)

    In the Linux kernel before 6.4.12, amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c has     a fence use-after-free. (CVE-2023-51042)

(CVE-2023-6176)

The CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS-STREAM8:CLSA-2026:1789141176 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Propagate error from     htab_lock_bucket() to userspace In __htab_map_lookup_and_delete_batch() if htab_lock_bucket() returns
    -EBUSY, it will go to next bucket. Going to next bucket may not only skip the elements in current bucket     silently, but also incur out-of-bound memory access or expose kernel memory to userspace if current     bucket_cnt is greater than bucket_size or zero. Fixing it by stopping batch operation and returning -EBUSY     when htab_lock_bucket() fails, and the application can retry or skip the busy batch as needed.
    (CVE-2022-50490)

  - In the Linux kernel, the following vulnerability has been resolved: scsi: hpsa: Fix possible memory leak     in hpsa_init_one() The hpda_alloc_ctlr_info() allocates h and its field reply_map. However, in     hpsa_init_one(), if alloc_percpu() failed, the hpsa_init_one() jumps to clean1 directly, which frees h and     leaks the h->reply_map. Fix by calling hpda_free_ctlr_info() to release h->replay_map and h instead free h     directly. (CVE-2022-50646)

  - The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176. We recommend upgrading past commit     a664ec9158eeddd75121d39c9a0758016097fa96 (CVE-2023-0045)

  - A flaw was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem). This issue     may allow a malicious user with CAP_NET_ADMIN privileges to cause a 4 byte out-of-bounds read of     XFRMA_MTIMER_THRESH when parsing netlink attributes, leading to potential leakage of sensitive heap data     to userspace. (CVE-2023-3773)

  - In the Linux kernel, the following vulnerability has been resolved: fbdev: Fix invalid page access after     closing deferred I/O devices When a fbdev with deferred I/O is once opened and closed, the dirty pages     still remain queued in the pageref list, and eventually later those may be processed in the delayed work.
    This may lead to a corruption of pages, hitting an Oops. This patch makes sure to cancel the delayed work     and clean up the pageref list at closing the device for addressing the bug. A part of the cleanup code is     factored out as a new helper function that is called from the common fb_release(). (CVE-2023-52731)
