The CentOS Linux 8.5 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.5:CLSA-2026:1782146775 advisory.

  - Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory     entry lists. (CVE-2019-10220)

  - The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. (CVE-2019-7221)

  - Improper input validation in BlueZ may allow an unauthenticated user to potentially enable escalation of     privilege via adjacent access. (CVE-2020-12351)

  - Improper access control in BlueZ may allow an unauthenticated user to potentially enable information     disclosure via adjacent access. (CVE-2020-12352)

  - Improper buffer restrictions in BlueZ may allow an unauthenticated user to potentially enable denial of     service via adjacent access. This affects all Linux kernel versions that support BlueZ. (CVE-2020-24490)

The CentOS Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS-STREAM8:CLSA-2026:1782375682 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Don't redirect packets with     invalid pkt_len Syzbot found an issue [1]: fq_codel_drop() try to drop a flow whitout any skbs, that is,     the flow->head is null. The root cause, as the [2] says, is because that bpf_prog_test_run_skb() run a bpf     prog which redirects empty skbs. So we should determine whether the length of the packet modified by bpf     prog or others like bpf_prog_test is valid before forwarding it directly. (CVE-2022-49975)

  - In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: debug: Fix potential buffer     overflow by snprintf() snprintf() returns the would-be-filled size when the string overflows the given     buffer size, hence using this value may result in the buffer overflow (although it's unrealistic). This     patch replaces with a safer version, scnprintf() for papering over such a potential issue.
    (CVE-2022-50051)

  - In the Linux kernel, the following vulnerability has been resolved: x86/alternatives: Disable KASAN in     apply_alternatives() Fei has reported that KASAN triggers during apply_alternatives() on a 5-level paging     machine: BUG: KASAN: out-of-bounds in rcu_is_watching() Read of size 4 at addr ff110003ee6419a0 by task     swapper/0/0 ... __asan_load4() rcu_is_watching() trace_hardirqs_on() text_poke_early()     apply_alternatives() ... On machines with 5-level paging, cpu_feature_enabled(X86_FEATURE_LA57) gets     patched. It includes KASAN code, where KASAN_SHADOW_START depends on __VIRTUAL_MASK_SHIFT, which is     defined with cpu_feature_enabled(). KASAN gets confused when apply_alternatives() patches the     KASAN_SHADOW_START users. A test patch that makes KASAN_SHADOW_START static, by replacing
    __VIRTUAL_MASK_SHIFT with 56, works around the issue. Fix it for real by disabling KASAN while the kernel     is patching alternatives. [ mingo: updated the changelog ] (CVE-2023-52504)

  - In the Linux kernel, the following vulnerability has been resolved: drm/amd: Fix UBSAN array-index-out-of-     bounds for SMU7 For pptable structs that use flexible array sizes, use flexible arrays. (CVE-2023-52818)

  - In the Linux kernel, the following vulnerability has been resolved: nbd: defer config unlock in     nbd_genl_connect There is one use-after-free warning when running NBD_CMD_CONNECT and NBD_CLEAR_SOCK:
    nbd_genl_connect nbd_alloc_and_init_config // config_refs=1 nbd_start_device // config_refs=2 set     NBD_RT_HAS_CONFIG_REF open nbd // config_refs=3 recv_work done // config_refs=2 NBD_CLEAR_SOCK //     config_refs=1 close nbd // config_refs=0 refcount_inc -> uaf ------------[ cut here ]------------     refcount_t: addition on 0; use-after-free.

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: ASoC: SOF: debug: Fix potential buffer     overflow by snprintf() snprintf() returns the would-be-filled size when the string overflows the given     buffer size, hence using this value may result in the buffer overflow (although it's unrealistic). This     patch replaces with a safer version, scnprintf() for papering over such a potential issue.
    (CVE-2022-50051)

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

The CentOS Linux 8.4 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.4:CLSA-2026:1782145985 advisory.

  - Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory     entry lists. (CVE-2019-10220)

  - 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)

  - The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. (CVE-2019-7221)

  - This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel     5.14-rc3. An attacker must first obtain the ability to execute low-privileged code on the target system in     order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The     issue results from the lack of proper validation of user-supplied eBPF programs, which can result in a     type confusion condition. An attacker can leverage this vulnerability to escalate privileges and execute     arbitrary code in the context of the kernel. Was ZDI-CAN-14689. (CVE-2021-34866)

  - In the Linux kernel, the following vulnerability has been resolved: kyber: fix out of bounds access when     preempted __blk_mq_sched_bio_merge() gets the ctx and hctx for the current CPU and passes the hctx to
    ->bio_merge(). kyber_bio_merge() then gets the ctx for the current CPU again and uses that to get the     corresponding Kyber context in the passed hctx. However, the thread may be preempted between the two calls     to blk_mq_get_ctx(), and the ctx returned the second time may no longer correspond to the passed hctx.
    This works accidentally most of the time, but it can cause us to read garbage if the second ctx came     from an hctx with more ctx's than the first one (i.e., if ctx->index_hw[hctx->type] > hctx->nr_ctx). This     manifested as this UBSAN array index out of bounds error reported by Jakub: UBSAN: array-index-out-of-     bounds in ../kernel/locking/qspinlock.c:130:9 index 13106 is out of range for type 'long unsigned int     [128]' Call Trace: dump_stack+0xa4/0xe5 ubsan_epilogue+0x5/0x40

BFQ and mq-deadline just use that, and Kyber can map the queues itself to avoid the mismatch.
