In the Linux kernel, the following vulnerability has been resolved: drm/i915: Fix NULL ptr deref by checking new_crtc_state intel_atomic_get_new_crtc_state can return NULL, unless crtc state wasn't obtained previously with intel_atomic_get_crtc_state, so we must check it for NULLness here, just as in many other places, where we can't guarantee that intel_atomic_get_crtc_state was called. We are currently getting NULL ptr deref because of that, so this fix was confirmed to help. (cherry picked from commit 1d5b09f8daf859247a1ea65b0d732a24d88980d8)

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

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1767864313 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scpi: Ensure scpi_info     is not assigned if the probe fails When scpi probe fails, at any point, we need to ensure that the     scpi_info is not set and will remain NULL until the probe succeeds. If it is not taken care, then it could     result use-after-free as the value is exported via get_scpi_ops() and could refer to a memory allocated     via devm_kzalloc() but freed when the probe fails. (CVE-2022-50087)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: Fix global-out-of-     bounds bug in _rtl8812ae_phy_set_txpower_limit() There is a global-out-of-bounds reported by KASAN: BUG:

    </TASK> The root cause of the problem is that the comparison order of prate_section in
    _rtl8812ae_phy_set_txpower_limit() is wrong. The _rtl8812ae_eq_n_byte() is used to compare the first n     bytes of the two strings from tail to head, which causes the problem. In the
    _rtl8812ae_phy_set_txpower_limit(), it was originally intended to meet this requirement by carefully     designing the comparison order. For example, pregulation and pbandwidth are compared in order of     length from small to large, first is 3 and last is 4. However, the comparison order of prate_section     dose not obey such order requirement, therefore when prate_section is HT, when comparing from tail to     head, it will lead to access out of bounds in _rtl8812ae_eq_n_byte(). As mentioned above, the
    _rtl8812ae_eq_n_byte() has the same function as strcmp(), so just strcmp() is enough. Fix it by removing
    _rtl8812ae_eq_n_byte() and use strcmp() barely. Although it can be fixed by adjusting the comparison order     of prate_section, this may cause the value of rate_section to not be from 0 to 5. In addition, commit     21e4b0726dc6 not only moved driver from staging to regular tree, but also added setting txpower limit     function during the driver config phase, so the problem was introduced by this commit.

  - In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix monitor mode bringup     crash When the interface is brought up in monitor mode, it leads to NULL pointer dereference crash.

  - In the Linux kernel, the following vulnerability has been resolved: PCI: Fix pci_device_is_present() for     VFs by checking PF pci_device_is_present() previously didn't work for VFs because it reads the Vendor and     Device ID, which are 0xffff for VFs, which looks like they aren't present. Check the PF instead. Wei Gong     reported that if virtio I/O is in progress when the driver is unbound or 0 is written to     /sys/.../sriov_numvfs, the virtio I/O operation hangs, which may result in output like this: task:bash     state:D stack: 0 pid: 1773 ppid: 1241 flags:0x00004002 Call Trace: schedule+0x4f/0xc0     blk_mq_freeze_queue_wait+0x69/0xa0 blk_mq_freeze_queue+0x1b/0x20 blk_cleanup_queue+0x3d/0xd0     virtblk_remove+0x3c/0xb0 [virtio_blk] virtio_dev_remove+0x4b/0x80 ... device_unregister+0x1b/0x60     unregister_virtio_device+0x18/0x30 virtio_pci_remove+0x41/0x80 pci_device_remove+0x3e/0xb0 This happened     because pci_device_is_present(VF) returned false in virtio_pci_remove(), so it called     virtio_break_device().

Tenable has extracted the preceding description block directly from the SUSE 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - drm/i915: Fix NULL ptr deref by checking new_crtc_state intel_atomic_get_new_crtc_state can return NULL,     unless crtc state wasn't obtained previously with intel_atomic_get_crtc_state, so we must check it for     NULLness here, just as in many other places, where we can't guarantee that intel_atomic_get_crtc_state was     called. We are currently getting NULL ptr deref because of that, so this fix was confirmed to help.
    (cherry picked from commit 1d5b09f8daf859247a1ea65b0d732a24d88980d8) (CVE-2023-53833)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-228 advisory.

    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:

    binder: fix UAF of alloc->vma in race with munmap() (CVE-2022-50338)

    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 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)
