The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3892-1 advisory.

  - A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited     to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate     filters in case of a perfect hashes while deleting the underlying structure which can later lead to double     freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.
    We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. (CVE-2023-1829)

  - Linux Kernel nftables Use-After-Free Local Privilege Escalation Vulnerability; `nft_chain_lookup_byid()`     failed to check whether a chain was active and CAP_NET_ADMIN is in any user or network namespace     (CVE-2023-31248)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return     an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.
    (CVE-2023-3609)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.
    (CVE-2023-3776)

  - An out-of-bounds memory access flaw was found in the Linux kernel's TUN/TAP device driver functionality in     how a user generates a malicious (too big) networking packet when napi frags is enabled. This flaw allows     a local user to crash or potentially escalate their privileges on the system. (CVE-2023-3812)

  - A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation     of the file name reconstruction function, which is responsible for reading file name entries from a     directory index and merging file name parts belonging to one file into a single long file name. Since the     file name characters are copied into a stack variable, a local privileged attacker could use this flaw to     overflow the kernel stack. (CVE-2023-4273)

    * kernel: tun: bugs for oversize packet when napi frags enabled in tun_napi_alloc_frags (CVE-2023-3812)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

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

  - An out-of-bounds memory access flaw was found in the Linux kernel's TUN/TAP device driver functionality in     how a user generates a malicious (too big) networking packet when napi frags is enabled. This flaw allows     a local user to crash or potentially escalate their privileges on the system. (CVE-2023-3812)

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

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2023:7549 advisory.

  - An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvbdev.c has a use-     after-free, related to dvb_register_device dynamically allocating fops. (CVE-2022-45884)

  - An issue was discovered in the Linux kernel through 6.0.9. drivers/media/dvb-core/dvb_net.c has a     .disconnect versus dvb_device_open race condition that leads to a use-after-free. (CVE-2022-45886)

  - An issue was discovered in the Linux kernel through 6.0.10. In drivers/media/dvb-core/dvb_ca_en50221.c, a     use-after-free can occur is there is a disconnect after an open, because of the lack of a wait_event.
    (CVE-2022-45919)

  - A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS     transfers response data to a system call, there are still local variable points to the memory region, and     if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a     denial of service. (CVE-2023-1192)

  - Incorrect verifier pruning in BPF in Linux Kernel >=5.4 leads to unsafe code paths being incorrectly     marked as safe, resulting in arbitrary read/write in kernel memory, lateral privilege escalation, and     container escape. (CVE-2023-2163)

  - An out-of-bounds memory access flaw was found in the Linux kernel's TUN/TAP device driver functionality in     how a user generates a malicious (too big) networking packet when napi frags is enabled. This flaw allows     a local user to crash or potentially escalate their privileges on the system. (CVE-2023-3812)

  - A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a     logical bug in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a malicious local     privileged user to cause a use-after-free and double-free problem, which may permit remote code execution     or lead to local privilege escalation problem. (CVE-2023-5178)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote SUSE Linux SLES12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3749-1 advisory.

  - A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited     to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate     filters in case of a perfect hashes while deleting the underlying structure which can later lead to double     freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.
    We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. (CVE-2023-1829)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return     an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 04c55383fa5689357bcdd2c8036725a55ed632bc.
    (CVE-2023-3609)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.

This flaw allows     a local user to crash or potentially escalate their privileges on the system. (CVE-2023-3812)

  - A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation     of the file name reconstruction function, which is responsible for reading file name entries from a     directory index and merging file name parts belonging to one file into a single long file name. Since the     file name characters are copied into a stack variable, a local privileged attacker could use this flaw to     overflow the kernel stack. (CVE-2023-4273)
