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

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

    A use-after-free flaw was found in vmxnet3_rq_alloc_rx_buf in drivers/net/vmxnet3/vmxnet3_drv.c in     VMware's vmxnet3 ethernet NIC driver in the Linux Kernel. This issue could allow a local attacker to crash     the system due to a double-free while cleaning up vmxnet3_rq_cleanup_all, which could also lead to a     kernel information leak problem.(CVE-2023-4387)

    A NULL pointer dereference flaw was found in vmxnet3_rq_cleanup in drivers/net/vmxnet3/vmxnet3_drv.c in     the networking sub-component in vmxnet3 in the Linux Kernel. This issue may allow a local attacker with     normal user privilege to cause a denial of service due to a missing sanity check during     cleanup.(CVE-2023-4459)

    A NULL pointer dereference flaw was found in dbFree in fs/jfs/jfs_dmap.c in the journaling file system     (JFS) in the Linux Kernel. This issue may allow a local attacker to crash the system due to a missing     sanity check.(CVE-2023-4385)

    A use-after-free vulnerability was found in the siano smsusb module in the Linux kernel. The bug occurs     during device initialization when the siano device is plugged in. This flaw allows a local user to crash     the system, causing a denial of service condition.(CVE-2023-4132)

    A buffer overrun vulnerability was found in the netback driver in Xen due to an unusual split packet. This     flaw allows an unprivileged guest to cause a denial of service (DoS) of the host by sending network     packets to the backend, causing the backend to crash.(CVE-2023-34319)

    A use-after-free flaw was found in nfc_llcp_find_local in net/nfc/llcp_core.c in NFC in the Linux kernel.
    This flaw allows a local user with special privileges to impact a kernel information leak     issue.(CVE-2023-3863)

    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)

    In multiple functions of binder.c, there is a possible memory corruption due to a use after free. This     could lead to local escalation of privilege with no additional execution privileges needed. User     interaction is not needed for exploitation.(CVE-2023-21255)

    A null pointer dereference flaw was found in the Linux kernel's DECnet networking protocol. This issue     could allow a remote user to crash the system.(CVE-2023-3338)

    A null pointer dereference was found in the Linux kernel's Integrated Sensor Hub (ISH) driver. This issue     could allow a local user to crash the system.(CVE-2023-3358)

    A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in     the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to     incorrect handling of the existing filter, leading to a kernel information leak issue.(CVE-2023-4128)

    A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to     bypass network filters and gain unauthorized access to some resources. The original patches fixing     CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits -     a096ccca6e50 ('tun: tun_chr_open(): correctly initialize socket uid'), - 66b2c338adce ('tap: tap_open():
    correctly initialize socket uid'), pass 'inode-i_uid' to sock_init_data_uid() as the last parameter and     that turns out to not be accurate.(CVE-2023-4194)

    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)

    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 flaw was found in the Linux kernels 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)

    An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation.The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-     of-bounds write because lmax is updated according to packet sizes without bounds checks.We recommend     upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64.(CVE-2023-3611)

    Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace(CVE-2023-35001)

    A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in     net/netfilter/nf_tables_api.c.Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a     dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local     attacker with user access to cause a privilege escalation issue.We recommend upgrading past     commit1240eb93f0616b21c675416516ff3d74798fdc97.(CVE-2023-3390)

    A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernels IPv6     functionality when a user makes a new kind of SYN flood attack. A user located in the local network or     with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up     to 95%.(CVE-2023-1206)

The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3392-1 advisory.

  - Information exposure through microarchitectural state after transient execution in certain vector     execution units for some Intel(R) Processors may allow an authenticated user to potentially enable     information disclosure via local access. (CVE-2022-40982)

  - Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec     allowing a user to bypass the access_ok check and pass a kernel pointer to copy_from_user(). This would     allow an attacker to leak information. We recommend upgrading beyond commit     74e19ef0ff8061ef55957c3abd71614ef0f42f47 (CVE-2023-0459)

  - A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address     prediction. This may result in speculative execution at an attacker-controlled?address, potentially     leading to information disclosure. (CVE-2023-20569)

  - An issue in Zen 2 CPUs, under specific microarchitectural circumstances, may allow an attacker to     potentially access sensitive information. (CVE-2023-20593)

  - A use after free flaw was found in hfsplus_put_super in fs/hfsplus/super.c in the Linux Kernel. This flaw     could allow a local user to cause a denial of service problem. (CVE-2023-2985)

  - A flaw in the Linux Kernel found in the GFS2 file system. On corrupted gfs2 file systems the evict code     can try to reference the journal descriptor structure, jdesc, after it has been freed and set to NULL. It     can lead to null pointer dereference when gfs2_trans_begin being called and then fail     ingfs2_evict_inode(). (CVE-2023-3212) (CVE-2023-34319)

  - Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register     contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001)

  - A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. This flaw allows an attacker with local user access to cause a system crash or leak internal     kernel information. (CVE-2023-3567)

  - 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)

  - An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-     of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend     upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. (CVE-2023-3611)

  - 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)

  - A use-after-free vulnerability was found in the cxgb4 driver in the Linux kernel. The bug occurs when the     cxgb4 device is detaching due to a possible rearming of the flower_stats_timer from the work queue. This     flaw allows a local user to crash the system, causing a denial of service condition. (CVE-2023-4133)

  - A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to     bypass network filters and gain unauthorized access to some resources. The original patches fixing     CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits -     a096ccca6e50 (tun: tun_chr_open(): correctly initialize socket uid), - 66b2c338adce (tap: tap_open():
    correctly initialize socket uid), pass inode->i_uid to sock_init_data_uid() as the last parameter and     that turns out to not be accurate. (CVE-2023-4194)

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    CVE-2022-4269

        William Zhao discovered that a flaw in the Traffic Control (TC)         subsystem when using a specific networking configuration         (redirecting egress packets to ingress using TC action mirred),         may allow a local unprivileged user to cause a denial of service         (triggering a CPU soft lockup).

    CVE-2022-39189

        Jann Horn discovered that TLB flush operations are mishandled in         the KVM subsystem in certain KVM_VCPU_PREEMPTED situations, which         may allow an unprivileged guest user to compromise the guest         kernel.

    CVE-2023-1206

        It was discovered that the networking stack permits attackers to         force hash collisions in the IPv6 connection lookup table, which         may result in denial of service (significant increase in the cost         of lookups, increased CPU utilization).

    CVE-2023-1380

        Jisoo Jang reported a heap out-of-bounds read in the brcmfmac         Wi-Fi driver. On systems using this driver, a local user could         exploit this to read sensitive information or to cause a denial of         service.

    CVE-2023-2002

        Ruiahn Li reported an incorrect permissions check in the Bluetooth         subsystem. A local user could exploit this to reconfigure local         Bluetooth interfaces, resulting in information leaks, spoofing, or         denial of service (loss of connection).

    CVE-2023-2007

        Lucas Leong and Reno Robert discovered a         time-of-check-to-time-of-use flaw in the dpt_i2o SCSI controller         driver. A local user with access to a SCSI device using this         driver could exploit this for privilege escalation.

        This flaw has been mitigated by removing support for the I2OUSRCMD         operation.

    CVE-2023-2124

        Kyle Zeng, Akshay Ajayan and Fish Wang discovered that missing         metadata validation may result in denial of service or potential         privilege escalation if a corrupted XFS disk image is mounted.

    CVE-2023-2269

        Zheng Zhang reported that improper handling of locking in the         device mapper implementation may result in denial of service.

    CVE-2023-2898

        It was discovered that missing sanitising in the f2fs file system         may result in denial of service if a malformed file system is         accessed.

    CVE-2023-3090

        It was discovered that missing initialization in ipvlan networking         may lead to an out-of-bounds write vulnerability, resulting in         denial of service or potentially the execution of arbitrary code.

    CVE-2023-3111

        The TOTE Robot tool found a flaw in the Btrfs filesystem driver         that can lead to a use-after-free. It's unclear whether an         unprivileged user can exploit this.

    CVE-2023-3141

        A flaw was discovered in the r592 memstick driver that could lead         to a use-after-free after the driver is removed or unbound from a         device. The security impact of this is unclear.

    CVE-2023-3212

        Yang Lan discovered that missing validation in the GFS2 filesystem         could result in denial of service via a NULL pointer dereference         when mounting a malformed GFS2 filesystem.

    CVE-2023-3268

        It was discovered that an out-of-bounds memory access in relayfs         could result in denial of service or an information leak.

    CVE-2023-3338

        Davide Ornaghi discovered a flaw in the DECnet protocol         implementation which could lead to a null pointer dereference or         use-after-free. A local user can exploit this to cause a denial of         service (crash or memory corruption) and probably for privilege         escalation.

Tenable has extracted the preceding description block directly from the Ubuntu 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 fix for XSA-423 added logic to Linux'es netback driver to deal with a frontend splitting a packet in a way such that not all of the headers would come in one piece.  Unfortunately the logic introduced there didn't account for the extreme case of the entire packet being split into as many pieces as permitted by the protocol, yet still being smaller than the area that's specially dealt with to keep all (possible) headers together.  Such an unusual packet would therefore trigger a buffer overrun in the driver.
