The remote Ubuntu 23.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6818-2 advisory.

    Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C     PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a     denial of service (system crash). (CVE-2023-6356, CVE-2023-6535, CVE-2023-6536)

    It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux     kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker     could use this to cause a denial of service. (CVE-2024-21823)

    Chenyuan Yang discovered that the RDS Protocol implementation in the Linux kernel contained an out-of-     bounds read vulnerability. An attacker could use this to possibly cause a denial of service (system     crash). (CVE-2024-23849)

    It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel, leading to     a null pointer dereference vulnerability. A privileged local attacker could use this to possibly cause a     denial of service (system crash). (CVE-2024-24860)

  - In the Linux kernel, the following vulnerability has been resolved: extcon: Modify extcon device to be     created after driver data is set Currently, someone can invoke the sysfs such as state_show()     intermittently before dev_set_drvdata() is done. And it can be a cause of kernel Oops because of edev is     Null at that time. So modified the driver registration to after setting drviver data. - Oops's backtrace.

  - In the Linux kernel, the following vulnerability has been resolved: tick/nohz: unexport __init-annotated     tick_nohz_full_setup() EXPORT_SYMBOL and __init is a bad combination because the .init.text section is     freed up after the initialization. Hence, modules cannot use symbols annotated __init. The access to a     freed symbol may end up with kernel panic. modpost used to detect it, but it had been broken for a decade.
    Commit 28438794aba4 (modpost: fix section mismatch check for exported init/exit sections) fixed it so     modpost started to warn it again, then this showed up: MODPOST vmlinux.symvers WARNING: modpost:
    vmlinux.o(___ksymtab_gpl+tick_nohz_full_setup+0x0): Section mismatch in reference from the variable
    __ksymtab_tick_nohz_full_setup to the function .init.text:tick_nohz_full_setup() The symbol     tick_nohz_full_setup is exported and annotated __init Fix this by removing the __init annotation of     tick_nohz_full_setup or drop the export. Drop the export because tick_nohz_full_setup() is only called     from the built-in code in kernel/sched/isolation.c. (CVE-2022-49675)

  - In the Linux kernel, the following vulnerability has been resolved: ata: libata-core: fix NULL pointer     deref in ata_host_alloc_pinfo() In an unlikely (and probably wrong?) case that the 'ppi' parameter of     ata_host_alloc_pinfo() points to an array starting with a NULL pointer, there's going to be a kernel oops     as the 'pi' local variable won't get reassigned from the initial value of NULL. Initialize 'pi' instead to     '&ata_dummy_port_info' to fix the possible kernel oops for good... Found by Linux Verification Center     (linuxtesting.org) with the SVACE static analysis tool. (CVE-2022-49731)

  - In the Linux kernel, the following vulnerability has been resolved: bridge: switchdev: Fix memory leaks     when changing VLAN protocol The bridge driver can offload VLANs to the underlying hardware either via     switchdev or the 8021q driver. When the former is used, the VLAN is marked in the bridge driver with the     'BR_VLFLAG_ADDED_BY_SWITCHDEV' private flag. To avoid the memory leaks mentioned in the cited commit, the     bridge driver will try to delete a VLAN via the 8021q driver if the VLAN is not marked with the previously     mentioned flag. When the VLAN protocol of the bridge changes, switchdev drivers are notified via the     'SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL' attribute, but the 8021q driver is also called to add the     existing VLANs with the new protocol and delete them with the old protocol. In case the VLANs were     offloaded via switchdev, the above behavior is both redundant and buggy. Redundant because the VLANs are     already programmed in hardware and drivers that support VLAN protocol change (currently only mlx5) change     the protocol upon the switchdev attribute notification. Buggy because the 8021q driver is called despite     these VLANs being marked with 'BR_VLFLAG_ADDED_BY_SWITCHDEV'. This leads to memory leaks [1] when the     VLANs are deleted.

  - In the Linux kernel, the following vulnerability has been resolved: capabilities: fix potential memleak on     error path from vfs_getxattr_alloc() In cap_inode_getsecurity(), we will use vfs_getxattr_alloc() to     complete the memory allocation of tmpbuf, if we have completed the memory allocation of tmpbuf, but failed     to call handler->get(...), there will be a memleak in below logic: |-- ret =     (int)vfs_getxattr_alloc(mnt_userns, ...) | /* ^^^ alloc for tmpbuf */ |-- value = krealloc(*xattr_value,     error + 1, flags) | /* ^^^ alloc memory */ |-- error = handler->get(handler, ...) | /* error! */ |--
    *xattr_value = value | /* xattr_value is &tmpbuf (memory leak!) */ So we will try to free(tmpbuf) after     vfs_getxattr_alloc() fails to fix it. [PM: subject line and backtrace tweaks] (CVE-2022-49890)

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

    A flaw has been found in Xen. An unprivileged guest can cause Denial of Service (DoS) of the host by     sending network packets to the backend, causing the backend to crash. (CVE-2023-46838)

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

    uio: Fix use-after-free in uio_open

    core-1                          core-2-------------------------------------------------------     uio_unregister_device              uio_openidev = idr_find()device_unregister(&idev->dev)put_device(&idev-     >dev)uio_device_releaseget_device(&idev->dev)kfree(idev)uio_free_minor(minor)uio_releaseput_device(&idev-     >dev)kfree(idev)-------------------------------------------------------

    In the core-1 uio_unregister_device(), the device_unregister will kfreeidev when the idev->dev kobject ref     is 1. But after core-1device_unregister, put_device and before doing kfree, the core-2 mayget_device.
    Then:1. After core-1 kfree idev, the core-2 will do use-after-free for idev.2. When core-2 do uio_release     and put_device, the idev will be doublefreed.

    To address this issue, we can get idev atomic & inc idev reference withminor_lock. (CVE-2023-52439)

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

    gfs2: Fix kernel NULL pointer dereference in gfs2_rgrp_dump

    Syzkaller has reported a NULL pointer dereference when accessingrgd->rd_rgl in gfs2_rgrp_dump().  This can     happen when creatingrgd->rd_gl fails in read_rindex_entry().  Add a NULL pointer check ingfs2_rgrp_dump()     to prevent that. (CVE-2023-52448)

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

    EDAC/thunderx: Fix possible out-of-bounds string access

    Enabling -Wstringop-overflow globally exposes a warning for a common bugin the usage of strncat():

    drivers/edac/thunderx_edac.c: In function     'thunderx_ocx_com_threaded_isr':drivers/edac/thunderx_edac.c:1136:17: error: 'strncat' specified bound     1024 equals destination size [-Werror=stringop-overflow=]1136 |                 strncat(msg, other,     OCX_MESSAGE_SIZE);|                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~...1145 |     strncat(msg, other, OCX_MESSAGE_SIZE);...1150 |                                 strncat(msg, other,     OCX_MESSAGE_SIZE);

    ...

    Apparently the author of this driver expected strncat() to behave theway that strlcat() does, which uses     the size of the destination bufferas its third argument rather than the length of the source buffer.
    Theresult is that there is no check on the size of the allocated buffer.

    Change it to strlcat().

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

    drivers/amd/pm: fix a use-after-free in kv_parse_power_table

    When ps allocated by kzalloc equals to NULL, kv_parse_power_tablefrees adev->pm.dpm.ps that allocated     before. However, after the controlflow goes through the following call chains:

    kv_parse_power_table|-> kv_dpm_init|-> kv_dpm_sw_init|-> kv_dpm_fini

    The adev->pm.dpm.ps is used in the for loop of kv_dpm_fini after itsfirst free in kv_parse_power_table and     causes a use-after-free bug. (CVE-2023-52469)

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

    drm/radeon: check the alloc_workqueue return value in radeon_crtc_init()

    check the alloc_workqueue return value in radeon_crtc_init()to avoid null-ptr-deref. (CVE-2023-52470)

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

    crypto: scomp - fix req->dst buffer overflow (CVE-2023-52612)

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

    calipso: fix memory leak in netlbl_calipso_add_pass() (CVE-2023-52698)

    An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4     (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of     a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an     attacker to achieve out-of-bounds access. (CVE-2023-6040)

    A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two     threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline     enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This     could allow a local unprivileged user to escalate their privileges on the system. (CVE-2023-6546)

    A Null pointer dereference problem was found in ida_free in lib/idr.c in the Linux Kernel. This issue may     allow an attacker using this library to cause a denial of service problem due to a missing check at a     function return. (CVE-2023-6915)

    An out-of-bounds memory read flaw was found in receive_encrypted_standard in fs/smb/client/smb2ops.c in     the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy     length, leading to a denial of service. (CVE-2024-0565)

    netfilter: nf_tables: fix pointer math issue in nft_byteorder_eval() (CVE-2024-0607)

    An out-of-bounds memory write flaw was found in the Linux kernel's Transport Layer Security functionality     in how a user calls a function splice with a ktls socket as the destination. This flaw allows a local user     to crash or potentially escalate their privileges on the system. (CVE-2024-0646)

    In rds_recv_track_latency in net/rds/af_rds.c in the Linux kernel through 6.7.1, there is an off-by-one     error for an RDS_MSG_RX_DGRAM_TRACE_MAX comparison, resulting in out-of-bounds access. (CVE-2024-23849)

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

    ip6_tunnel: fix NEXTHDR_FRAGMENT handling in ip6_tnl_parse_tlv_enc_lim() (CVE-2024-26633)
