The remote Ubuntu 23.04 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6283-1 advisory.

  - A vulnerability was found in the HCI sockets implementation due to a missing capability check in     net/bluetooth/hci_sock.c in the Linux Kernel. This flaw allows an attacker to unauthorized execution of     management commands, compromising the confidentiality, integrity, and availability of Bluetooth     communication. (CVE-2023-2002)

  - A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

  - A use-after-free flaw was found in r592_remove in drivers/memstick/host/r592.c in media access in the     Linux Kernel. This flaw allows a local attacker to crash the system at device disconnect, possibly leading     to a kernel information leak. (CVE-2023-3141)

  - A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw     exists within the handling of SMB2_TREE_CONNECT and SMB2_QUERY_INFO commands. The issue results from the     lack of proper validation of a pointer prior to accessing it. An attacker can leverage this vulnerability     to create a denial-of-service condition on the system. (CVE-2023-32248)

  - A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw     exists within the processing of SMB2_TREE_DISCONNECT commands. The issue results from the lack of proper     locking when performing operations on an object. An attacker can leverage this vulnerability to execute     code in the context of the kernel. (CVE-2023-32254)

  - An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

  - A vulnerability was found in drivers/cpufreq/qcom-cpufreq-hw.c in cpufreq subsystem in the Linux Kernel.
    This flaw, during device unbind will lead to double release problem leading to denial of service.
    (CVE-2023-3312)

  - A use-after-free flaw was found in mt7921_check_offload_capability in     drivers/net/wireless/mediatek/mt76/mt7921/init.c in wifi mt76/mt7921 sub-component in the Linux Kernel.
    This flaw could allow an attacker to crash the system after 'features' memory release. This vulnerability     could even lead to a kernel information leak problem. (CVE-2023-3317)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in saa7134_finidev in     drivers/media/pci/saa7134/saa7134-core.c. (CVE-2023-35823)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in dm1105_remove in     drivers/media/pci/dm1105/dm1105.c. (CVE-2023-35824)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in cedrus_remove in     drivers/staging/media/sunxi/cedrus/cedrus.c. (CVE-2023-35826)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in     renesas_usb3_remove in drivers/usb/gadget/udc/renesas_usb3.c. (CVE-2023-35828)

  - An issue was discovered in the Linux kernel before 6.3.2. A use-after-free was found in rkvdec_remove in     drivers/staging/media/rkvdec/rkvdec.c. (CVE-2023-35829)

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

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5448 advisory.

  - An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores     an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or     potentially escalate their privileges on the system. (CVE-2023-2124)

  - A flaw was found in the networking subsystem of the Linux kernel within the handling of the RPL protocol.
    This issue results from the lack of proper handling of user-supplied data, which can lead to an assertion     failure. This may allow an unauthenticated remote attacker to create a denial of service condition on the     system. (CVE-2023-2156)

  - A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component. (CVE-2023-2269)

  - 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)

  - An issue was discovered in drivers/media/dvb-core/dvb_frontend.c in the Linux kernel 6.2. There is a     blocking operation when a task is in !TASK_RUNNING. In dvb_frontend_get_event, wait_event_interruptible is     called; the condition is dvb_frontend_test_event(fepriv,events). In dvb_frontend_test_event,     down(&fepriv->sem) is called. However, wait_event_interruptible would put the process to sleep, and     down(&fepriv->sem) may block the process. (CVE-2023-31084)

  - A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on     corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it     has been freed and set to NULL. A privileged local user could use this flaw to cause a kernel panic.
    (CVE-2023-3212)

  - An out of bounds (OOB) memory access flaw was found in the Linux kernel in relay_file_read_start_pos in     kernel/relay.c in the relayfs. This flaw could allow a local attacker to crash the system or leak kernel     internal information. (CVE-2023-3268)

  - 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 commit     1240eb93f0616b21c675416516ff3d74798fdc97. (CVE-2023-3390)

  - 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)

  - distros-[DirtyVMA] Privilege escalation via non-RCU-protected VMA traversal [fedora-all] (CVE-2023-3269)
