    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)

  - An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The     userspace data->block[0] variable was not capped to a number between 0-255 and was used as the size of a     memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to     crash the system or potentially achieve code execution. (CVE-2023-2194)

  - Due to a vulnerability in the io_uring subsystem, it is possible to leak kernel memory information to the     user process. timens_install calls current_is_single_threaded to determine if the current process is     single-threaded, but this call does not consider io_uring's io_worker threads, thus it is possible to     insert a time namespace's vvar page to process's memory space via a page fault. When this time namespace     is destroyed, the vvar page is also freed, but not removed from the process' memory, and a next page     allocated by the kernel will be still available from the user-space process and can leak memory contents     via this (read-only) use-after-free vulnerability. We recommend upgrading past version 5.10.161 or commit     788d0824269bef539fe31a785b1517882eafed93     https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/io_uring (CVE-2023-23586)

  - A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors. (CVE-2023-2513)

  - 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)

  - qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX. (CVE-2023-31436)

  - In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests     can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users     can obtain root privileges. This occurs because anonymous sets are mishandled. (CVE-2023-32233)

  - An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-     after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order     for an attacker to exploit this, the system must have netrom routing configured or the attacker must have     the CAP_NET_ADMIN capability. (CVE-2023-32269)

  - An issue was discovered in the Linux kernel before 6.2.9. A use-after-free was found in bq24190_remove in     drivers/power/supply/bq24190_charger.c. It could allow a local attacker to crash the system due to a race     condition. (CVE-2023-33288)

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 packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2501-1 advisory.

  - A vulnerability, which was classified as problematic, was found in Linux Kernel. This affects the function     tcp_getsockopt/tcp_setsockopt of the component TCP Handler. The manipulation leads to race condition. It     is recommended to apply a patch to fix this issue. The identifier VDB-211089 was assigned to this     vulnerability. (CVE-2022-3566)

  - 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_frontend.c has a     race condition that can cause a use-after-free when a device is disconnected. (CVE-2022-45885)

  - 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 6.0.9. drivers/media/usb/ttusb-dec/ttusb_dec.c has a     memory leak because of the lack of a dvb_frontend_detach call. (CVE-2022-45887)

  - 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 slab-out-of-bound read problem was found in brcmf_get_assoc_ies in     drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux Kernel. This issue could occur     when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading     to a denial of service. (CVE-2023-1380)

  - A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA in the Linux     Kernel. The improper cleanup results in out-of-boundary read, where a local user can utilize this problem     to crash the system or escalation of privilege. (CVE-2023-2176)

  - An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The     userspace data->block[0] variable was not capped to a number between 0-255 and was used as the size of a     memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to     crash the system or potentially achieve code execution. (CVE-2023-2194)

  - 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 vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors. (CVE-2023-2513)

  - do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference). (CVE-2023-28466)

  - 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)

  - qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX. (CVE-2023-31436)

  - An issue was discovered in the Linux kernel before 6.1.11. In net/netrom/af_netrom.c, there is a use-     after-free because accept is also allowed for a successfully connected AF_NETROM socket. However, in order     for an attacker to exploit this, the system must have netrom routing configured or the attacker must have     the CAP_NET_ADMIN capability. (CVE-2023-32269)
