The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:0484-1 advisory.

  - Integer Overflow or Wraparound vulnerability in openEuler kernel on Linux (filesystem modules) allows     Forced Integer Overflow.This issue affects openEuler kernel: from 4.19.90 before 4.19.90-2401.3, from     5.10.0-60.18.0 before 5.10.0-183.0.0. (CVE-2021-33631)

  - Transmit requests in Xen's virtual network protocol can consist of multiple parts. While not really     useful, except for the initial part any of them may be of zero length, i.e. carry no data at all. Besides     a certain initial portion of the to be transferred data, these parts are directly translated into what     Linux calls SKB fragments. Such converted request parts can, when for a particular SKB they are all of     length zero, lead to a de-reference of NULL in core networking code. (CVE-2023-46838)

  - The brcm80211 component in the Linux kernel through 6.5.10 has a brcmf_cfg80211_detach use-after-free in     the device unplugging (disconnect the USB by hotplug) code. For physically proximate attackers with local     access, this could be exploited in a real world scenario. This is related to     brcmf_cfg80211_escan_timeout_worker in drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c.
    (CVE-2023-47233)

  - In the Linux kernel before 6.4.12, amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c has     a fence use-after-free. (CVE-2023-51042)

  - In the Linux kernel before 6.4.5, drivers/gpu/drm/drm_atomic.c has a use-after-free during a race     condition between a nonblocking atomic commit and a driver unload. (CVE-2023-51043)

  - An issue was discovered in the Linux kernel before 6.6.8. do_vcc_ioctl in net/atm/ioctl.c has a use-after-     free because of a vcc_recvmsg race condition. (CVE-2023-51780)

  - An issue was discovered in the Linux kernel before 6.6.8. rose_ioctl in net/rose/af_rose.c has a use-     after-free because of a rose_accept race condition. (CVE-2023-51782)

  - 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 flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious     actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL     pointer dereference in the NVMe driver and causing kernel panic and a denial of service. (CVE-2023-6356)

  - A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious     actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL     pointer dereference in the NVMe driver, causing kernel panic and a denial of service. (CVE-2023-6535,     CVE-2023-6536)

  - An out-of-bounds read vulnerability was found in smb2_dump_detail in fs/smb/client/smb2ops.c in the Linux     Kernel. This issue could allow a local attacker to crash the system or leak internal kernel information.
    (CVE-2023-6610)

  - A vulnerability was found in vhost_new_msg in drivers/vhost/vhost.c in the Linux kernel, which does not     properly initialize memory in messages passed between virtual guests and the host operating system in the     vhost/vhost.c:vhost_new_msg() function. This issue can allow local privileged users to read some kernel     memory contents when reading from the /dev/vhost-net device file. (CVE-2024-0340)

  - A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This     flaw allows a local user to cause an information leak problem while freeing the old quota file names     before a potential failure, leading to a use-after-free. (CVE-2024-0775)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error     within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when     NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit     f342de4e2f33e0e39165d8639387aa6c19dff660. (CVE-2024-1086)

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