"The remote SUSE Linux SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in
the SUSE-SU-2024:0476-1 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)

  - 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)

  - 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)

  - 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)

  - A denial of service vulnerability was found in tipc_crypto_key_revoke in net/tipc/crypto.c in the Linux
    kernel's TIPC subsystem. This flaw allows guests with local user privileges to trigger a deadlock and
    potentially crash the system. (CVE-2024-0641)

  - 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_setelem_catchall_deactivate() function checks whether the
    catch-all set element is active in the current generation instead of the next generation before freeing
    it, but only flags it inactive in the next generation, making it possible to free the element multiple
    times, leading to a double free vulnerability. We recommend upgrading past commit
    b1db244ffd041a49ecc9618e8feb6b5c1afcdaa7. (CVE-2024-1085)

  - 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)

  - A race condition was found in the Linux kernel's bluetooth device driver in {min,max}_key_size_set()
    function. This can result in a null pointer dereference issue, possibly leading to a kernel panic or
    denial of service issue. (CVE-2024-24860)
