The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:0514-1 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)

  - A use-after-free vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to     achieve local privilege escalation. When the plug qdisc is used as a class of the qfq qdisc, sending     network packets triggers use-after-free in qfq_dequeue() due to the incorrect .peek handler of sch_plug     and lack of error checking in agg_dequeue(). We recommend upgrading past commit     8fc134fee27f2263988ae38920bc03da416b03d8. (CVE-2023-4921)

  - 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 use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's     deletion of SKB races with unix_stream_read_generic() on the socket that the SKB is queued on.
    (CVE-2023-6531)

  - 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)

    It was discovered that the Siano USB MDTV receiver device driver in the Linux kernel did not properly     handle device initialization failures in certain situations, leading to a use-after-free vulnerability. A     physically proximate attacker could use this cause a denial of service (system crash). (CVE-2023-4132)

    Pratyush Yadav discovered that the Xen network backend implementation in the Linux kernel did not properly     handle zero length data request, leading to a null pointer dereference vulnerability. An attacker in a     guest VM could possibly use this to cause a denial of service (host domain crash). (CVE-2023-46838)

    It was discovered that a race condition existed in the AppleTalk networking subsystem of the Linux kernel,     leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service     (system crash) or possibly execute arbitrary code. (CVE-2023-51781)

    Alon Zahavi discovered that the NVMe-oF/TCP subsystem of the Linux kernel did not properly handle connect     command payloads in certain situations, leading to an out-of-bounds read vulnerability. A remote attacker     could use this to expose sensitive information (kernel memory). (CVE-2023-6121)

    It was discovered that the ext4 file system implementation in the Linux kernel did not properly handle the     remount operation in certain cases, leading to a use-after-free vulnerability. A local attacker could use     this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2024-0775)

    Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict     parameters in certain cases, leading to a use- after-free vulnerability. A local attacker could use this     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2024-1086)

    It was discovered that a race condition existed in the SCSI Emulex LightPulse Fibre Channel driver in the     Linux kernel when unregistering FCF and re-scanning an HBA FCF table, leading to a null pointer     dereference vulnerability.

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 SLES15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1493-1 advisory.

  - A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf)     component can be exploited to achieve local privilege escalation. If perf_read_group() is called while an     event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory     locations outside of the allocated buffer. We recommend upgrading past commit     32671e3799ca2e4590773fd0e63aaa4229e50c06. (CVE-2023-5717)

  - 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)

  - In the Linux kernel, the following vulnerability has been resolved: tomoyo: fix UAF write bug in     tomoyo_write_control() Since tomoyo_write_control() updates head->write_buf when write() of long lines is     requested, we need to fetch head->write_buf after head->io_sem is held. Otherwise, concurrent write()     requests can cause use-after-free-write and double-free problems. (CVE-2024-26622)
