    An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

    nftables out-of-bounds read in nf_osf_match_one() (CVE-2023-39189)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the     fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds     read by setting the size fields with a value beyond the array boundaries, leading to a crash or     information disclosure. (CVE-2023-39192)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the     flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds     read, leading to a crash or information disclosure. (CVE-2023-39193)

    An integer overflow in kmalloc_reserve() in the Linux kernel may allow a local user to crash the system,     or in some cases obtain code execution in kernel space. (CVE-2023-42752)

    The upstream commit describes this issue as follows:

    The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can lead to the use of wrong     `CIDR_POS(c)` for calculating array offsets, which can lead to integer underflow. As a result, it leads to     slab out-of-bound access. (CVE-2023-42753)

    A flaw was found in rsvp_change(). The root cause is an slab-out-of-bound access, but since the offset to     the original pointer is an `unsign int` fully controlled by users, the behavior is usually a wild pointer     access. (CVE-2023-42755)

    An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel     before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)

    A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control)     component can be exploited to achieve local privilege escalation.

    If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing     curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in     update_vf(). This leaves a dangling pointer that can cause a use-after-free.

    We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f. (CVE-2023-4623)

    Rejected reason: CVE-2023-4881 was wrongly assigned to a bug that was deemed to be a non-security issue by     the Linux kernel security team. (CVE-2023-4881)

    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, the following vulnerability has been resolved:

    netfilter: nftables: exthdr: fix 4-byte stack OOB write

    If priv->len is a multiple of 4, then dst[len / 4] can write pastthe destination array which leads to     stack corruption.

    This construct is necessary to clean the remainder of the registerin case ->len is NOT a multiple of the     register size, so make itconditional just like nft_payload.c does.

    The bug was added in 4.1 cycle and then copied/inherited whentcp/sctp and ip option support was added.

    Bug reported by Zero Day Initiative project (ZDI-CAN-21950,ZDI-CAN-21951, ZDI-CAN-21961). (CVE-2023-52628)

    A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm     scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific     socket configuration, which could allow a local user to crash the system or escalate their privileges on     the system. (CVE-2023-6176)

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - Information exposure through microarchitectural state after transient execution in certain vector     execution units for some Intel(R) Processors may allow an authenticated user to potentially enable     information disclosure via local access. (CVE-2022-40982)

  - 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/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 use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited     to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate     filters in case of a perfect hashes while deleting the underlying structure which can later lead to double     freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.
    We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. (CVE-2023-1829)

  - A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address     prediction. This may result in speculative execution at an attacker-controlled address, potentially     leading to information disclosure. (CVE-2023-20569)

  - A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss     of confidentiality. (CVE-2023-20588)

  - In multiple functions of io_uring.c, there is a possible kernel memory corruption due to improper locking.
    This could lead to local escalation of privilege in the kernel with System execution privileges needed.
    User interaction is not needed for exploitation. (CVE-2023-21400)

  - An issue was discovered in drivers/mtd/ubi/cdev.c in the Linux kernel 6.2. There is a divide-by-zero error     in do_div(sz,mtd->erasesize), used indirectly by ctrl_cdev_ioctl, when mtd->erasesize is 0.
    (CVE-2023-31085)

  - An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked     whether the chain is bound and the chain's owner rule can also release the objects in certain     circumstances. We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8.
    (CVE-2023-3777)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did     not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN)     attacker to trigger an out-of-bounds read, leading to a crash or information disclosure. (CVE-2023-39189)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the     fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds     read by setting the size fields with a value beyond the array boundaries, leading to a crash or     information disclosure. (CVE-2023-39192)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the     flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds     read, leading to a crash or information disclosure. (CVE-2023-39193)

  - A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing     of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local     privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an     information disclosure. (CVE-2023-39194)

  - A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function     dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one     holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a     use-after-free issue, potentially leading to a denial of service or privilege escalation. (CVE-2023-39198)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. On an error when building a nftables rule, deactivating immediate     expressions in nft_immediate_deactivate() can lead unbinding the chain and objects be deactivated but     later used. We recommend upgrading past commit 0a771f7b266b02d262900c75f1e175c7fe76fec2. (CVE-2023-4015)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Due to a race condition between nf_tables netlink control plane     transaction and nft_set element garbage collection, it is possible to underflow the reference counter     causing a use-after-free vulnerability. We recommend upgrading past commit     3e91b0ebd994635df2346353322ac51ce84ce6d8. (CVE-2023-4244)

  - An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro     could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to     arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash     the system or potentially escalate their privileges on the system. (CVE-2023-42753)

  - A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was     assumed to be associated with a device before calling __ip_options_compile, which is not always the case     if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash     the system. (CVE-2023-42754)

  - A flaw was found in the Netfilter subsystem of the Linux kernel. A race condition between IPSET_CMD_ADD     and IPSET_CMD_SWAP can lead to a kernel panic due to the invocation of `__ip_set_put` on a wrong `set`.
    This issue may allow a local user to crash the system. (CVE-2023-42756)

  - An issue was discovered in drivers/usb/storage/ene_ub6250.c for the ENE UB6250 reader driver in the Linux     kernel before 6.2.5. An object could potentially extend beyond the end of an allocation. (CVE-2023-45862)

  - An issue was discovered in lib/kobject.c in the Linux kernel before 6.2.3. With root access, an attacker     can trigger a race condition that results in a fill_kobj_path out-of-bounds write. (CVE-2023-45863)

  - An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel     before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)

  - A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local     privilege escalation. The unix_stream_sendpage() function tries to add data to the last skb in the peer's     recv queue without locking the queue. Thus there is a race where unix_stream_sendpage() could access an     skb locklessly that is being released by garbage collection, resulting in use-after-free. We recommend     upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c. (CVE-2023-4622)

  - A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control)     component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve     (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call     vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling     pointer that can cause a use-after-free. We recommend upgrading past commit     b3d26c5702c7d6c45456326e56d2ccf3f103e60f. (CVE-2023-4623)

  - An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access     to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES     emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege     escalation). This depends on a race condition through which userspace can replace an instruction before     the #VC handler reads it. (CVE-2023-46813)

  - An issue was discovered in the Linux kernel through 6.5.9. During a race with SQ thread exit, an     io_uring/fdinfo.c io_uring_show_fdinfo NULL pointer dereference can occur. (CVE-2023-46862)

  - 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)

  - A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a     logical bug in the NVMe/TCP subsystem in the Linux kernel. This issue may allow a malicious user to cause     a use-after-free and double-free problem, which may permit remote code execution or lead to local     privilege escalation. (CVE-2023-5178)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Addition and removal of rules from chain bindings within the same     transaction causes leads to use-after-free. We recommend upgrading past commit     f15f29fd4779be8a418b66e9d52979bb6d6c2325. (CVE-2023-5197)

  - 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 null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm     scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific     socket configuration, which could allow a local user to crash the system or escalate their privileges on     the system. (CVE-2023-6176)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

    nftables out-of-bounds read in nf_osf_match_one() (CVE-2023-39189)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the     fields in the xt_u32 structure. This flaw allows a local privileged attacker to trigger an out-of-bounds     read by setting the size fields with a value beyond the array boundaries, leading to a crash or     information disclosure. (CVE-2023-39192)

    A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the     flag_count field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds     read, leading to a crash or information disclosure. (CVE-2023-39193)

    The upstream commit describes this issue as follows:

    The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can lead to the use of wrong     `CIDR_POS(c)` for calculating array offsets, which can lead to integer underflow. As a result, it leads to     slab out-of-bound access. (CVE-2023-42753)

    An issue was discovered in drivers/net/ethernet/intel/igb/igb_main.c in the IGB driver in the Linux kernel     before 6.5.3. A buffer size may not be adequate for frames larger than the MTU. (CVE-2023-45871)

    A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control)     component can be exploited to achieve local privilege escalation.

    If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing     curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in     update_vf(). This leaves a dangling pointer that can cause a use-after-free.

    We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f. (CVE-2023-4623)

    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)

    A use-after-free vulnerability was found in drivers/nvme/target/tcp.c` in `nvmet_tcp_free_crypto` due to a     logical bug in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a malicious user to     cause a use-after-free and double-free problem, which may permit remote code execution or lead to local     privilege escalation in case that the attacker already has local privileges. (CVE-2023-5178)

    A null pointer dereference flaw was found in the Linux kernel API for the cryptographic algorithm     scatterwalk functionality. This issue occurs when a user constructs a malicious packet with specific     socket configuration, which could allow a local user to crash the system or escalate their privileges on     the system. (CVE-2023-6176)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Information exposure through microarchitectural state after transient execution in certain vector     execution units for some Intel(R) Processors may allow an authenticated user to potentially enable     information disclosure via local access. (CVE-2022-40982)

  - 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/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 division-by-zero error on some AMD processors can potentially return speculative data resulting in loss     of confidentiality. (CVE-2023-20588)

  - In multiple functions of io_uring.c, there is a possible kernel memory corruption due to improper locking.
    This could lead to local escalation of privilege in the kernel with System execution privileges needed.
    User interaction is not needed for exploitation. (CVE-2023-21400)

  - An issue was discovered in the USB subsystem in the Linux kernel through 6.4.2. There is an out-of-bounds     and crash in read_descriptors in drivers/usb/core/sysfs.c. (CVE-2023-37453)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. When nf_tables_delrule() is flushing table rules, it is not checked     whether the chain is bound and the chain's owner rule can also release the objects in certain     circumstances. We recommend upgrading past commit 6eaf41e87a223ae6f8e7a28d6e78384ad7e407f8.
    (CVE-2023-3777)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did     not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN)     attacker to trigger an out-of-bounds read, leading to a crash or information disclosure. (CVE-2023-39189)

  - A flaw was found in the Netfilter subsystem in the Linux kernel. The xt_u32 module did not validate the     fields in the xt_u32 structure.

  - A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing     of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local     privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, potentially leading to an     information disclosure. (CVE-2023-39194)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. On an error when building a nftables rule, deactivating immediate     expressions in nft_immediate_deactivate() can lead unbinding the chain and objects be deactivated but     later used. We recommend upgrading past commit 0a771f7b266b02d262900c75f1e175c7fe76fec2. (CVE-2023-4015)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Due to a race condition between nf_tables netlink control plane     transaction and nft_set element garbage collection, it is possible to underflow the reference counter     causing a use-after-free vulnerability. We recommend upgrading past commit     3e91b0ebd994635df2346353322ac51ce84ce6d8. (CVE-2023-4244)

  - An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro     could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to     arbitrarily increment/decrement a memory buffer out-of-bound. This issue may allow a local user to crash     the system or potentially escalate their privileges on the system. (CVE-2023-42753)
