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

  - An issue was discovered in the Linux kernel before 5.8.6. drivers/media/cec/core/cec-api.c leaks one byte     of kernel memory on specific hardware to unprivileged users, because of directly assigning log_addrs with     a hole in the struct. (CVE-2020-36766)

  - 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/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)

  - An issue in Zen 2 CPUs, under specific microarchitectural circumstances, may allow an attacker to     potentially access sensitive information. (CVE-2023-20593)

  - Improper access control in the Intel(R) Ethernet Controller RDMA driver for linux before version 1.9.30     may allow an unauthenticated user to potentially enable escalation of privilege via network access.
    (CVE-2023-25775)

  - 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 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)

  - 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)

  - 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 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)

  - 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 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)

The version of kernel installed on the remote host is prior to 5.15.133-86.144. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2023-027 advisory.

    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)

    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)

    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.
