The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4071-1 advisory.

  - A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel's IPv6     functionality when a user makes a new kind of SYN flood attack. A user located in the local network or     with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up     to 95%. (CVE-2023-1206)

  - A use-after-free flaw was found in xen_9pfs_front_removet in net/9p/trans_xen.c in Xen transport for 9pfs     in the Linux Kernel. This flaw could allow a local attacker to crash the system due to a race problem,     possibly leading to a kernel information leak. (CVE-2023-1859)

  - A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in     Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A     local user could use this flaw to crash the system or potentially cause a denial of service.
    (CVE-2023-2177)

  - 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 flaw was found in KVM AMD Secure Encrypted Virtualization (SEV) in the Linux kernel. A KVM guest using     SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke     the `VMGEXIT` handler recursively. If an attacker manages to call the handler multiple times, they can     trigger a stack overflow and cause a denial of service or potentially guest-to-host escape in kernel     configurations without stack guard pages (`CONFIG_VMAP_STACK`). (CVE-2023-4155)

  - 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 btrfs_get_root_ref in fs/btrfs/disk-io.c in the btrfs filesystem in the Linux Kernel     due to a double decrement of the reference count. This issue may allow a local attacker with user     privilege to crash the system or may lead to leaked internal kernel information. (CVE-2023-4389)

  - 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 use-after-free vulnerability in the Linux kernel's fs/smb/client component can be exploited to achieve     local privilege escalation. In case of an error in smb3_fs_context_parse_param, ctx->password was freed     but the field was not set to NULL which could lead to double free. We recommend upgrading past commit     e6e43b8aa7cd3c3af686caf0c2e11819a886d705. (CVE-2023-5345)

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4805-1 advisory.

  - Incorrect verifier pruning in BPF in Linux Kernel >=5.4 leads to unsafe code paths being incorrectly     marked as safe, resulting in arbitrary read/write in kernel memory, lateral privilege escalation, and     container escape. (CVE-2023-2163)

  - A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to     achieve local privilege escalation. Flaw in the error handling of bound chains causes a use-after-free in     the abort path of NFT_MSG_NEWRULE. The vulnerability requires CAP_NET_ADMIN to be triggered. We recommend     upgrading past commit 4bedf9eee016286c835e3d8fa981ddece5338795. (CVE-2023-3610)

  - 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.
