An update of the linux package has been released.

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4030-1 advisory.

  - 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)

  - 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)

  - cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial     of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes     indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

  - An issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before     6.4.10. There is a use-after-free because the children of an sk are mishandled. (CVE-2023-40283)

  - 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 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)

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-2023:4347-1 advisory.

  - 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)

  - A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS     transfers response data to a system call, there are still local variable points to the memory region, and     if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a     denial of service. (CVE-2023-1192)

  - 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)

  - 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)

  - The vulnerability exists due to improper event handling in Linux kernel. A malicious guest can disable     paravirtualized device to cause a deadlock in a backend domain (other than dom0). (CVE-2023-34324)

  - 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)

  - An issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before     6.4.10. There is a use-after-free because the children of an sk are mishandled. (CVE-2023-40283)

  - 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)

  - 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)

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    CVE-2021-44879

        Wenqing Liu reported a NULL pointer dereference in the f2fs         implementation. An attacker able to mount a specially crafted image         can take advantage of this flaw for denial of service.

    CVE-2023-0590

        Dmitry Vyukov discovered a race condition in the network scheduler         core that that can lead to a use-after-free.  A local user with         the CAP_NET_ADMIN capability in any user or network namespace         could exploit this to cause a denial of service (crash or memory         corruption) or possibly for privilege escalation.

    CVE-2023-1077

        Pietro Borrello reported a type confusion flaw in the task         scheduler.  A local user might be able to exploit this to cause a         denial of service (crash or memory corruption) or possibly for         privilege escalation.

    CVE-2023-1206

        It was discovered that the networking stack permits attackers to         force hash collisions in the IPv6 connection lookup table, which         may result in denial of service (significant increase in the cost         of lookups, increased CPU utilization).

    CVE-2023-1989

        Zheng Wang reported a race condition in the btsdio Bluetooth         adapter driver that can lead to a use-after-free.  An attacker         able to insert and remove SDIO devices can use this to cause a         denial of service (crash or memory corruption) or possibly to run         arbitrary code in the kernel.

    CVE-2023-3212

        Yang Lan discovered that missing validation in the GFS2 filesystem         could result in denial of service via a NULL pointer dereference         when mounting a malformed GFS2 filesystem.

        Budimir Markovic reported a missing configuration check in the         sch_hfsc network scheduler that could lead to a use-after-free or         other problems.  A local user with the CAP_NET_ADMIN capability in         any user or network namespace could exploit this to cause a denial         of service (crash or memory corruption) or possibly for privilege         escalation.

    CVE-2023-4921

        valis reported flaws in the sch_qfq network scheduler that could         lead to a use-after-free.  A local user with the CAP_NET_ADMIN         capability in any user or network namespace could exploit this to         cause a denial of service (crash or memory corruption) or possibly         for privilege escalation.

    CVE-2023-5717

        Budimir Markovic reported a heap out-of-bounds write vulnerability         in the Linux kernel's Performance Events system caused by improper         handling of event groups, which may result in denial of service or         privilege escalation. The default settings in Debian prevent         exploitation unless more permissive settings have been applied in         the kernel.perf_event_paranoid sysctl.

    CVE-2023-6606

        j51569436 reported a potential out-of-bounds read in the CIFS         filesystem implementation.  If a CIFS filesystem is mounted from a         malicious server, the server could possibly exploit this to cause         a denial of service (crash).

    CVE-2023-6931

        Budimir Markovic reported a heap out-of-bounds write vulnerability         in the Linux kernel's Performance Events system which may result in         denial of service or privilege escalation.

    CVE-2023-39189, CVE-2023-39192, CVE-2023-39193

        Lucas Leong of Trend Micro Zero Day Initiative reported missing         bounds checks in the nfnetlink_osf, xt_u32, and xt_sctp netfilter         modules.  A local user with the CAP_NET_ADMIN capability in any         user or network namespace could exploit these to leak sensitive         information from the kernel or for denial of service (crash).

    CVE-2023-39194

        Lucas Leong of Trend Micro Zero Day Initiative reported a missing         bounds check in the xfrm (IPsec) subsystem.  A local user with the         CAP_NET_ADMIN capability in any user or network namespace could         exploit this to leak sensitive information from the kernel or for         denial of service (crash).

    CVE-2023-40283

        A use-after-free was discovered in Bluetooth L2CAP socket         handling.

    CVE-2023-42753

        Kyle Zeng discovered an off-by-one error in the netfilter ipset         subsystem which could lead to out-of-bounds memory access.  A         local user with the CAP_NET_ADMIN capability in any user or         network namespace could exploit this to cause a denial of service         (memory corruption or crash) and possibly for privilege         escalation.

    CVE-2023-42754

        Kyle Zeng discovered a flaw in the IPv4 implementation which could         lead to a null pointer deference.  A local user could exploit this         for denial of service (crash).

    CVE-2023-42755

        Kyle Zeng discovered missing configuration validation in the         cls_rsvp network classifier which could lead to out-of-bounds         reads.  A local user with the CAP_NET_ADMIN capability in any user         or network namespace could exploit this to cause a denial of         service (crash) or to leak sensitive information.

        This flaw has been mitigated by removing the cls_rsvp classifier.

    CVE-2023-45863

        A race condition in library routines for handling generic kernel         objects may result in an out-of-bounds write in the         fill_kobj_path() function.

    CVE-2023-45871

        Manfred Rudigier reported a flaw in the igb network driver for         Intel Gigabit Ethernet interfaces.  When the rx-all feature was         enabled on such a network interface, an attacker on the same         network segment could send packets that would overflow a receive         buffer, leading to a denial of service (crash or memory         corruption) or possibly remote code execution.

    CVE-2023-51782
