high Nessus Plugin ID 168948

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:4585-1 advisory.

- A flaw was found in hw. Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-23816) (CVE-2022-2602)

- There exists a use-after-free in io_uring in the Linux kernel. Signalfd_poll() and binder_poll() use a waitqueue whose lifetime is the current task. It will send a POLLFREE notification to all waiters before the queue is freed. Unfortunately, the io_uring poll doesn't handle POLLFREE. This allows a use-after-free to occur if a signalfd or binder fd is polled with io_uring poll, and the waitqueue gets freed. We recommend upgrading past commit fc78b2fc21f10c4c9c4d5d659a685710ffa63659 (CVE-2022-3176)

- A vulnerability, which was classified as problematic, was found in Linux Kernel. This affects the function tcp_getsockopt/tcp_setsockopt of the component TCP Handler. The manipulation leads to race condition. It is recommended to apply a patch to fix this issue. The identifier VDB-211089 was assigned to this vulnerability. (CVE-2022-3566)

- A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects the function inet6_stream_ops/inet6_dgram_ops of the component IPv6 Handler. The manipulation leads to race condition. It is recommended to apply a patch to fix this issue. VDB-211090 is the identifier assigned to this vulnerability. (CVE-2022-3567)

- A vulnerability, which was classified as critical, has been found in Linux Kernel. Affected by this issue is the function tst_timer of the file drivers/atm/idt77252.c of the component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. VDB-211934 is the identifier assigned to this vulnerability. (CVE-2022-3635)

- Guests can trigger NIC interface reset/abort/crash via netback It is possible for a guest to trigger a NIC interface reset/abort/crash in a Linux based network backend by sending certain kinds of packets. It appears to be an (unwritten?) assumption in the rest of the Linux network stack that packet protocol headers are all contained within the linear section of the SKB and some NICs behave badly if this is not the case. This has been reported to occur with Cisco (enic) and Broadcom NetXtrem II BCM5780 (bnx2x) though it may be an issue with other NICs/drivers as well. In case the frontend is sending requests with split headers, netback will forward those violating above mentioned assumption to the networking core, resulting in said misbehavior. (CVE-2022-3643)

- A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card system resource overload, causing a fail in the intel_gvt_dma_map_guest_page function. This issue could allow a local user to crash the system. (CVE-2022-3707)

- An incorrect read request flaw was found in the Infrared Transceiver USB driver in the Linux kernel. This issue occurs when a user attaches a malicious USB device. A local user could use this flaw to starve the resources, causing denial of service or potentially crashing the system. (CVE-2022-3903)

- A use-after-free flaw was found in Linux kernel before 5.19.2. This issue occurs in cmd_hdl_filter in drivers/staging/rtl8712/rtl8712_cmd.c, allowing an attacker to launch a local denial of service attack and gain escalation of privileges. (CVE-2022-4095)

- A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service. (CVE-2022-4129)

- An incorrect TLB flush issue was found in the Linux kernel's GPU i915 kernel driver, potentially leading to random memory corruption or data leaks. This flaw could allow a local user to crash the system or escalate their privileges on the system. (CVE-2022-4139)

- roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free in certain situations where a report is received while copying a report->value is in progress. (CVE-2022-41850)

- A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to crash the system or leak internal kernel information. (CVE-2022-41858)

- Guests can trigger deadlock in Linux netback driver T[his CNA information record relates to multiple CVEs;
the text explains which aspects/vulnerabilities correspond to which CVE.] The patch for XSA-392 introduced another issue which might result in a deadlock when trying to free the SKB of a packet dropped due to the XSA-392 handling (CVE-2022-42328). Additionally when dropping packages for other reasons the same deadlock could occur in case of netpoll being active for the interface the xen-netback driver is connected to (CVE-2022-42329). (CVE-2022-42328, CVE-2022-42329)

- There is an infoleak vulnerability in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_parse_conf_req function which can be used to leak kernel pointers remotely. We recommend upgrading past commit https://github.com/torvalds/linux/commit/b1a2cd50c0357f243b7435a732b4e62ba3157a2e https://www.google.com/url (CVE-2022-42895)

- There are use-after-free vulnerabilities in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_connect and l2cap_le_connect_req functions which may allow code execution and leaking kernel memory (respectively) remotely via Bluetooth. A remote attacker could execute code leaking kernel memory via Bluetooth if within proximity of the victim. We recommend upgrading past commit https://www.google.com/url https://github.com/torvalds/linux/commit/711f8c3fb3db61897080468586b970c87c61d9e4 https://www.google.com/url (CVE-2022-42896)

- A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-4378)

- The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC message with garbage data is still correctly formed according to the specification and is passed forward to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the allocated buffer space. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H (CVE-2022-43945)

- A race condition in the x86 KVM subsystem in the Linux kernel through 6.1-rc6 allows guest OS users to cause a denial of service (host OS crash or host OS memory corruption) when nested virtualisation and the TDP MMU are enabled. (CVE-2022-45869)

- An issue was discovered in the Linux kernel through 6.0.9. drivers/char/xillybus/xillyusb.c has a race condition and use-after-free during physical removal of a USB device. (CVE-2022-45888)

- An issue was discovered in the Linux kernel through 6.0.10. l2cap_config_req in net/bluetooth/l2cap_core.c has an integer wraparound via L2CAP_CONF_REQ packets. (CVE-2022-45934)

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