The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1255-1 advisory.

  • Product: AndroidVersions: Android kernelAndroid ID: A-173788806References: Upstream kernel (CVE-2021-39713)

  • In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a corrupted quota file. (CVE-2021-45868)

  • An information leak flaw was found in NFS over RDMA in the net/sunrpc/xprtrdma/rpc_rdma.c in the Linux Kernel. This flaw allows an attacker with normal user privileges to leak kernel information.
    (CVE-2022-0812)

  • A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to userspace. (CVE-2022-0850)

  • A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle ‘return’ with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)

  • A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2022-1048)

  • Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.
    The xenbus driver has a similar problem, as it doesn’t check the success of removing the granted access of a shared ring buffer. blkfront: CVE-2022-23036 netfront: CVE-2022-23037 scsifront: CVE-2022-23038 gntalloc: CVE-2022-23039 xenbus: CVE-2022-23040 blkfront, netfront, scsifront, usbfront, dmabuf, xenbus, 9p, kbdfront, and pvcalls are using a functionality to delay freeing a grant reference until it is no longer in use, but the freeing of the related data page is not synchronized with dropping the granted access. As a result the backend can keep access to the memory page even after it has been freed and then re-used for a different purpose. CVE-2022-23041 netfront will fail a BUG_ON() assertion if it fails to revoke access in the rx path. This will result in a Denial of Service (DoS) situation of the guest which can be triggered by the backend. CVE-2022-23042 (CVE-2022-23036, CVE-2022-23037, CVE-2022-23038, CVE-2022-23039, CVE-2022-23040, CVE-2022-23041, CVE-2022-23042)

  • st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has EVT_TRANSACTION buffer overflows because of untrusted length parameters. (CVE-2022-26490)

  • An issue was discovered in the Linux kernel before 5.16.12. drivers/net/usb/sr9700.c allows attackers to obtain sensitive information from heap memory via crafted frame lengths from a device. (CVE-2022-26966)

  • In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c. (CVE-2022-28356)

  • usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double free. (CVE-2022-28388)

  • mcba_usb_start_xmit in drivers/net/can/usb/mcba_usb.c in the Linux kernel through 5.17.1 has a double free. (CVE-2022-28389)

  • ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c in the Linux kernel through 5.17.1 has a double free.
    (CVE-2022-28390)

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