https://notcve.org/view.php?id=CVE-2018-18397
12 Dec 2018 — The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c. La implementación de userfaultfd en el kernel de Linux en versiones anteriores a la 4.17 gestiona de manera incorrecta para ciertas llamadas ioctl UFFDIO_, tal y como queda demos... • https://packetstorm.news/files/id/150748 • CWE-20: Improper Input Validation CWE-863: Incorrect Authorization •

CVE-2018-14652 – glusterfs: Buffer overflow in "features/locks" translator allows for denial of service
https://notcve.org/view.php?id=CVE-2018-14652
31 Oct 2018 — The Gluster file system through versions 3.12 and 4.1.4 is vulnerable to a buffer overflow in the 'features/index' translator via the code handling the 'GF_XATTR_CLRLK_CMD' xattr in the 'pl_getxattr' function. A remote authenticated attacker could exploit this on a mounted volume to cause a denial of service.

CVE-2018-14659 – glusterfs: Unlimited file creation via "GF_XATTR_IOSTATS_DUMP_KEY" xattr allows for denial of service
https://notcve.org/view.php?id=CVE-2018-14659
31 Oct 2018 — The Gluster file system through versions 4.1.4 and 3.1.2 is vulnerable to a denial of service attack via use of the 'GF_XATTR_IOSTATS_DUMP_KEY' xattr. A remote, authenticated attacker could exploit this by mounting a Gluster volume and repeatedly calling 'setxattr(2)' to trigger a state dump and create an arbitrary number of files in the server's runtime directory.

CVE-2018-18559 – kernel: Use-after-free due to race condition in AF_PACKET implementation
https://notcve.org/view.php?id=CVE-2018-18559
22 Oct 2018 — In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanout_add from setsockopt and bind on an AF_PACKET socket. This issue exists because of the 15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a certain multithreaded case involving a packet_do_bind unregister action followed by a packet_notifier register action. Later, packet_release operates on only one of the two applicable linked lists. The attacker can achieve Pro... • https://access.redhat.com/errata/RHBA-2019:0327 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

CVE-2018-17958 – QEMU: rtl8139: integer overflow leads to buffer overflow
