CVE-2017-15127 – kernel: Improper error handling of VM_SHARED hugetlbfs mapping in mm/hugetlb.c
https://notcve.org/view.php?id=CVE-2017-15127
14 Jan 2018 — A flaw was found in the hugetlb_mcopy_atomic_pte function in mm/hugetlb.c in the Linux kernel before 4.13. A superfluous implicit page unlock for VM_SHARED hugetlbfs mapping could trigger a local denial of service (BUG). Se encontró un error en la función hugetlb_mcopy_atomic_pte en mm/hugetlb.c en el kernel de Linux en versiones anteriores a la 4.13. Un desbloqueo superfluo implícito de página para la representación hugetlbfs de VM_SHARED podría desembocar una denegación de servicio local (error).

CVE-2017-15126 – kernel: Use-after-free in userfaultfd_event_wait_completion function in userfaultfd.c
https://notcve.org/view.php?id=CVE-2017-15126
14 Jan 2018 — A use-after-free flaw was found in fs/userfaultfd.c in the Linux kernel before 4.13.6. The issue is related to the handling of fork failure when dealing with event messages. Failure to fork correctly can lead to a situation where a fork event will be removed from an already freed list of events with userfaultfd_ctx_put(). Se ha encontrado un fallo de uso de memoria previamente liberada en fs/userfaultfd.c en el kernel de Linux en versiones anteriores a la 4.13.6.

CVE-2017-18017 – kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c
https://notcve.org/view.php?id=CVE-2017-18017
03 Jan 2018 — The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. La función tcpmss_mangle_packet en net/netfilter/xt_TCPMSS.c en el kernel de Linux, en versiones anteriores a la 4.11 y en versiones 4.9.x anteriores a la 4.9.36, permite que atacantes remotos p... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2638fd0f92d4397884fd991d8f4925cb3f081901 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-416: Use After Free •

30 Dec 2017 — Use-after-free in the usbtv_probe function in drivers/media/usb/usbtv/usbtv-core.c in the Linux kernel through 4.14.10 allows attackers to cause a denial of service (system crash) or possibly have unspecified other impact by triggering failure of audio registration, because a kfree of the usbtv data structure occurs during a usbtv_video_free call, but the usbtv_video_fail label's code attempts to both access and free this data structure.
