CVSS: 7.1EPSS: 0%CPEs: 3EXPL: 1CVE-2018-1000004 – kernel: Race condition in sound system can lead to denial of service
https://notcve.org/view.php?id=CVE-2018-1000004
In the Linux kernel 4.12, 3.10, 2.6 and possibly earlier versions a race condition vulnerability exists in the sound system, this can lead to a deadlock and denial of service condition. En el kernel de Linux en versiones 4.12, 3.10, 2.6 y, probablemente, versiones anteriores, existe una vulnerabilidad en el sistema de sonido, lo que puede conducir a un deadlock y a una condición de denegación de servicio (DoS). In the Linux kernel versions 4.12, 3.10, 2.6, and possibly earlier, a race condition vulnerability exists in the sound system allowing for a potential deadlock and memory corruption due to use-after-free condition and thus denial of service. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://seclists.org/oss-sec/2018/q1/51 http://www.securityfocus.com/bid/104606 https://access.redhat.com/errata/RHSA-2018:0654 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2018:2390 https://access.redhat.com/errata/RHSA-2019:1483 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6.0 https://lists.debian.org/debian-lts-announce/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 0CVE-2017-15127 – kernel: Improper error handling of VM_SHARED hugetlbfs mapping in mm/hugetlb.c
https://notcve.org/view.php?id=CVE-2017-15127
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). A flaw was found in the Linux kernel when freeing pages in hugetlbfs. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5af10dfd0afc559bb4b0f7e3e8227a1578333995 http://www.securityfocus.com/bid/102517 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/security/cve/CVE-2017-15127 https://bugzilla.redhat.com/show_bug.cgi?id=1525218 https://github.com/torvalds/linux/commit/5af10dfd0afc559bb4b0f7e3e8227a1578333995 • CWE-460: Improper Cleanup on Thrown Exception •

https://notcve.org/view.php?id=CVE-2017-17975
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. Uso de memoria previamente liberada en la función usbtv_probe en drivers/media/usb/usbtv/usbtv-core.c en el kernel de Linux hasta la versión 4.14.10 permite que atacantes provoquen una denegación de servicio (cierre inesperado del sistema) o, posiblemente, causen otro tipo de impacto sin especificar desencadenando un error de registro de audio. Esto se debe a que un kfree de la estructura de datos usbtv ocurre durante una llamada usbtv_video_free, pero el código de la etiqueta usbtv_video_fail intenta acceder y liberar esta estructura de datos. • http://linuxtesting.org/pipermail/ldv-project/2017-November/001008.html http://www.securityfocus.com/bid/102330 https://usn.ubuntu.com/3653-1 https://usn.ubuntu.com/3653-2 https://usn.ubuntu.com/3654-1 https://usn.ubuntu.com/3654-2 https://usn.ubuntu.com/3656-1 https://usn.ubuntu.com/3657-1 https://www.debian.org/security/2018/dsa-4188 • CWE-416: Use After Free •
