CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2018-7757 – kernel: Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c
https://notcve.org/view.php?id=CVE-2018-7757
Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c in the Linux kernel through 4.15.7 allows local users to cause a denial of service (memory consumption) via many read accesses to files in the /sys/class/sas_phy directory, as demonstrated by the /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file. Filtrado de memoria en la función sas_smp_get_phy_events en drivers/scsi/libsas/sas_expander.c en el kernel de Linux, hasta la versión 4.15.7, permite que usuarios locales provoquen una denegación de servicio (consumo de memoria) mediante numerosos accesos de lectura a archivos en el directorio /sys/class/sas_phy, tal y como demuestra el archivo /sys/class/sas_phy/phy-1:0:12/invalid_dword_count. Memory leak in the sas_smp_get_phy_events function in drivers/scsi/libsas/sas_expander.c in the Linux kernel allows local users to cause a denial of service (kernel memory exhaustion) via multiple read accesses to files in the /sys/class/sas_phy directory. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4a491b1ab11ca0556d2fda1ff1301e862a2d44c4 http://www.securityfocus.com/bid/103348 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3096 https://github.com/torvalds/linux/commit/4a491b1ab11ca0556d2fda1ff1301e862a2d44c4 https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https://usn.ubuntu.com/3654-1 https://usn.ubuntu. • CWE-400: Uncontrolled Resource Consumption CWE-772: Missing Release of Resource after Effective Lifetime •

https://notcve.org/view.php?id=CVE-2018-7755
An issue was discovered in the fd_locked_ioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR. Se descubrió un fallo de seguridad en la función fd_locked_ioct en drivers/block/floppy.c en el kernel de Linux hasta la versión 4.15.7. La unidad de disquete copiará un puntero kernel a la memoria del usuario en respuesta a la llamada IOCTL FDGETPRM. • https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://lists.debian.org/debian-lts-announce/2018/10/msg00003.html https://lkml.org/lkml/2018/3/7/1116 https://usn.ubuntu.com/3695-1 https://usn.ubuntu.com/3695-2 https://usn.ubuntu.com/3696-1 https://usn.ubuntu.com/3696-2 https://usn.ubuntu.com/3697-1 https://usn.ubuntu.com/3697-2 https://usn.ubuntu.com/3698-1 https://usn.ubuntu.com/369 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
