CVE-2019-10140 – kernel: overlayfs: NULL pointer dereference in ovl_posix_acl_create function in fs/overlayfs/dir.c
https://notcve.org/view.php?id=CVE-2019-10140
A vulnerability was found in Linux kernel's, versions up to 3.10, implementation of overlayfs. An attacker with local access can create a denial of service situation via NULL pointer dereference in ovl_posix_acl_create function in fs/overlayfs/dir.c. This can allow attackers with ability to create directories on overlayfs to crash the kernel creating a denial of service (DOS). Se encontró una vulnerabilidad en la implementación de overlayfs, versiones hasta 3.10, del kernel de Linux. Un atacante con acceso local puede crear una situación de denegación de servicio por medio de una desreferencia del puntero NULL en la función ovl_posix_acl_create en el archivo fs/overlayfs/dir.c. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-10140 https://security.netapp.com/advisory/ntap-20190905-0002 https://access.redhat.com/security/cve/CVE-2019-10140 https://bugzilla.redhat.com/show_bug.cgi?id=1677778 • CWE-476: NULL Pointer Dereference •
CVE-2017-18509
https://notcve.org/view.php?id=CVE-2017-18509
An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187. • http://packetstormsecurity.com/files/154059/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=99253eb750fda6a644d5188fb26c43bad8d5a745 https://github.com/torvalds/linux/commit/99253eb750fda6a644d5188fb26c43bad8d5a745 https://lists.debian.org/debian-lts-announce/2019/08/msg00016.html https://lists.debian.org/debian-lts-announce/2019/08/msg00017.html https://lists.openwall.net/netdev/2017/12/04/40 https://pulsesecurity.co.nz/ad • CWE-20: Improper Input Validation •
CVE-2019-10207 – kernel: null-pointer dereference in hci_uart_set_flow_control
https://notcve.org/view.php?id=CVE-2019-10207
A flaw was found in the Linux kernel's Bluetooth implementation of UART, all versions kernel 3.x.x before 4.18.0 and kernel 5.x.x. An attacker with local access and write permissions to the Bluetooth hardware could use this flaw to issue a specially crafted ioctl function call and cause the system to crash. Se encontró un fallo en la implementación Bluetooth del kernel de Linux de UART, todas las versiones del kernel 3.x.x anteriores a 4.18.0 y kernel 5.x.x. Un atacante con acceso local y permisos de escritura en el hardware de Bluetooth podría usar este fallo para emitir una llamada de función ioctl especialmente diseñada y causar que el sistema se bloquee.

CVE-2018-16871 – kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence
https://notcve.org/view.php?id=CVE-2018-16871
A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost. Se detectó un fallo en la implementación de NFS del kernel de Linux, todas las versiones 3.x y todas las versiones 4.x hasta 4.20. • https://access.redhat.com/errata/RHSA-2019:2696 https://access.redhat.com/errata/RHSA-2019:2730 https://access.redhat.com/errata/RHSA-2020:0740 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16871 https://security.netapp.com/advisory/ntap-20211004-0002 https://support.f5.com/csp/article/K18657134 https://support.f5.com/csp/article/K18657134?utm_source=f5support&%3Butm_medium=RSS https://access.redhat.com/security/cve/CVE-2018-16871 https://bugzilla.redhat.com/show_b • CWE-476: NULL Pointer Dereference •
