CVE-2018-5332 – kernel: rds_message_alloc_sgs() function doesn't validate value used during DMA page allocation causes heap out-of-bounds write
https://notcve.org/view.php?id=CVE-2018-5332
In the Linux kernel through 3.2, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size function in net/rds/rdma.c). En el kernel de Linux hasta la versión 3.2, la función rds_message_alloc_sgs() no valida un valor empleado durante la asignación de página DMA, lo que conduce a una escritura fuera de límites basada en memoria dinámica (heap), relacionado con la función rds_rdma_extra_size en net/rds/rdma.c In the Linux kernel through 4.14.13, the rds_message_alloc_sgs() function does not validate a value that is used during DMA page allocation, leading to a heap-based out-of-bounds write (related to the rds_rdma_extra_size() function in 'net/rds/rdma.c') and thus to a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c095508770aebf1b9218e77026e48345d719b17c http://www.securityfocus.com/bid/102507 https://access.redhat.com/errata/RHSA-2018:0470 https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=60daca9efbb3e4109ebc1f7069543e5573fc124e https://github.com/torvalds/linux/commit/c095508770aebf1b9218e77026e48345d719b17c https://lists.debian.org/debian-lts-announce/2018/05/msg00000.html https://usn.ubuntu.com/3617-1 https://usn. • CWE-787: Out-of-bounds Write •
CVE-2018-1000026 – kernel: Improper validation in bnx2x network card driver can allow for denial of service attacks via crafted packet
https://notcve.org/view.php?id=CVE-2018-1000026
Linux Linux kernel version at least v4.8 onwards, probably well before contains a Insufficient input validation vulnerability in bnx2x network card driver that can result in DoS: Network card firmware assertion takes card off-line. This attack appear to be exploitable via An attacker on a must pass a very large, specially crafted packet to the bnx2x card. This can be done from an untrusted guest VM.. El kernel de Linux, al menos desde la versión v4.8, contiene una vulnerabilidad de validación de entradas insuficiente en el controlador de la tarjeta de red bnx2x que puede resultar en un DoS: la aserción del firmware de la tarjeta de red toma la tarjeta offline. Parece que el ataque puede ser explotado mediante un atacante que deba pasar un paquete muy grande, especialmente manipulado a la tarjeta bnx2x. • http://lists.openwall.net/netdev/2018/01/16/40 http://lists.openwall.net/netdev/2018/01/18/96 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://lists.debian.org/debian-lts-announce/2019/05/msg00002.html https://patchwork.ozlabs.org/patch/859410 https://usn.ubuntu.com/3617-1 https://usn.ubuntu.com/3617-2 https://usn.ubuntu.com/3617-3 https://usn. • CWE-20: Improper Input Validation •
