CVE-2018-20855

A flaw was discovered in the Linux kernel's implementation of InfiniBand. A local attacker who is able to execute a read from the InfiniBand device could trigger an information leak of kernel memory to userspace which can be used to further attack the system. Mitigation If the InfiniBand device i...

Linux kernel buffer overflow vulnerability (CNVD-2019-38535)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A buffer overflow vulnerability exists in the writetptentry function in the drivers/infiniband/hw/cxgb4/mem.c file in Linux kernel 5.3.2 and earlier. The vulnerability...

CVE-2019-16921

An information disclosure flaw was found in the Linux kernel. The Infiniband driver does not initialize the resp data structure which allows an attacker to obtain sensitive information from kernel stack memory. The highest threat from this vulnerability is to data confidentiality...
