CVE-2019-20054: NULL Pointer Dereference
In the Linux kernel before 5.0.6, there is a NULL pointer dereference in dropsysctltable in fs/proc/procsysctl.c, related to putlinks, aka CID-23da9588037e...
Design/Logic Flaw
In the Linux kernel before 5.4.2, the iouring feature leads to requests that inadvertently have UID 0 and full capabilities, aka CID-181e448d8709. This is related to fs/io-wq.c, fs/iouring.c, and net/socket.c. For example, an attacker can bypass intended restrictions on adding an IPv4 address to...
