Medium: pam

Issue Overview: A vulnerability was found in PAM. The secret information is stored in memory, where the attacker can trigger the victim program to execute by sending characters to its standard input stdin. As this occurs, the attacker can train the branch predictor to execute an ROP chain...

kernel: dm ioctl: prevent potential spectre v1 gadget

A vulnerability was found in the Linux kernel's dm-ioctl interface in the lookupioctl function, which accepts a user-provided cmd value that is used to index the ioctls array directly. This issue could lead to an out-of-bounds access if the CPU speculatively executes the array access before cmd i...
