kernel: heap buffer overflow in the iSCSI subsystem

A flaw was found in the Linux kernel. A heap buffer overflow in the iSCSI subsystem is triggered by setting an iSCSI string attribute to a value larger than one page and then trying to read it. The highest threat from this vulnerability is to data confidentiality and integrity as well as system...

CVE-2021-3491

The iouring subsystem in the Linux kernel allowed the MAXRWCOUNT limit to be bypassed in the PROVIDEBUFFERS operation, which led to negative values being usedin memrw when reading /proc//mem. This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was...
