kernel: mm/vmemmap/devdax: fix kernel crash when probing devdax devices

A flaw was discovered in the device DAX devdax probing implementation of the Linux kernel memory management subsystem mm/vmemmap/devdax. Under specific architecture configurations for example POWER9 with hash MMU, the code path in vmemmappopulatecompoundpages did not properly account for...

SALT - SLUB ALlocator Tracer For The Linux Kernel

Welcome to salt , a tool to reverse and learn kernel heap memory management. It can be useful to develop an exploit, to debug your own kernel code, and, more importantly, to play with the kernel heap allocations and learn its inner workings. This tool helps tracing allocations and the current sta...

Kernel: mm: try_to_unmap_cluster() should lock_page() before mlocking

It was found that the trytounmapcluster function in the Linux kernel's Memory Managment subsystem did not properly handle page locking in certain cases, which could potentially trigger the BUGON macro in the mlockvmapage function. A local, unprivileged user could use this flaw to crash the system...

kernel: mm: keep a guard page below a grow-down stack segment

The doanonymouspage function in mm/memory.c in the Linux kernel before 2.6.27.52, 2.6.32.x before 2.6.32.19, 2.6.34.x before 2.6.34.4, and 2.6.35.x before 2.6.35.2 does not properly separate the stack and the heap, which allows context-dependent attackers to execute arbitrary code by writing to t...
