If your production Linux system is logging memory allocation failures, it might still be able to keep running. But developers want to keep an eye on which code can survive a shortage of memory.

Researchers from the Graz University of Technology have discovered a way to convert a limited heap vulnerability in the Linux kernel into a malicious memory writes capability to demonstrate novel ...

uClinux offers a choice of two kernel memory allocators. At first it may not seem obvious why an alternative kernel memory allocator is needed, but in small uClinux systems the difference is painfully ...

A novel Linux Kernel cross-cache attack named SLUBStick has a 99% success in converting a limited heap vulnerability into an arbitrary memory read-and-write capability, letting the researchers ...
