Discussion

Linux Kernel do_mremap Function VMA Limit Local Privilege Escalation Vulnerability

It has been reported that the Linux kernel may be prone to a local privilege escalation vulnerability due to a improper checks on return values performed in the do_mremap system function. Successful exploitation of this issue may allow a local attacker with limited privileges on a host to fully compromise the system because special privileges are not required to use the mremap(2) system call. The issue may also allow a denial of service condition on available system memory.

Exploit / POC

Linux Kernel do_mremap Function VMA Limit Local Privilege Escalation Vulnerability

Working exploit code has been released and is included in the attached "Linux kernel do_mremap VMA limit local privilege escalation vulnerability" advisory.

CORE has developed a working commercial exploit for their IMPACT
product. This exploit is not otherwise publicly available or known
to be circulating in the wild.

The following proof of concept supplied by Christophe Devine may be used to test this issue:
