Linux kernel do_mremap allows elevated privileges

linux-mremap-gain-privileges (15244) The risk level is classified as HighHigh Risk

Description:

Linux kernel could allow a local attacker to gain elevated privileges on the system, caused by a vulnerability in the memory management code. The do_mremap function allows for the remapping, resizing, and moving of a virtual memory area (VMA). The do_mremap function fails to properly check the value returned by the do_munmap function. A local attacker could exploit this vulnerability to execute arbitrary code on the vulnerable system with elevated privileges.


Consequences:

Gain Privileges
