K36462841: Linux kernel vulnerability CVE-2018-18281
Security Advisory Description Since Linux kernel version 3.2, the mremap syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate removes entries from the pagetables of a task that is in the middle of mremap, a stale TLB entry can remain for a short time that...
kernel: mm/mremap.c use-after-free vulnerability
A use-after-free flaw was found in the Linux kernel’s mm/mremap memory address space accounting source code in how a race condition happens between rmap walk and mremap. This flaw allows a local user to crash or potentially escalate their privileges on the system...

SUSE CVE-2003-0985
The mremap system call domremap in Linux kernel 2.4.x before 2.4.21, and possibly other versions before 2.4.24, does not properly perform bounds checks, which allows local users to cause a denial of service and possibly gain privileges by causing a remapping of a virtual memory area VMA to create...
SUSE CVE-2004-0077
The domremap function for the mremap system call in Linux 2.2 to 2.2.25, 2.4 to 2.4.24, and 2.6 to 2.6.2, does not properly check the return value from the domunmap function when the maximum number of VMA descriptors is exceeded, which allows local users to gain root privileges, a different...
SUSE CVE-2010-0291
The Linux kernel before 2.6.32.4 allows local users to gain privileges or cause a denial of service panic by calling the 1 mmap or 2 mremap function, aka the "domremap mess" or "mremap/mmap mess."...
SUSE CVE-2011-2496
Integer overflow in the vmatoresize function in mm/mremap.c in the Linux kernel before 2.6.39 allows local users to cause a denial of service BUGON and system crash via a crafted mremap system call that expands a memory mapping...
