Name of the Vulnerable Software and Affected Versions: ImageMagick versions 6.x through 6.9.10-41 ImageMagick versions 7.x through 7.0.8-41 Description: The issue is related to a use after free vulnerability in the UnmapBlob function. This vulnerability allows an attacker to cause a denial of...

kernel: memory leak when merging buffers in SCSI IO vectors

It was found that in the Linux kernel through v4.14-rc5, biomapuseriov and biounmapuser in 'block/bio.c' do unbalanced pages refcounting if IO vector has small consecutive buffers belonging to the same page. bioaddpcpage merges them into one, but the page reference is never dropped, causing a...

kernel: Use-after-free in the vmacache_flush_all function resulting in a possible privilege escalation

A security flaw was discovered in the Linux kernel. The vmacacheflushall function in mm/vmacache.c mishandles sequence number overflows. An attacker can trigger a use-after-free and possibly gain privileges via certain thread creation, map, unmap, invalidation, and dereference operations...

kernel: memory leak when merging buffers in SCSI IO vectors

It was found that in the Linux kernel through v4.14-rc5, biomapuseriov and biounmapuser in 'block/bio.c' do unbalanced pages refcounting if IO vector has small consecutive buffers belonging to the same page. bioaddpcpage merges them into one, but the page reference is never dropped, causing a...

Null pointer dereference

The Linux Kernel versions 4.14, 4.15, and 4.16 has a null pointer dereference which can result in an out of memory OOM killing of large mlocked processes. The issue arises from an oom killed process's final thread calling exitmmap, which calls munlockvmapagesall for mlocked vmas.This can happen...
