CVE-2016-10723

An issue was discovered in the Linux kernel through 4.17.2. Since the page allocator does not yield CPU resources to the owner of the oomlock mutex, a local unprivileged user can trivially lock up the system forever by wasting CPU resources from the page allocator e.g., via concurrent page fault...

procps: incorrect integer size in proc/alloc.* leading to truncation / integer overflow issues

A flaw was found where procps-ng provides wrappers for standard C allocators that took unsigned int instead of sizet parameters. On platforms where these differ such as x8664, this could cause integer truncation, leading to undersized regions being returned to callers that could then be overflowe...

Linux - mincore() Uninitialized Kernel Heap Page Disclosure Exploit

Linux mincore discloses uninitialized kernel heap pages. When walkpagerange is used on a VMHUGETLB VMA, callbacks from the mmwalk structure are only invoked for present pages. However, domincore assumes that it will always get callbacks for all pages in the range passed to walkpagerange, and when...

chromium-browser: memory lifecycle issue in pdfium

Inappropriate use of partition alloc in PDFium in Google Chrome prior to 61.0.3163.79 for Linux, Windows, and Mac, and 61.0.3163.81 for Android, allowed a remote attacker to potentially exploit memory corruption via a crafted PDF file...

grant_table: Race conditions with maptrack free list handling

ISSUE DESCRIPTION The grant table code in Xen has a bespoke semi-lockfree allocator for recording grant mappings "maptrack" entries. This allocator has a race which allows the free list to be corrupted. Specifically: the code for removing an entry from the free list, prior to use, assumes without...

UBUNTU-CVE-2017-5546

The freelist-randomization feature in mm/slab.c in the Linux kernel 4.8.x and 4.9.x before 4.9.5 allows local users to cause a denial of service duplicate freelist entries and system crash or possibly have unspecified other impact in opportunistic circumstances by leveraging the selection of a...
