Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.7.0 Description: The issue is related to a use-after-free problem in the f2fs filemap fault function. This occurs because vmf-vma may not be alive after filemap fault, potentially causing a use-after-free issu...

SUSE CVE-2023-4611

A use-after-free flaw was found in mm/mempolicy.c in the memory management subsystem in the Linux Kernel. This issue is caused by a race between mbind and VMA-locked page fault, and may allow a local attacker to crash the system or lead to a kernel information leak...

kernel: use-after-free related to leaf anon_vma double reuse

A memory leak flaw with use-after-free capability was found in the Linux kernel. The VMA mm/rmap.c functionality in the ismergeableanonvma function continuously forks, using memory operations to trigger an incorrect reuse of leaf anonvma. This issue allows a local attacker to crash the system...

PT-2022-35572 · Xen +1 · Xen/Gntdev +1

Name of the Vulnerable Software and Affected Versions: xen/gntdev versions prior to v5.10.152 Description: The issue is related to VMA splitting in xen/gntdev. It was introduced in version v2.6.38 and fixed in Linux Kernel version v5.10.152. The actual impact and attack plausibility have not yet...

kernel: Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks

A flaw was found in the Linux kernel’s KVM implementation, where improper handing of the VMIO|VMPFNMAP VMAs in KVM bypasses RO checks and leads to pages being freed while still accessible by the VMM and guest. This flaw allows users who can start and control a VM to read/write random pages of...

kernel: fix race condition between mmget_not_zero()/get_task_mm() and core dumping

A flaw was found in the Linux kernel where the coredump implementation does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs. This allows local users to obtain sensitive information, cause a denial of service DoS, or possibly have unspecified other impa...

kernel: mm: avoid wrapping vm_pgoff in mremap() and stack expansions

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...

SuSE-SA:2004:001: Linux Kernel

The remote host is missing the patch for the advisory SuSE-SA:2004:001 Linux Kernel. The domremap function of the Linux Kernel is used to manage move, resize Virtual Memory Areas VMAs. By exploiting an incorrect bounds check in domremap during the remapping of memory it is possible to create a VM...

Linux kernel do_mremap() call creates virtual memory area of 0 bytes in length

Overview There is a vulnerability in the Linux kernel memory management routines that allows local users to gain superuser privileges. Description The Linux kernel contains a vulnerability in the domremap call that allows software to create a virtual memory area VMA with a length of 0 bytes. This...

security flaw

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...
