Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to a NULL pointer deference in the Linux kernel's ACPICA component. This occurs when memory mappings for operation regions overlap page boundaries, triggering warnin...

DEBIAN-CVE-2022-48690

In the Linux kernel, the following vulnerability has been resolved: ice: Fix DMA mappings leak Fix leak, when user changes ring parameters. During reallocation of RX buffers, new DMA mappings are created for those buffers. New buffers with different RX ring count should substitute older ones, but...

kernel: i40e: Fix DMA mappings leak

A DMA mapping leak vulnerability was found in the Intel i40e network driver in the Linux kernel. During reallocation of RX buffers when changing ring parameters via ethtool, DMA mappings are not properly cleaned up before creating new ones. Repeated ring size changes can exhaust DMA resources,...

SUSE CVE-2021-28694

IOMMU page mapping issues on x86 This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE. Both AMD and Intel allow ACPI tables to specify regions of memory which should be left untranslated, which typically means these addresse...

USN-5779-1 linux-azure, linux-azure-5.15, linux-azure-fde vulnerabilities

It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2022-43945 Jann Horn discovered that the...

USN-5757-2 linux-aws-hwe, linux-gcp, linux-hwe, linux-oracle vulnerabilities

Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2022-427...

PT-2022-14680 · Google · Android Kernel

Name of the Vulnerable Software and Affected Versions: Android kernel versions affected versions not specified Description: The issue is related to improper input validation in the mprot unmap function, which could lead to corruption of the memory mapping. This can result in local escalation of...

Huawei HarmonyOS 安全漏洞

Huawei HarmonyOS is an operating system from Huawei China. It provides a full-scenario distributed operating system based on a microkernel. Huawei HarmonyOS suffers from a security vulnerability that stems from a kernel module automatically freeing memory without clearing the mapping relationship...

CVE-2022-36449

An issue was discovered in the Arm Mali GPU Kernel Driver. A non-privileged user can make improper GPU processing operations to gain access to already freed memory, write a limited amount outside of buffer bounds, or to disclose details of memory mappings. This affects Midgard r4p0 through r32p0,...

An issue was discovered in Xen through 4.14.x. Xenstored and guests communicate via a shared memory page using a specific protocol. When a guest violates this protocol, xenstored will drop the connection to that guest. Unfortunately, this is done by just removing the guest from xenstored's intern...

Xenstore: guests can disturb domain cleanup

ISSUE DESCRIPTION Xenstored and guests communicate via a shared memory page using a specific protocol. When a guest violates this protocol, xenstored will drop the connection to that guest. Unfortunately this is done by just removing the guest from xenstored's internal management, resulting in th...
