Linux Distros Unpatched Vulnerability : CVE-2026-89644

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - btrfs: fix extent map leak in NOCOW direct I/O write btrfsdioiomapbegin calls btrfsgetextent, which returns an extent map reference that must be dropped on all...

CVE-2026-89656

A flaw was found in libceph within the Linux kernel. This vulnerability allows a local attacker to craft a malformed CRUSH map, which is used for data placement. By doing so, one data bucket can be made to reuse another bucket's memory workspace, leading to an out-of-bounds write. This memory...

CVE-2026-89657

A flaw was found in libceph in the Linux kernel. A malicious or compromised authenticated Ceph Object Storage Device OSD peer could send a specially crafted sparse-read reply that lacks proper validation of extent maps. This could cause the client to advance its message-data cursor beyond the...

CVE-2026-50013

Hoverfly is an open source API simulation tool. Prior to version 1.12.8, when Hoverfly is running in Diff mode, the AddDiff function writes to the shared responsesDiff map without any synchronization no mutex. When multiple proxy requests are processed concurrently the normal case for any proxy,...

CVE-2026-50013 Hoverfly: Process Crash via Concurrent Map Write Race Condition in Diff Mode

Hoverfly is an open source API simulation tool. Prior to version 1.12.8, when Hoverfly is running in Diff mode, the AddDiff function writes to the shared responsesDiff map without any synchronization no mutex. When multiple proxy requests are processed concurrently the normal case for any proxy,...

CVE-2026-50013

Hoverfly (an open-source API simulation/proxy tool by SpectoLabs) is affected by an unsynchronized concurrent map write in its Diff mode . Prior to version 1.12.8 , the AddDiff() function writes to the shared responsesDiff map without a mutex. Because Hoverfly processes proxy requests concurrentl...

CVE-2026-89650

A flaw was found in the Linux kernel's Ceph client. A malicious or compromised Ceph monitor, or an on-path attacker, can send a specially crafted Metadata Server MDS map. This map, with an oversized numexporttargets field and a per-MDS info version of 2 or 3, can trigger an out-of-bounds read in...

CVE-2026-89644

A flaw was found in the Linux kernel's btrfs filesystem. When performing direct I/O writes in a NOCOW No Copy-On-Write range, an extent map reference may not be properly released if an error occurs during extent creation. This oversight can lead to an extent map leak, potentially causing memory...

AZL-100667 CVE-2026-89650 affecting package kernel for versions less than 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: ceph: bound numexporttargets array for mds info v2/v3 cephmdsmapdecode in fs/ceph/mdsmap.c reads numexporttargets from each per-mds info record and advances the decode cursor by numexporttargets sizeofu32 without first checking...

CVE-2026-89657
