Astra Linux – Vulnerability in grub2
An integer overflow flaw was discovered in the BFS file system driver within grub2. When reading a file using an indirect extent map, grub2 fails to validate the number of extent entries to be read. A maliciously crafted or corrupted BFS file system may cause an integer overflow during file...
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-2026-89657
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-2026-89644
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...
