CVE-2013-4299 WRITEUP WRITEUP
Linux Kernel < 3.11.6 - Authenticated Sensitive Information Exposure via Snapshot Block Device Mapping
Interpretation conflict in drivers/md/dm-snap-persistent.c in the Linux kernel through 3.11.6 allows remote authenticated users to obtain sensitive information or modify data via a crafted mapping to a snapshot block device.
CVE-2021-31916 WRITEUP MEDIUM WRITEUP
Linux Kernel < 5.12 - Authenticated Out-of-bounds Write in Multi-device Driver
An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.
CVSS 6.7
CVE-2009-1914 EXPLOITDB text WRITEUP
Linux Kernel < 2.6.29 - Denial of Service via Uninitialized Pointer in pci_register_iommu_region
The pci_register_iommu_region function in arch/sparc/kernel/pci_common.c in the Linux kernel before 2.6.29 on the sparc64 platform allows local users to cause a denial of service (system crash) by reading the /proc/iomem file, related to uninitialized pointers and the request_resource function.
