Vulnerability Title
Libstoragemgmt: libstoragemgmt: denial of service via stack buffer overflow in scsi vpd page parsing
来源: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in libstoragemgmt. An attacker with control over a local or virtual storage device could provide specially crafted SCSI (Small Computer System Interface) Vital Product Data (VPD) page 0x80 data. This malformed data, specifically an untrusted page length field, can lead to a stack buffer overflow in the `_sg_parse_vpd_80()` function during serial number parsing. Successful exploitation could result in a denial of service by crashing or destabilizing the process querying the serial number.
