Name of the Vulnerable Software and Affected Versions QEMU (aka Quick Emulator) versions prior to the fixed version

Description A memory leak issue exists in the v9fs link function, located in hw/9pfs/9p.c, allowing local guest OS administrators to cause a denial of service by consuming memory. This can be achieved through vectors involving a reference to the source fid object.

Recommendations For QEMU versions prior to the fixed version, update to the latest version to resolve the memory leak issue. As a temporary workaround, consider restricting access to the v9fs link function to minimize the risk of exploitation.
