CVE-2026-46100

A flaw was found in the Linux kernel's AFS (Andrew File System) component. The mmap_prepare() function was incorrectly used, leading to a reference count (refcount) leak. This issue occurs when mmap_prepare() establishes a refcount, but a subsequent operation fails, causing the refcount to be leaked. This resource leak could potentially lead to system instability or Denial of Service (DoS) over time.
