CVE-2026-64173 Details
Description
In the Linux kernel, the following vulnerability has been resolved: tracing: Do not call map->ops->elt_free() if elt_alloc() fails In paths where tracing_map_elt_alloc() failed to allocate objects, the map->ops->elt_alloc() call was never successful. In this case, map->ops->elt_free() should not be called.
A vulnerability exists in the Linux kernel's handling of tracing map elements, specifically in the memory management functions. When the element allocation function fails, the corresponding free function should not be called. However, the current implementation incorrectly attempts to free memory for elements that were not successfully allocated, which can lead to memory management issues.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
