CWE ID 362
Summary
CVE-2024-47668 is a vulnerability identified in the Linux kernel. It affects the lib/generic-radix-tree.c file and involves a rare race condition in the function __genradix_ptr_alloc(). If a thread increases the tree depth and a new node needs to be allocated, but another thread beats it to the punch, the newly allocated node might still contain a pointer to the old root instead of being zeroed. This issue has been resolved by ensuring the new node's root pointer is zeroed in the cmpxchg failure path.
