TIMELINE Sep 30 Reserved by Linux Oct 9 Published (CNA: Linux) Aug 4 RESCORED — CVE-2024-47668 (Linux). CVSS 7.8 → 4.7 (NVD).
In the Linux kernel, the following vulnerability has been resolved: lib/generic-radix-tree.c: Fix rare race in __genradix_ptr_alloc() If we need to increase the tree depth, allocate a new node, and then race with another thread that increased the tree depth before us, we'll still have a preallocated node that might be used later. If we then use that node for a new non-root node, it'll still have a pointer to the old root instead of being zeroed - fix this by zeroing it in the cmpxchg failure path.
