CVE-2024-47668 - Linux kernel Null Pointer Dereference

CVE ID : CVE-2024-47668
Published : Oct. 9, 2024, 3:15 p.m. | 24 minutes ago
Description : 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.
Severity: 0.0 | NA
