CVE-2026-64413 netfilter: ebtables: zero chainstack array

In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: zero chainstack array sashiko reports: looking at ebtables table translation, could a sparse cpupossiblemask lead to an uninitialized pointer free? If cpupossiblemask is sparse for example, CPU 0 and CPU 2 ar...

CVE-2026-64413

CVE-2026-64413 relates to the Linux kernel netfilter/ebtables path, specifically the zero chainstack array issue. The advisory describes that if cpu_possible_mask is sparse (e.g., CPU 0 and CPU 2 possible, CPU 1 not), the allocation loop can skip an entry and, if vmalloc_node() fails later, the c...
