CVE-2024-26690

In CVE-2024-26690, the Linux kernel stmmac driver fix avoids 32-bit seqcount race conditions in u64_stats_sync by splitting 64-bit statistics into three context-specific groups and introducing a per-cpu stats structure (stmmac_pcpu_stats). The tx, napi/poll, and interrupt contexts now update disj...
