CVE-2026-46110

A flaw was found in the Linux kernel's stmmac driver. When the system experiences receive RX memory exhaustion, the stmmacrx function can misinterpret already-processed data descriptors as valid, leading to a NULL pointer dereference. This vulnerability can cause the system to panic, resulting in...
