CVE-2026-46306

CVE-2026-46306 affects the Linux kernel where the flow_dissector incorrectly dissects PPPoE PFC frames. The root cause is handling a compressed (1-byte) Protocol Field Compression (PFC) in PPPoE, which shifts the subsequent PPP payload by one byte, causing a 4-byte network-header misalignment and...

CVE-2026-46250

A flaw was found in the Linux kernel, specifically affecting the MIPS architecture when compiled with LLVM. This vulnerability occurs because LLVM incorrectly restores the $gp register, which is used as a global register variable, after it has been intentionally modified during kernel relocation...
