CVE-2026-43333

In the Linux kernel, the following vulnerability has been resolved: bpf: reject direct access to nullable PTRTOBUF pointers checkmemaccess matches PTRTOBUF via basetype which strips PTRMAYBENULL, allowing direct dereference without a null check. Map iterator ctx-key and ctx-value are PTRTOBUF |...

CVE-2026-43321

The CVE-2026-43321 issue is in the Linux kernel BPF subsystem, where indirect jumps did not correctly mark the live registers for a gotox rX, leaving the affected register state unchecked. When the kernel fails to mark registers as used, it can enable manipulation of kernel state and potentially ...
