In the Linux kernel, the following vulnerability has been resolved: bpf: Cancel special fields on map value recycle Map update and delete paths… (CVE-2026-74314)CVE-2026-74314 0 A vulnerability in the Linux kernel's BPF subsystem related to map value recycling has been resolved. The issue involved unsafe destruction of special fields during map update and delete operations, particularly in contexts like NMI where certain destructors are unsafe. The fix introduces a safer cancellation method for reusable values that performs only NMI-safe cleanup, deferring full destruction to a final cleanup path. This change relaxes previous eager-free semantics, which may affect programs relying on immediate freeing of recycled map slots.
