CVE-2026-53090

A flaw was found in the Linux kernel's Berkeley Packet Filter (BPF) verifier. When `ld_{abs,ind}` instructions are used in BPF subprograms, the verifier fails to correctly simulate the abnormal exit path if packet data loading fails. This oversight could lead to unexpected behavior or bypass of security checks within the BPF execution environment.
