Name of the Vulnerable Software and Affected Versions Linux Kernel (affected versions not specified)

Description An issue exists in the Linux kernel regarding the analysis of failure paths for ld abs and ld ind instructions within subprograms. These instructions are permitted in subprograms that are BTF annotated and utilize scalar return types. The verifier failed to simulate the abnormal exit path (where r0=0 and the program exits) that occurs when packet data loading via ld abs or ld ind fails, only accounting for the success path.
