Hence a checkpoint\ncreated on such a path would prune against arbitrary scalar value.\n\ncheck_helper_call() enforces second parameter of the\nbpf_get_local_storage() to be zero, w/o marking the underlying scalar\nregister precise. Hence a checkpoint created on such a path would\nprune against arbitrary scalar value.\n\nGrouping these two into one patch, as they share the same fixes tag.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1a3a10b030c96ea88868ccc060a16827c01eaa5a","tags":[]},{"url":"https://git.kernel.org/stable/c/69a9ad004ccf5d45e534c7d503f47f643abe64b7","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
