Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> libceph: guard missing CRUSH type name lookup<br /> <br /> Localized read selection can walk a parent bucket whose name exists in<br /> the CRUSH map while its type has no matching entry in type_names.<br /> get_immediate_parent() then dereferences a NULL type_cn and passes an<br /> invalid pointer into strcmp(), causing a null-ptr-deref.<br /> <br /> Skip such malformed parent buckets unless both the bucket name and type<br /> name metadata are present. This keeps malformed hierarchy data from<br /> crashing locality lookup and safely falls back to "not local".<br /> <br /> [ idryomov: add WARN_ON_ONCE ]
