However,\nnot initializing all members may cause subtle issues, which are only\nexposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is\nenabled.\n\nvisconti_clk_register_gate() fills in init.parent_data, and assumes that\ninit.parent_names is NULL.  However, the latter in uninitialized, and\nthus may cause a crash.\n\nMake sure all members are fully initialized, to fix such bugs, and to\navoid future breakage when converting drivers to a different method for\nspecifying the parents.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0e97c22b286e1918c6f48bad7e77fb8240a24b4a","tags":[]},{"url":"https://git.kernel.org/stable/c/1cc0539e5b0906bace15d3fc7347b344a017cc02","tags":[]},{"url":"https://git.kernel.org/stable/c/39c0e6c844a14945040cca4ccf6997792ab764c4","tags":[]},{"url":"https://git.kernel.org/stable/c/5ecfa72e74c6e2a765fa5bc1da574e5beae588f2","tags":[]},{"url":"https://git.kernel.org/stable/c/8f7980033e9f7ecaaecd873a0b5bf6b6c87d7e5a","tags":[]},{"url":"https://git.kernel.org/stable/c/9f756f1965bad65e6066608f33c36988cd10302a","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
