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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/clk/visconti/clkc.c"],"versions":[{"version":"b4cbe606dc3674b25cb661e7cd1a1c6ddaaafaaa","lessThan":"0e97c22b286e1918c6f48bad7e77fb8240a24b4a","status":"affected","versionType":"git"},{"version":"b4cbe606dc3674b25cb661e7cd1a1c6ddaaafaaa","lessThan":"9f756f1965bad65e6066608f33c36988cd10302a","status":"affected","versionType":"git"},{"version":"b4cbe606dc3674b25cb661e7cd1a1c6ddaaafaaa","lessThan":"1cc0539e5b0906bace15d3fc7347b344a017cc02","status":"affected","versionType":"git"},{"version":"b4cbe606dc3674b25cb661e7cd1a1c6ddaaafaaa","lessThan":"8f7980033e9f7ecaaecd873a0b5bf6b6c87d7e5a","status":"affected","versionType":"git"},{"version":"b4cbe606dc3674b25cb661e7cd1a1c6ddaaafaaa","lessThan":"5ecfa72e74c6e2a765fa5bc1da574e5beae588f2","status":"affected","versionType":"git"},{"version":"b4cbe606dc3674b25cb661e7cd1a1c6ddaaafaaa","lessThan":"39c0e6c844a14945040cca4ccf6997792ab764c4","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/clk/visconti/clkc.c"],"versions":[{"version":"5.17","status":"affected"},{"version":"0","lessThan":"5.17","status":"unaffected","versionType":"semver"},{"version":"6.1.188","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.157","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.110","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.17","versionEndExcluding":"6.1.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.17","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.17","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.17","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.17","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.17","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0e97c22b286e1918c6f48bad7e77fb8240a24b4a"},{"url":"https://git.kernel.org/stable/c/9f756f1965bad65e6066608f33c36988cd10302a"},{"url":"https://git.kernel.org/stable/c/1cc0539e5b0906bace15d3fc7347b344a017cc02"},{"url":"https://git.kernel.org/stable/c/8f7980033e9f7ecaaecd873a0b5bf6b6c87d7e5a"},{"url":"https://git.kernel.org/stable/c/5ecfa72e74c6e2a765fa5bc1da574e5beae588f2"},{"url":"https://git.kernel.org/stable/c/39c0e6c844a14945040cca4ccf6997792ab764c4"}],"title":"clk: visconti: Make sure clk_init_data is fully initialized","x_generator":{"engine":"bippy-1.2.0"}}}}
