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\naml_spisg_clk_init() 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/spi/spi-amlogic-spisg.c"],"versions":[{"version":"cef9991e04aed3305c61c392e880f6e01a0c2ea4","lessThan":"bfce0f324efaa605e606cbb3f0bdb8fe5c910c11","status":"affected","versionType":"git"},{"version":"cef9991e04aed3305c61c392e880f6e01a0c2ea4","lessThan":"5969a3df8361a0e20379a308c2313d3e263123de","status":"affected","versionType":"git"},{"version":"cef9991e04aed3305c61c392e880f6e01a0c2ea4","lessThan":"b2702908ee23ef31bfcf241a2e07ace0eb76bd71","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/spi/spi-amlogic-spisg.c"],"versions":[{"version":"6.17","status":"affected"},{"version":"0","lessThan":"6.17","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":"6.17","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.17","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.17","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/bfce0f324efaa605e606cbb3f0bdb8fe5c910c11"},{"url":"https://git.kernel.org/stable/c/5969a3df8361a0e20379a308c2313d3e263123de"},{"url":"https://git.kernel.org/stable/c/b2702908ee23ef31bfcf241a2e07ace0eb76bd71"}],"title":"spi: amlogic-spisg: Make sure clk_init_data is fully initialized","x_generator":{"engine":"bippy-1.2.0"}}}}
