Each\nof_clk_add_provider() allocates a struct of_clk_provider, takes a\nreference on the OF node and adds an entry to the global of_clk_providers\nlist, none of which is released when the device is unbound. Every\nbind/unbind (or module reload) therefore leaks a provider structure and\nan of_node reference.\n\nThe clock itself is already device-managed (devm_clk_register()); only\nthe provider registration was not. Use devm_of_clk_add_hw_provider() so\nthe provider is removed automatically on unbind. Tie it to the parent\ni2c device, whose OF node carries the #clock-cells and clock-output-names\nproperties (the RTC class device has no OF node of its own)."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/rtc/rtc-pcf8563.c"],"versions":[{"version":"a39a6405d5f949bc651694028a55d74c514ef1f9","lessThan":"2b5622cf4ee218b6f98d31dbf3fbd44b9b6bd675","status":"affected","versionType":"git"},{"version":"a39a6405d5f949bc651694028a55d74c514ef1f9","lessThan":"36cb00c33bd83e7ce31b5a9f1f7c70db0cb7776c","status":"affected","versionType":"git"},{"version":"a39a6405d5f949bc651694028a55d74c514ef1f9","lessThan":"30b7c63af50fe1464e7582a37de1ca4bd030ecc1","status":"affected","versionType":"git"},{"version":"a39a6405d5f949bc651694028a55d74c514ef1f9","lessThan":"7afb8db47c4f107bce89cfe5115fb31ba7c94665","status":"affected","versionType":"git"},{"version":"a39a6405d5f949bc651694028a55d74c514ef1f9","lessThan":"97edf3fd9a46ea89a167966991c0449cfa07b36f","status":"affected","versionType":"git"},{"version":"a39a6405d5f949bc651694028a55d74c514ef1f9","lessThan":"08a59c28c2bdbcd655e99526c86a41dc83834283","status":"affected","versionType":"git"},{"version":"a39a6405d5f949bc651694028a55d74c514ef1f9","lessThan":"6218c0533a72235ec9c5f41b812c63d963bd4a3e","status":"affected","versionType":"git"},{"version":"a39a6405d5f949bc651694028a55d74c514ef1f9","lessThan":"9c48a53685040bb0de45a640b34055cbbfc69d4f","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/rtc/rtc-pcf8563.c"],"versions":[{"version":"4.4","status":"affected"},{"version":"0","lessThan":"4.4","status":"unaffected","versionType":"semver"},{"version":"5.10.270","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.221","lessThanOrEqual":"5.15.*","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":"4.4","versionEndExcluding":"5.10.270"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4","versionEndExcluding":"5.15.221"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4","versionEndExcluding":"6.1.188"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4","versionEndExcluding":"6.6.157"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/2b5622cf4ee218b6f98d31dbf3fbd44b9b6bd675"},{"url":"https://git.kernel.org/stable/c/36cb00c33bd83e7ce31b5a9f1f7c70db0cb7776c"},{"url":"https://git.kernel.org/stable/c/30b7c63af50fe1464e7582a37de1ca4bd030ecc1"},{"url":"https://git.kernel.org/stable/c/7afb8db47c4f107bce89cfe5115fb31ba7c94665"},{"url":"https://git.kernel.org/stable/c/97edf3fd9a46ea89a167966991c0449cfa07b36f"},{"url":"https://git.kernel.org/stable/c/08a59c28c2bdbcd655e99526c86a41dc83834283"},{"url":"https://git.kernel.org/stable/c/6218c0533a72235ec9c5f41b812c63d963bd4a3e"},{"url":"https://git.kernel.org/stable/c/9c48a53685040bb0de45a640b34055cbbfc69d4f"}],"title":"rtc: pcf8563: fix clock provider leak on unbind","x_generator":{"engine":"bippy-1.2.0"}}}}
