If no supplier is\nregistered, power_supply_get_property_from_supplier() returns -ENODEV and\nleaves the output value untouched.\n\nmax17040_get_property() currently ignores that error and returns success,\nso userspace can read an uninitialized status value from the battery power\nsupply. This happens on systems that use the fuel gauge without a charger\nsupplier relationship in firmware.\n\nReturn POWER_SUPPLY_STATUS_UNKNOWN when no supplier provides STATUS, and\npropagate other supplier lookup errors."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/power/supply/max17040_battery.c"],"versions":[{"version":"f4b782af61ae7bbf93008d5809b0e3a8ac2bb88e","lessThan":"91ac995a6f4ddf4f92b231b080544abf23a9b871","status":"affected","versionType":"git"},{"version":"f4b782af61ae7bbf93008d5809b0e3a8ac2bb88e","lessThan":"b039f13e095d28a64ca6b21d0ee5440d8b048f37","status":"affected","versionType":"git"},{"version":"f4b782af61ae7bbf93008d5809b0e3a8ac2bb88e","lessThan":"ee2ea0c452edc0930e7395b080dccd5a1cb965e1","status":"affected","versionType":"git"},{"version":"f4b782af61ae7bbf93008d5809b0e3a8ac2bb88e","lessThan":"725668c6b6aa3971fe850659102c250d0d676e18","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/power/supply/max17040_battery.c"],"versions":[{"version":"6.7","status":"affected"},{"version":"0","lessThan":"6.7","status":"unaffected","versionType":"semver"},{"version":"6.12.103","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.44","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.8","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","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":"6.7","versionEndExcluding":"6.12.103"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.18.44"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"7.1.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/91ac995a6f4ddf4f92b231b080544abf23a9b871"},{"url":"https://git.kernel.org/stable/c/b039f13e095d28a64ca6b21d0ee5440d8b048f37"},{"url":"https://git.kernel.org/stable/c/ee2ea0c452edc0930e7395b080dccd5a1cb965e1"},{"url":"https://git.kernel.org/stable/c/725668c6b6aa3971fe850659102c250d0d676e18"}],"title":"power: supply: max17040: handle missing status supplier","x_generator":{"engine":"bippy-1.2.0"}}}}
