Since every gpio chip instance\nrepresents an entire bank of 32 pins, if 'mediatek_gpio_irq_type()' is\ncalled concurrently for different IRQs on the same bank a possible overwrite\nof each other's configuration is possible. Thus, protect this state with\n'gpio_generic_lock_irqsave' lock in the same way it is handled in irp_chip\n'mediatek_gpio_irq_mask()' and 'mediatek_gpio_irq_unmask()' callbacks."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpio/gpio-mt7621.c"],"versions":[{"version":"4ba9c3afda41213ec98c30053e32963892e6dc7c","lessThan":"bddf9314a57a243dd11ed945ba11e146e331257e","status":"affected","versionType":"git"},{"version":"4ba9c3afda41213ec98c30053e32963892e6dc7c","lessThan":"207d3ebf36f654a43a934addeb4d6775cb2dd667","status":"affected","versionType":"git"},{"version":"4ba9c3afda41213ec98c30053e32963892e6dc7c","lessThan":"877a243006788aaa586b2d087f27c9f3628071b0","status":"affected","versionType":"git"},{"version":"4ba9c3afda41213ec98c30053e32963892e6dc7c","lessThan":"d3b9026ef78da3018a7d2c5a9c9d611de6d45c47","status":"affected","versionType":"git"},{"version":"4ba9c3afda41213ec98c30053e32963892e6dc7c","lessThan":"a60a40c9ba30edd06d3fb4215fdf430ed968728e","status":"affected","versionType":"git"},{"version":"4ba9c3afda41213ec98c30053e32963892e6dc7c","lessThan":"1781172526d1092323af443fa03f00e6de560401","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/gpio/gpio-mt7621.c"],"versions":[{"version":"4.19","status":"affected"},{"version":"0","lessThan":"4.19","status":"unaffected","versionType":"semver"},{"version":"6.1.184","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.148","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.101","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.40","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.5","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":"4.19","versionEndExcluding":"6.1.184"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19","versionEndExcluding":"6.6.148"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19","versionEndExcluding":"6.12.101"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19","versionEndExcluding":"6.18.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.19","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/bddf9314a57a243dd11ed945ba11e146e331257e"},{"url":"https://git.kernel.org/stable/c/207d3ebf36f654a43a934addeb4d6775cb2dd667"},{"url":"https://git.kernel.org/stable/c/877a243006788aaa586b2d087f27c9f3628071b0"},{"url":"https://git.kernel.org/stable/c/d3b9026ef78da3018a7d2c5a9c9d611de6d45c47"},{"url":"https://git.kernel.org/stable/c/a60a40c9ba30edd06d3fb4215fdf430ed968728e"},{"url":"https://git.kernel.org/stable/c/1781172526d1092323af443fa03f00e6de560401"}],"title":"gpio: mt7621: avoid corruption of shared interrupt trigger state","x_generator":{"engine":"bippy-1.2.0"}}}}
