{"id":"CVE-2026-72062","summary":"gpio: mt7621: avoid corruption of shared interrupt trigger state","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: mt7621: avoid corruption of shared interrupt trigger state\n\nThe bank-shared fields like 'rising' and 'falling' are modified using\nnon-atomic read-modify-write operations. 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.","modified":"2026-08-25T03:51:31.733396622Z","published":"2026-08-15T05:52:16.564Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72062.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1781172526d1092323af443fa03f00e6de560401"},{"type":"WEB","url":"https://git.kernel.org/stable/c/207d3ebf36f654a43a934addeb4d6775cb2dd667"},{"type":"WEB","url":"https://git.kernel.org/stable/c/877a243006788aaa586b2d087f27c9f3628071b0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a60a40c9ba30edd06d3fb4215fdf430ed968728e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bddf9314a57a243dd11ed945ba11e146e331257e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d3b9026ef78da3018a7d2c5a9c9d611de6d45c47"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72062.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72062"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4ba9c3afda41213ec98c30053e32963892e6dc7c"},{"fixed":"bddf9314a57a243dd11ed945ba11e146e331257e"},{"fixed":"207d3ebf36f654a43a934addeb4d6775cb2dd667"},{"fixed":"877a243006788aaa586b2d087f27c9f3628071b0"},{"fixed":"d3b9026ef78da3018a7d2c5a9c9d611de6d45c47"},{"fixed":"a60a40c9ba30edd06d3fb4215fdf430ed968728e"},{"fixed":"1781172526d1092323af443fa03f00e6de560401"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72062.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.19.0"},{"fixed":"6.1.184"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72062.json"}}],"schema_version":"1.9.0"}
