During removal,\nspi_bitbang_stop() only unregisters the controller; the subsequent\nspi_controller_put() then frees the controller together with its\nembedded driver-private devdata, which is the IRQ handler's dev_id.  The\ndevm_request_irq() release action (free_irq()), which drains the\nhandler, does not run until after .remove() returns.  A late or latched\ninterrupt can therefore reach tiny_spi_irq() and dereference\nalready-freed memory (e.g. hw->base).\n\nSwitch to devm_spi_alloc_host() so that the devres LIFO order releases\nthe controller only after free_irq() has drained the handler, and drop\nthe now-redundant spi_controller_put() from .remove().  The probe error\npath is simplified to direct returns.\n\nThis issue was found by an in-house static analysis tool."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/spi/spi-oc-tiny.c"],"versions":[{"version":"ce792580ea2ce6f7259b45124e9ccc4574c31606","lessThan":"0260c94453a08491640e61f8cf0c384edbe7bd11","status":"affected","versionType":"git"},{"version":"ce792580ea2ce6f7259b45124e9ccc4574c31606","lessThan":"ef5cc4a8c088d05549f71950a72b5deff5000fd7","status":"affected","versionType":"git"},{"version":"ce792580ea2ce6f7259b45124e9ccc4574c31606","lessThan":"1cd16c8d68f58e54abb8f331d05469237200631f","status":"affected","versionType":"git"},{"version":"ce792580ea2ce6f7259b45124e9ccc4574c31606","lessThan":"d710f43ce30975d197f73c543bfe47b958d8ba17","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-oc-tiny.c"],"versions":[{"version":"2.6.39","status":"affected"},{"version":"0","lessThan":"2.6.39","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":"2.6.39","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.39","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.39","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.39","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0260c94453a08491640e61f8cf0c384edbe7bd11"},{"url":"https://git.kernel.org/stable/c/ef5cc4a8c088d05549f71950a72b5deff5000fd7"},{"url":"https://git.kernel.org/stable/c/1cd16c8d68f58e54abb8f331d05469237200631f"},{"url":"https://git.kernel.org/stable/c/d710f43ce30975d197f73c543bfe47b958d8ba17"}],"title":"spi: oc-tiny: switch to managed controller allocation","x_generator":{"engine":"bippy-1.2.0"}}}}
