The interrupt handler itself is guaranteed that\ntrigger is always valid between request_irq() and free_irq(), but\nthe loopback testing mechanisms to invoke the handler function\nneed to test the trigger.  The triggering and setting ioctl paths\nboth make use of igate and are therefore mutually exclusive.\n\nThe vfio-fsl-mc driver does not make use of irqfds, nor does it\nsupport any sort of masking operations, therefore unlike vfio-pci\nand vfio-platform, the flow can remain essentially unchanged."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/vfio/fsl-mc/vfio_fsl_mc_intr.c"],"versions":[{"version":"cc0ee20bd96971c10eba9a83ecf1c0733078a083","lessThan":"a563fc18583ca4f42e2fdd0c70c7c618288e7ede","status":"affected","versionType":"git"},{"version":"cc0ee20bd96971c10eba9a83ecf1c0733078a083","lessThan":"250219c6a556f8c69c5910fca05a59037e24147d","status":"affected","versionType":"git"},{"version":"cc0ee20bd96971c10eba9a83ecf1c0733078a083","lessThan":"083e750c9f5f4c3bf61161330fb84d7c8e8bb417","status":"affected","versionType":"git"},{"version":"cc0ee20bd96971c10eba9a83ecf1c0733078a083","lessThan":"ee0bd4ad780dfbb60355b99f25063357ab488267","status":"affected","versionType":"git"},{"version":"cc0ee20bd96971c10eba9a83ecf1c0733078a083","lessThan":"de87511fb0404d23b6da5f4660383b6ed095e28d","status":"affected","versionType":"git"},{"version":"cc0ee20bd96971c10eba9a83ecf1c0733078a083","lessThan":"6ec0d88166dac43f29e96801c0927d514f17add9","status":"affected","versionType":"git"},{"version":"cc0ee20bd96971c10eba9a83ecf1c0733078a083","lessThan":"7447d911af699a15f8d050dfcb7c680a86f87012","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/vfio/fsl-mc/vfio_fsl_mc_intr.c"],"versions":[{"version":"5.10","status":"affected"},{"version":"0","lessThan":"5.10","status":"unaffected","versionType":"semver"},{"version":"5.10.215","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.154","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.84","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.24","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.7.12","lessThanOrEqual":"6.7.*","status":"unaffected","versionType":"semver"},{"version":"6.8.3","lessThanOrEqual":"6.8.*","status":"unaffected","versionType":"semver"},{"version":"6.9","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":"5.10","versionEndExcluding":"5.10.215"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"5.15.154"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.1.84"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.6.24"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.7.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.8.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/a563fc18583ca4f42e2fdd0c70c7c618288e7ede"},{"url":"https://git.kernel.org/stable/c/250219c6a556f8c69c5910fca05a59037e24147d"},{"url":"https://git.kernel.org/stable/c/083e750c9f5f4c3bf61161330fb84d7c8e8bb417"},{"url":"https://git.kernel.org/stable/c/ee0bd4ad780dfbb60355b99f25063357ab488267"},{"url":"https://git.kernel.org/stable/c/de87511fb0404d23b6da5f4660383b6ed095e28d"},{"url":"https://git.kernel.org/stable/c/6ec0d88166dac43f29e96801c0927d514f17add9"},{"url":"https://git.kernel.org/stable/c/7447d911af699a15f8d050dfcb7c680a86f87012"}],"title":"vfio/fsl-mc:
