The panic\ninvolves a somewhat complicated interaction between the kernel driver\nand a userspace component (as described in the Link tag below), but\nthe analysis did make one thing clear: The Gadget core should\naccomodate gadget drivers calling usb_gadget_deactivate() as part of\ntheir unbind procedure.\n\nCurrently this doesn't work.  gadget_unbind_driver() calls\ndriver->unbind() while holding the udc->connect_lock mutex, and\nusb_gadget_deactivate() attempts to acquire that mutex, which will\nresult in a deadlock.\n\nThe simple fix is for gadget_unbind_driver() to release the mutex when\ninvoking the ->unbind() callback.  There is no particular reason for\nit to be holding the mutex at that time, and the mutex isn't held\nwhile the ->bind() callback is invoked.  So we'll drop the mutex\nbefore performing the unbind callback and reacquire it afterward.\n\nWe'll also add a couple of comments to usb_gadget_activate() and\nusb_gadget_deactivate().  Because they run in process context they\nmust not be called from a gadget driver's ->disconnect() callback,\nwhich (according to the kerneldoc for struct usb_gadget_driver in\ninclude/linux/usb/gadget.h) may run in interrupt context.  This may\nhelp prevent similar bugs from arising in the future."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/usb/gadget/udc/core.c"],"versions":[{"version":"d8195536ce2624e2947d9f56b1a61e7a27874bd3","lessThan":"bed19d95fcb9c98dfaa9585922b39a2dfba7898d","status":"affected","versionType":"git"},{"version":"286d9975a838d0a54da049765fa1d1fb96b89682","lessThan":"8c1edc00db65f6d4408b3d1cd845e8da3b9e0ca4","status":"affected","versionType":"git"},{"version":"286d9975a838d0a54da049765fa1d1fb96b89682","lessThan":"65dadb2beeb7360232b09ebc4585b54475dfee06","status":"affected","versionType":"git"},{"version":"85102a45c7390caf124a3a5796574446f1e037b9","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/usb/gadget/udc/core.c"],"versions":[{"version":"6.4","status":"affected"},{"version":"0","lessThan":"6.4","status":"unaffected","versionType":"semver"},{"version":"6.1.46","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.4.11","lessThanOrEqual":"6.4.*","status":"unaffected","versionType":"semver"},{"version":"6.5","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":"6.1.35","versionEndExcluding":"6.1.46"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"6.4.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.4","versionEndExcluding":"6.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.3.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/bed19d95fcb9c98dfaa9585922b39a2dfba7898d"},{"url":"https://git.kernel.org/stable/c/8c1edc00db65f6d4408b3d1cd845e8da3b9e0ca4"},{"url":"https://git.kernel.org/stable/c/65dadb2beeb7360232b09ebc4585b54475dfee06"}],"title":"USB: Gadget: core: Help prevent panic during UVC unconfigure","x_generator":{"engine":"bippy-1.2.0"}}}}
