Title
usb: gadget: net2280: Fix double free in probe error path
Summary
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: net2280: Fix double free in probe error path usb_initialize_gadget() installs gadget_release() as the release callback for the embedded gadget device. The struct net2280 instance is therefore released through gadget_release() when the gadget device's last reference is dropped. The probe error path calls net2280_remove(), which tears down the partially initialized device and drops the gadget reference with usb_put_gadget(). Calling kfree(dev) afterwards can free the same object again. Drop the explicit kfree() and let the gadget device release callback handle the final free. This issue was found by a static analysis tool I am developing.

The struct net2280 instance is\\ntherefore released through gadget_release() when the gadget device\u0027s last\\nreference is dropped.\\n\\nThe probe error path calls net2280_remove(), which tears down the\\npartially initialized device and drops the gadget reference with\\nusb_put_gadget().  Calling kfree(dev) afterwards can free the same object\\nagain.\\n\\nDrop the explicit kfree() and let the gadget device release callback\\nhandle the final free.  This issue was found by a static analysis tool\\nI am developing.\"}],\"affected\":[{\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"affectedData\":[{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"unaffected\",\"programFiles\":[\"drivers/usb/gadget/udc/net2280.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"f770fbec4165b1acfabdeadb01ad6008d2c537b5\",\"lessThan\":\"71b3391dc81655ff058492f8e9d013b2c6e5747b\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"f770fbec4165b1acfabdeadb01ad6008d2c537b5\",\"lessThan\":\"550fa4d071a8c8e53072900869d37ae6abf4999d\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"f770fbec4165b1acfabdeadb01ad6008d2c537b5\",\"lessThan\":\"c5b9fdb1e8ddf50bc6272927edb118679f170350\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"f770fbec4165b1acfabdeadb01ad6008d2c537b5\",\"lessThan\":\"085652fda7f38040d1a2c42d72614f418feb843f\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"f770fbec4165b1acfabdeadb01ad6008d2c537b5\",\"lessThan\":\"48f89ead20e48d447ad29fa937b43b9fa981cf28\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"f770fbec4165b1acfabdeadb01ad6008d2c537b5\",\"lessThan\":\"e6f8be12f0307145b9a6010f044925952b37de8b\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"f770fbec4165b1acfabdeadb01ad6008d2c537b5\",\"lessThan\":\"db2b72e83a0208ae2b3b270bf91662b1c6849a9b\",\"versionType\":\"git\",\"status\":\"affected\"},{\"version\":\"f770fbec4165b1acfabdeadb01ad6008d2c537b5\",\"lessThan\":\"c8547c74988e0b5f4cbb1b895e2a57aae084f070\",\"versionType\":\"git\",\"status\":\"affected\"}]},{\"vendor\":\"Linux\",\"product\":\"Linux\",\"defaultStatus\":\"affected\",\"programFiles\":[\"drivers/usb/gadget/udc/net2280.c\"],\"repo\":\"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\"versions\":[{\"version\":\"5.10\",\"status\":\"affected\"},{\"version\":\"0\",\"lessThan\":\"5.10\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.10.259\",\"lessThanOrEqual\":\"5.10.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"5.15.210\",\"lessThanOrEqual\":\"5.15.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.1.176\",\"lessThanOrEqual\":\"6.1.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.6.143\",\"lessThanOrEqual\":\"6.6.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.12.93\",\"lessThanOrEqual\":\"6.12.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"6.18.35\",\"lessThanOrEqual\":\"6.18.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"7.0.12\",\"lessThanOrEqual\":\"7.0.*\",\"versionType\":\"semver\",\"status\":\"unaffected\"},{\"version\":\"7.1\",\"lessThanOrEqual\":\"*\",\"versionType\":\"original_commit_for_fix\",\"status\":\"unaffected\"}]}]}],\"metrics\":{},\"references\":[{\"url\":\"https://git.kernel.org/stable/c/085652fda7f38040d1a2c42d72614f418feb843f\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/48f89ead20e48d447ad29fa937b43b9fa981cf28\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/550fa4d071a8c8e53072900869d37ae6abf4999d\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/71b3391dc81655ff058492f8e9d013b2c6e5747b\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/c5b9fdb1e8ddf50bc6272927edb118679f170350\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/c8547c74988e0b5f4cbb1b895e2a57aae084f070\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/db2b72e83a0208ae2b3b270bf91662b1c6849a9b\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/e6f8be12f0307145b9a6010f044925952b37de8b\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"}]}}",
