CVE-2026-43343

CVE-2026-43343 affects the Linux kernel USB gadget f_subset code. The vulnerability stems from an unbalanced reference count: geth_alloc() increments the refcount, but geth_free() does not decrement it, which can block configuration of attributes via configfs after unlinking the function. The con...
