In the Linux kernel, the following vulnerability has been resolved:
mtd: core: avoid double-free of OTP NVMEM device
If factory OTP setup fails after the user OTP NVMEM device has been registered, mtd_otp_nvmem_add() unregisters the user device but leaves mtd->otp_user_nvmem set. On an error, the caller unregisters it again. For -EOPNOTSUPP, registration continues and normal teardown unregisters it again.
Clear mtd->otp_user_nvmem after unregistering it.
