CVE-2026-98834 is a known-severity vulnerability. It was published on October 18, 2026.
Technical description
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.
