CVE-2026-46283

In the Linux kernel, the following vulnerability has been resolved: tpm: Use kfree_sensitive() to free auth session in tpm_dev_release() tpm_dev_release() uses plain kfree() to free chip->auth, which contains sensitive cryptographic material including HMAC session keys, nonces, and passphrase data (struct tpm2_auth). Every other code path that frees this structure uses kfree_sensitive() to zero the memory before releasing it: both tpm2_end_auth_session() and tpm_buf_check_hmac_response() do s
