"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntpm: Use kfree_sensitive() to free auth session in tpm_dev_release()\n\ntpm_dev_release() uses plain kfree() to free chip->auth, which contains\nsensitive cryptographic material including HMAC session keys, nonces,\nand passphrase data (struct tpm2_auth).\n\nEvery other code path that frees this structure uses kfree_sensitive()\nto zero the memory before releasing it: both tpm2_end_auth_session()\nand tpm_buf_check_hmac_response() do so. The tpm_dev_release() path\nis the only one that does not, leaving key material in freed slab\nmemory until it is eventually overwritten.\n\nUse kfree_sensitive() for consistency with the rest of the driver and\nto ensure session keys are scrubbed during device teardown."
