      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ntpm: fix off-by-four bounds check in tpm2_get_random()\n\nWhen the response carries the TPM2_ST_SESSIONS tag, tpm2_get_random()\nskips the 4-byte parameter size field before locating the random data,\nbut the bounds check still validates the response length against\nTPM_HEADER_SIZE.  A truncated response can pass the check and make\nmemcpy() read up to 4 bytes past the response end, so stale buffer\ncontents end up in the caller's random bytes.\n\nFix this by checking the response length against 'offset', which\nalready includes the skipped parameter size field.",
