The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

tpm2-sessions: Fix missing tpm_buf_destroy() in tpm2_read_public()
tpm2_read_public() calls tpm_buf_init() but fails to call tpm_buf_destroy() on two exit paths, leaking a page allocation:
When name_size() returns an error (unrecognized hash algorithm), the function returns directly without destroying the buffer.
On the success path, the buffer is never destroyed before returning.
All other error paths in the function correctly call tpm_buf_destroy() before returning.
Fix both by adding the missing tpm_buf_destroy() calls.
