A fix is available — apply it.

In the Linux kernel, the following vulnerability has been resolved:

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.
