  3. CVE-2024-42255
In the Linux kernel, the following vulnerability has been resolved: tpm: Use auth only after NULL check in tpm_buf_check_hmac_response() Dereference auth after NULL check in tpm_buf_check_hmac_response(). Otherwise, unless tpm2_sessions_init() was called, a call can cause NULL dereference, when TCG_TPM2_HMAC is enabled. [jarkko: adjusted the commit message.]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tpm: use autenticación solo después de la verificación NULL en tpm_buf_check_hmac_response() Desreferenciar la autenticación después de la verificación NULL en tpm_buf_check_hmac_response(). De lo contrario, a menos que se haya llamado a tpm2_sessions_init(), una llamada puede causar una desreferencia NULL, cuando TCG_TPM2_HMAC está habilitado. [jarkko: ajustó el mensaje de confirmación.]
