Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: tpm: efi: Use local variable for
 calculating final log size When tpm_read_log_efi is called multiple times, which happens when one loads
 and unloads a TPM2 driver multiple times, then the global variable efi_tpm_final_log_size will at some
 point become a negative number due to the subtraction of final_events_preboot_size occurring each time.
 Use a local variable to avoid this integer underflow. The following issue is now resolved: Mar 8 15:35:12
