Description OSIDB Bzimport 2026-01-23 15:02:48 UTC 
In the Linux kernel, the following vulnerability has been resolved:

KEYS: trusted: Fix a memory leak in tpm2_load_cmd

'tpm2_load_cmd' allocates a tempoary blob indirectly via 'tpm2_key_decode'
but it is not freed in the failure paths. Address this by wrapping the blob
into with a cleanup helper.
