  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nKEYS: trusted: Fix a memory leak in tpm2_load_cmd\n'tpm2_load_cmd' allocates a tempoary blob indirectly via 'tpm2_key_decode'\nbut it is not freed in the failure paths. Address this by wrapping the blob\ninto with a cleanup helper.", "A flaw was found in the Linux kernel's trusted keys subsystem. A local user could exploit a memory leak in the `tpm2_load_cmd` function, which fails to free a temporary memory allocation in certain error scenarios. This memory leak could lead to a system-wide Denial of Service (DoS) by exhausting available memory resources." ],
