Title
ima: Fix memory leak in __ima_inode_hash()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ima: Fix memory leak in __ima_inode_hash()
Commit f3cc6b25dcc5 ("ima: always measure and audit files in policy") lets
measurement or audit happen even if the file digest cannot be calculated.
As a result, iint->ima_hash could have been allocated despite
ima_collect_measurement() returning an error.
Since ima_hash belongs to a temporary inode metadata structure, declared
at the beginning of __ima_inode_hash(), just add a kfree() call if
ima_collect_measurement() returns an error different from -ENOMEM (in that
case, ima_hash should not have been allocated).
Severity
No CVSS data available.
