low Tenable Cloud Security Plugin ID 465615

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: ima: Handle error code returned by
ima_filter_rule_match() In ima_match_rules(), if ima_filter_rule_match() returns -ENOENT due to the rule
being NULL, the function incorrectly skips the 'if (!rc)' check and sets 'result = true'. The LSM rule is
considered a match, causing extra files to be measured by IMA. This issue can be reproduced in the
following scenario: After unloading the SELinux policy module via 'semodule -d', if an IMA measurement is
triggered before ima_lsm_rules is updated, in ima_match_rules(), the first call to ima_filter_rule_match()
returns -ESTALE. This causes the code to enter the 'if (rc == -ESTALE && !rule_reinitialized)' block,
perform ima_lsm_copy_rule() and retry. In ima_lsm_copy_rule(), since the SELinux module has been removed,
the rule becomes NULL, and the second call to ima_filter_rule_match() returns -ENOENT. This bypasses the
'if (!rc)' check and results in a false match. Call trace: selinux_audit_rule_match+0x310/0x3b8

el0t_64_sync_handler+0x100/0x130 el0t_64_sync+0x3c8/0x3d0 Fix this by changing 'if (!rc)' to 'if (rc <=
0)' to ensure that error codes like -ENOENT do not bypass the check and accidentally result in a
successful match. (CVE-2025-68740)
