Title
ima: Handle error code returned by ima_filter_rule_match()
Summary
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 security_audit_rule_match+0x60/0xa0 ima_match_rules+0x2e4/0x4a0 ima_match_policy+0x9c/0x1e8 ima_get_action+0x48/0x60 process_measurement+0xf8/0xa98 ima_bprm_check+0x98/0xd8 security_bprm_check+0x5c/0x78 search_binary_handler+0x6c/0x318 exec_binprm+0x58/0x1b8 bprm_execve+0xb8/0x130 do_execveat_common.isra.0+0x1a8/0x258 __arm64_sys_execve+0x48/0x68 invoke_syscall+0x50/0x128 el0_svc_common.constprop.0+0xc8/0xf0 do_el0_svc+0x24/0x38 el0_svc+0x44/0x200 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.

This causes the code to enter the \u0027if (rc == -ESTALE \u0026\u0026\\n!rule_reinitialized)\u0027 block, perform ima_lsm_copy_rule() and retry. In\\nima_lsm_copy_rule(), since the SELinux module has been removed, the rule\\nbecomes NULL, and the second call to ima_filter_rule_match() returns\\n-ENOENT. This bypasses the \u0027if (!rc)\u0027 check and results in a false match.\\n\\nCall trace:\\n  selinux_audit_rule_match+0x310/0x3b8\\n  security_audit_rule_match+0x60/0xa0\\n  ima_match_rules+0x2e4/0x4a0\\n  ima_match_policy+0x9c/0x1e8\\n  ima_get_action+0x48/0x60\\n  process_measurement+0xf8/0xa98\\n  ima_bprm_check+0x98/0xd8\\n  security_bprm_check+0x5c/0x78\\n  search_binary_handler+0x6c/0x318\\n  exec_binprm+0x58/0x1b8\\n  bprm_execve+0xb8/0x130\\n  do_execveat_common.isra.0+0x1a8/0x258\\n  __arm64_sys_execve+0x48/0x68\\n  invoke_syscall+0x50/0x128\\n  el0_svc_common.constprop.0+0xc8/0xf0\\n  do_el0_svc+0x24/0x38\\n  el0_svc+0x44/0x200\\n  el0t_64_sync_handler+0x100/0x130\\n  el0t_64_sync+0x3c8/0x3d0\\n\\nFix this by changing \u0027if (!rc)\u0027 to \u0027if (rc \u003c= 0)\u0027 to ensure that error\\ncodes like -ENOENT do not bypass the check and accidentally result in a\\nsuccessful match.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.10.248\", \"versionStartIncluding\": \"2.6.30\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.15.198\", \"versionStartIncluding\": \"2.6.30\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1.160\", \"versionStartIncluding\": \"2.6.30\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.120\", \"versionStartIncluding\": \"2.6.30\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.12.63\", \"versionStartIncluding\": \"2.6.30\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.17.13\", \"versionStartIncluding\": \"2.6.30\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.18.2\", \"versionStartIncluding\": \"2.6.30\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.19\", \"versionStartIncluding\": \"2.6.30\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-05-11T21:52:25.762Z\"}}}",
