CVSS v3.1 |
| Kobako is a Ruby gem that embeds a Wasm-isolated mruby interpreter inside applications, allowing execution of untrusted Ruby scripts (LLM-generated code, user formulas, student submissions, third-party plugins) in-process without giving them access to host memory, files, network, or credentials. From version 0.1.0 to before version 0.9.1, a guest mruby script running inside the Kobako sandbox can execute arbitrary Ruby in the host process, fully escaping the sandbox. This issue has been patched in version 0.9.1. |
| A flaw was found in Moodle. An authenticated attacker can supply an improperly validated audience class name to the Report Builder component, allowing arbitrary class instantiation. This vulnerability enables the unauthorized creation of internal program objects, which may result in unexpected application behavior. |
| In the Linux kernel, the following vulnerability has been resolved:
x86/amd_node: Fix potential NULL pointer dereference
amd_smn_read/write() are exported functions around __amd_smn_rw(), so
they are always available even if amd_smn_init() fails. In that case,
'amd_roots' is NULL and __amd_smn_rw() will access uninitialized memory.
Then, commit:
83518453074d ("x86/amd_node: Add SMN offsets to exclusive region access")
added the 'smn_exclusive' flag, which indicated the calls to
pci_request_config_region_exclusive() succeeded, to prevent
concurrent userspace access.
Commit:
0a4b61d9c2e4 ("x86/amd_node: Fix AMD root device caching")
re-ordered initialization so pci_request_config_region_exclusive() is
called earlier and a failure exits amd_smn_init() before allocating
'amd_roots'. The setting of 'smn_exclusive' moved to the end of
amd_smn_init(), after 'amd_roots' is allocated. It became redundant
and can be removed.
Replace 'smn_exclusive' with directly checking 'amd_roots', to fix a
potential NULL pointer dereference and to simplify the logic.

| A flaw was found in KubeVirt. An authenticated user with permission to create Virtual Machine Instances (VMIs) can cause a Denial of Service (DoS) by submitting a virtual machine definition with an empty ephemeral volume. The virt-controller component fails to properly validate the volume configuration, leading to an unhandled exception and application crash during processing. Because the malformed definition persists in the cluster, the controller enters a continuous crash loop, disrupting virtual machine lifecycle operations across the entire environment. |
| Deserialization of untrusted data in the model loading component in Amazon GluonTS before 0.17.0 might allow context-dependent attackers to execute arbitrary operating system commands with the privileges of the loading process via a crafted serialized model directory.
To remediate this issue, users should upgrade to version 0.17.0 or later. |

| In the Linux kernel, the following vulnerability has been resolved:
bpf: Mark the zero register precise for a register-form NULL check
check_cond_jmp_op() accepts "if rA <op> rB" as a NULL check for a
nullable pointer rA when rB is a scalar known to be zero,
lifts PTR_MAYBE_NULL from rA in the corresponding branch and does not
mark rB precise. Consider the following program:
r0 = bpf_get_prandom_u32();
r6 = 1; /* the r6 == 0 path is explored first */
if (r0 == 0) goto 1f;
r6 = 0;
1:
r0 = bpf_map_lookup_elem(map, &0); /* absent, NULL at runtime */
if (r0 == r6) goto 2f; /* taken as a NULL check for r0 */
*(u8 *)(r0 + 0); /* verifier: map value; runtime: zero */
2:
return 0;
The r6 == 0 path is explored first and the dereference is accepted.
The r6 == 1 path is pruned at the checkpoint recorded for (1),
so the comparison is never verified with a non-zero r6. At runtime a
failed lookup returns NULL, NULL != 1 takes the non-NULL edge and the
program dereferences a pointer that is zero. |
| A database user able to create a view in a namespace that MongoDB Connector for BI samples can cause the schema-sampling routine to stop functioning by defining a view whose evaluation reliably fails. The sampling logic classifies the resulting server message as transient and, after the configured retries are exhausted, proceeds without a valid result, ending the schema refresh routine. The mongosqld process continues running without a usable schema, so SQL clients are unable to obtain results until an operator removes the view or excludes its namespace from sampling. |
