Write access to cache directory requires specific positioning (AC:H); arbitrary pickle deserialization yields full code execution, warranting C:H/I:H/A:H.

Lifecycle Timeline
2DescriptionCVE.org
A weakness has been identified in tile-ai tilelang up to 0.1.14. This impacts the function KernelCache._load_kernel_from_disk of the file tilelang/cache/kernel_cache.py of the component Kernel Cache. Executing a manipulation can lead to deserialization. The attack may be performed from remote. This patch is called 11ec2397fe942e8b422d026af4a03d6e0a55ae6c. Applying a patch is advised to resolve this issue. Based on the release information, the fix has not been included in any official release yet.
AnalysisAI
Deserialization of untrusted data in tile-ai tilelang versions 0.1.0 through 0.1.14 allows an attacker who can write to the kernel cache directory to achieve arbitrary code execution by planting a crafted params.pkl file in the cache path. The KernelCache._load_kernel_from_disk function previously used cloudpickle to deserialize cached kernel parameters from disk without validation, a classic CWE-502 pattern that permits executing arbitrary Python code at deserialization time. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to have write access to the tilelang kernel cache directory - this is the primary gating condition. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The reported CVSS 4.0 score is 5.1 with vector AV:N/AC:L/AT:N/PR:L/UI:P/VC:L/VI:L/VA:L, but the C/I/A impact metrics (all Low) substantially understate the actual post-exploitation impact: arbitrary pickle deserialization in Python yields full code execution within the victim process, warranting C:H/I:H/A:H. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upstream fix available (PR/commit); released patched version not independently confirmed. … Detailed patch versions, workarounds, and compensating controls in full report. |
