udf: Fix preallocation discarding at indirect extent boundary
Noroxi assessment
Priority: Monitor (action score 22/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.25% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: Linux Linux 12a88f572d6d94b5c0b72e2d1782cc2e96ac06cf, 1a075f4a549481ce6e8518d8379f193ccec6b746, 4d835efd561dfb9bf5409f11f4ecd428d5d29226.
Low priority for now. Upgrade to Linux Linux 12a88f572d6d94b5c0b72e2d1782cc2e96ac06cf, 1a075f4a549481ce6e8518d8379f193ccec6b746, 4d835efd561dfb9bf5409f11f4ecd428d5d29226 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: udf: Fix preallocation discarding at indirect extent boundary When preallocation extent is the first one in the extent block, the code would corrupt extent tree header instead. Fix the problem and use udf_delete_aext() for deleting extent to avoid some code duplication.

No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
