Bugmon Analysis
Verified bug as reproducible on mozilla-central 20221013100028-3662e18e5c43.
The bug appears to have been introduced in the following build range:

Start: cd243979744cb162120fc13c0fe9ed4eb62bb6fe (20221011201302)
End: 2796a36d754343ffbe7ecce367ae76a26bf45b96 (20221011222538)
Pushlog: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=cd243979744cb162120fc13c0fe9ed4eb62bb6fe&tochange=2796a36d754343ffbe7ecce367ae76a26bf45b96

Keywords: regression
Whiteboard: [bugmon:confirm] → [bugmon:bisected,confirmed]
Group: core-security → layout-core-security

In that range, it'd be a regression from the refactoring in bug 1794456.

Looks like that bug has another ASAN regression already filed, bug 1795030; maybe this is a dupe or similar?

Flags: needinfo?(aethanyc)
Regressed by: 1794456

Yes, this is a dup of bug 1795030. I've verified that with the patch in bug 1795051, the testcase no longer triggers the use-after-poison. We've added testcases in bug 1795030 and bug 1795051, so the test coverage should be sufficient.

Status: NEW → RESOLVED
Closed: 2 years ago
Flags: needinfo?(aethanyc)
Resolution: --- → DUPLICATE

No valid actions for resolution (DUPLICATE).
Removing bugmon keyword as no further action possible. Please review the bug and re-add the keyword for further analysis.
