Witrynasensitive lockset analysis, which is oblivious of the related contexts around the deadlock cycles. In this work, to reduce the irrelevant calling contexts, Peahen decomposes the cost of reaching high-fidelity by first efficiently constructing a context-insensitive and smaller lock graph.

We have evaluated DCUAF on the driver code of Linux 4.19, and found 640 real concurrency use-after-free bugs. We have randomly selected 130 of the real bugs and reported them to Linux kernel developers, and 95 have been …
