@jaras hey cool 7-zip bug
https://securitylab.github.com/advisories/GHSL-2026-140_7-Zip/
Any opinion on exploitability on non-Windows? Your writeup talks about the filetype handler bypass for NTFS in 7z.dll… so while the BOF exists on all OS targets, maybe only exploitable with an evil .zip or .rar on Windows?
I’m just thinking about CI/CD tooling.

GHSL-2026-140: Heap Buffer Write Overflow in 7-Zip
A heap buffer overflow vulnerability (GHSL-2026-140) exists in 7-Zip version 26.00, caused by an under-allocation in the NTFS compressed stream buffer (GetCuSize shift UB), potentially allowing attackers to exploit this issue for arbitrary code execution.
