Description secureblue 2024-02-20 03:54:38 UTC

Setting -ftrivial-auto-var-init=zero initializes automatic variables with either a pattern or with zeroes to increase the security and predictability of a program by preventing uninitialized memory disclosure and use.

Other chromium distributions already do this: https://github.com/GrapheneOS/Vanadium/blob/main/patches/0005-enable-ftrivial-auto-var-init-zero.patch

This isn't a chromium default due to what seems to be some performance overhead: https://issues.chromium.org/issues/40633061

Reproducible: Always
