Insufficient checks when processing graphics shared memory could have led to memory corruption. This could be leveraged by an attacker to perform a sandbox escape.
Incomplete WebAssembly exception handing could have led to a use-after-free.
Editor code failed to check an attribute value. This could have led to an out-of-bounds read.
It was possible for a web extension with minimal permissions to create a StreamFilter which could be used to read and modify the response body of requests on any site.
ANGLE failed to initialize parameters which led to reading from uninitialized memory. This could be leveraged to leak sensitive data from memory.
Unexpected marking work at the start of sweeping could have led to a use-after-free.
The date picker could partially obscure security prompts. This could be used by a malicious site to trick a user into granting permissions.
