Vendor and ecosystem advisories describing this.

PUB-A-2166071182022-04-01vendor · osvUS
In exception handling functions of multiple files, there is a possible info leak due to side channel information disclosure. This could lead to local information disclosure from the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.
