An update to Linux kernel 6.19 has caused consistent startup issues (crashes) with MongoDB 8.0+. Strong confidence this issue is in the TCMalloc repo, related to TCMalloc violating the upstream rseq ABI. TCMalloc contributors are aware of this issue.

Impact
Any customer downloading MongoDB 8.0+ and using kernel version 6.19 will get crashes upon trying to run MongoDB. This includes installing using package managers or Docker.
