Similar for me on Dell XPS 13 9380 @ Fedora 40 [kernel 6.8.9] with Workstation Pro 17.5.2 and the 17.5.1 vmmon and vmnet modules/sources:

Same here on Ubuntu 24.04 kernel 6.8.0 (latest official kernel).

[kev1nweng]

Same issue here on 24.04 LTS with kernel 6.8.0-35. vmware-installer run into issues when installing VMX as well, failing to properly compile components.

[wokawoka]

Same issue here on ubuntu 24.04 LTS and kernel 6.7.10

[odravison]

Same here, but I’m facing an UBSAN error in Linux kernel code! Does anyone know how to solve the issue?

Kernel version is 6.8.0 I have tried changing it already but it didn’t work
