My kernel version is ‘6.8.0-87-generic’ and hers is ‘6.14.00-33-generic’. My brother, who uses CachyOS, has kernel version ‘6.17.1-2-cachyos’. So it makes a little sense that the kernel is different. Even though I always thought that there was just one kernel that all Linux versions use.
But why is there a different kernel for the same distro?
That depends on the install date. If you installed Mint 22 when it was released you’re not on the HWE kernel. If you install a later version of Mint based on Ubuntu 24.04.2 or later you’ll get the HWE kernel which auto-updates to newer versions during the lifetime of the distro.
