Linux 7.2-rc5 plugs critical module reference leaks in the fprobe subsystem while KVM tackles interrupt propagation bugs, as Basecamp's desktop shell strips Qt5 and ships plugin cloning.

Linus pulled probe fixes targeting out-of-bounds vulnerabilities and module cleanup failures that could leak reference counts on error paths [1] [2]. The fprobe fix ensures module_put() runs even when get_ips_from_filter() fails partway through, a critical safety net for kernel modules loaded via dynamic probes. Over on the KVM front, Paolo Bonzini's pull includes arm64 fixes for interrupt deactivation races and LPI mapping robustness [3], plus an x2APIC MSR intercept update that prevents L1 from reading host APIC state when AVIC gets inhibited mid-L2 execution [4]. On the userspace side, Basecamp shipped five major omarchy commits overhauling the bar plugin system, dropping the entire Qt5 stack (110 MiB gone) [5], and adding disk space checks before updates to prevent mid-upgrade failures [6]. The plugin management refactor consolidates widget activation and placement under a single `omarchy bar` command [7], while the new cloning UI lets users fork plugins directly from the Setup menu [8], with hot-reload support for local edits.
