CVE-2026-23106

CVE-2026-23106 concerns the Linux kernel timekeeping subsystem. The root cause is in __do_adjtimex(), which incorrectly references the core timekeeper’s tk_core when adjusting leap second state for an auxiliary timekeeper. This leads to a seqlock protocol violation where the timekeepers sequence ...
