CVE-2026-80927
A flaw was found in the Linux kernel. A race condition in the timekeeping subsystem, specifically within the doadjtimex function, can occur when the auxiliary clock is handled. This allows uninitialized stack data to be used in calculations and subsequently leaked to userspace, leading to...
CVE-2026-80927
In the Linux kernel, the following vulnerability has been resolved: timekeeping: Check the return value of tkgetauxts64 in doadjtimex If the auxiliary clock is disabled during tkgetauxts64 but is enabled before tks-clockvalid is checked, then uninitialized stackdata will be used in the calculatio...
CVE-2026-80927
CVE-2026-80927 affects the Linux kernel timekeeping subsystem. In __do_adjtimex(), a race condition allows the auxiliary clock to be disabled during tk_get_aux_ts64() and re-enabled before the tks->clock_valid check, causing uninitialized stack data to be used in calculations and indirectly le...

In the Linux kernel, the following vulnerability has been resolved: timekeeping: Check the return value of tk get aux ts64 in do adjtimex If the auxiliary clock is disabled during tk get aux ts64 but is enabled before tks-clock valid is checked, then uninitialized stackdata will be used in the...
CVE-2026-80724
A flaw was found in the Linux kernel's vmclock component. This vulnerability allows a guest operating system, through a userspace process, to change a shared memory page from read-only to writable. This occurs because the vmclockmiscdevmmap function fails to properly restrict permission upgrades...

CVE-2026-80724
CVE-2026-80724 affects the Linux kernel's ptp/vmclock driver. The root cause is that vmclock_miscdev_mmap() rejects writable mappings of the shared vmclock ABI page with -EROFS but leaves VM_MAYWRITE set, allowing a guest to map the page read-only and then upgrade it to writable via mprotect(). T...

CVE-2026-68092
The CVE-2026-68092 issue affects the Linux kernel where the time/jiffies clocksource is used before it is registered during early boot, leaving max_delta_raw at zero and halting time progress. This caused long boot delays (notably on XEN HVM in some cases). The documented fix initializes the jiff...
