CVE-2026-72010
A flaw was found in the Linux kernel's cgroup/cpuset component. A local user can exploit this by configuring a child cpuset without explicitly setting its memory nodes. When a CPU hotplug event occurs, a division-by-zero error is triggered during memory policy rebind, leading to a system crash...
CVE-2026-72212
A flaw was found in the Linux kernel's memory hotplug subsystem. An error in the memory cleanup process, specifically when memory is added and then an issue occurs during device creation, can lead to incorrect handling of memory pages. This vulnerability can result in memory corruption, potential...
CVE-2026-72172
A flaw was found in the Linux kernel. When Direct Access DAX memory is hotplugged, certain internal memory structures struct pages may not be fully initialized. This uninitialized state can lead to unexpected system behavior or crashes, potentially resulting in a denial of service...
CVE-2026-72067
A flaw was found in the Linux kernel's CPU hotplug mechanism. When the cpuhpinvokecallback function attempts to unwind previous operations after a failure, it can incorrectly reuse a return value. This issue allows a successful rollback to mask the original error, causing a failed CPU hotplug...
CVE-2026-72066
A flaw was found in the Linux kernel, specifically within the CPU hotplug feature. This vulnerability occurs because the statesshow function, which displays CPU hotplug state information, does not correctly limit the size of its output. An attacker could exploit this by providing a large number o...
CVE-2026-72016
A flaw was found in the Linux kernel's CPU hotplug mechanism on arm64 systems. When a system is booted with more maximum CPUs configured than are physically present, some CPUs are incorrectly marked as present but are not fully registered. This can lead to a kernel warning due to a null kobject...
CVE-2026-72172
In the Linux kernel, the following vulnerability has been resolved: mm/mminit: fix uninitialized struct pages for ZONEDEVICE If DAX memory is hotplugged into an unoccupied subsection of an early section, sectionactivate reuses the unoptimized boot memmap. However, compoundnrpages still assumes th...
CVE-2026-72067
In the Linux kernel, the following vulnerability has been resolved: cpu: hotplug: Preserve per instance callback errors cpuhpinvokecallback unwinds earlier callbacks for the same hotplug state when one instance fails. The rollback path currently reuses ret, so a successful rollback can hide the...
CVE-2026-72066
In the Linux kernel, the following vulnerability has been resolved: cpu: hotplug: Bound hotplug states sysfs output statesshow adds CPU hotplug state names into a single sysfs buffer using sprintf. With enough registered states, this can write past the end of the PAGESIZE buffer. Use sysfsemitat ...
