SUSE CVE-2026-46029
In the Linux kernel, the following vulnerability has been resolved: mm/slab: return NULL early from kmallocnolock in NMI on UP On UP kernels !CONFIGSMP, spintrylock is a no-op that unconditionally succeeds even when the lock is already held. As a result, kmallocnolock called from NMI context can...
SUSE CVE-2026-46035
In the Linux kernel, the following vulnerability has been resolved: mm/pagealloc: return NULL early from allocfrozenpagesnolock in NMI on UP On UP kernels !CONFIGSMP, spintrylock is a no-op that unconditionally succeeds even when the lock is already held. As a result, allocfrozenpagesnolock calle...
CVE-2026-46029
A flaw was found in the Linux kernel. In uniprocessor UP kernel configurations, a race condition can occur within the slab memory allocator when kmallocnolock is invoked from a Non-Maskable Interrupt NMI context. This allows the allocator to attempt to acquire a spinlock that is already held,...
CVE-2026-46035
A flaw was found in the Linux kernel's memory management subsystem. On uniprocessor UP kernels, a Non-Maskable Interrupt NMI can cause the allocfrozenpagesnolock function to re-enter rmqueue and acquire a zone lock that is already held by an interrupted process. This can lead to corruption of the...

CVE-2026-46029
In the Linux kernel, CVE-2026-46029 describes a race within the slab allocator where kmalloc_nolock() called from NMI on uniprocessor (UP) configurations can re-enter the allocator and acquire n->list_lock that the interrupted context already holds, corrupting slab state and potentially causin...

Linux kernel 安全漏洞
The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the unconditional success of the spintrylock operation when calling kmallocnolock within the NMI contex...

In the Linux kernel, the following vulnerability has been resolved: perf/x86/amd: Check the event before enabling it to avoid a General Protection Fault GPF. On AMD machines, cpuc-eventsidx can become NULL due to a subtle race condition with NMI-throttle-x86pmustop. It is necessary to check if th...
