Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: mm/slab: Early return of NULL from kmallocnolock in NMI on UP. On UP kernels with CONFIGSMP, spintrylock is a no-op that succeeds unconditionally even when the lock is already held. As a result, kmallocnolock, called from the NMI...
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...
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,...

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...
PT-2026-43896
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description On Uniprocessor UP kernels where CONFIG SMP is not enabled, the spin trylock function acts as a no-op and unconditionally succeeds. This allows kmalloc nolock called from a Non-Maskable...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: slab: fixed the context check for kmallocnolock in the PREEMPTRT kernel mode. In PREEMPTRT kernels, locallock acts as a sleeping lock. The current check in kmallocnolock only verifies that the context does not match NMI or hard I...
