CVE-2026-53114

A flaw was found in the Linux kernel's performance monitoring unit perf/amd/ibs. An issue exists where calling perfallowkernel from a Non-Maskable Interrupt NMI handler is unsafe. This could lead to a system crash, resulting in a Denial of Service DoS for the affected system...

CVE-2026-53106

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF local storage. This vulnerability can lead to a system deadlock when local storage is deleted within a Non-Maskable Interrupt NMI context. An attacker could potentially exploit this by triggering the deletion of BPF local storage...

CVE-2026-53162 memcg: use round-robin victim selection in refill_stock

In the Linux kernel, the following vulnerability has been resolved: memcg: use round-robin victim selection in refillstock Harry Yoo reported that getrandomu32below is not safe to call in the nmi context and memcg charge draining can happen in nmi context. More specifically getrandomu32below is...

CVE-2026-53162

Summary (CVE-2026-53162) : In the Linux kernel memcg subsystem, a non-NMI-safe path around random-number generation during NMI handling could corrupt the ChaCha batch state, enabling memcg charge draining. The fix replaces the get_random_u32_below() path with a per-CPU round-robin counter stored ...

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-2026-46035

CVE-2026-46035 affects the Linux kernel on UP (non-SMP) configurations and describes a vulnerability in mm/page_alloc. The issue arises because on UP, spin_trylock() is a no-op and may always succeed even if the lock is held, allowing alloc_frozen_pages_nolock() invoked from NMI to re-enter rmque...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, 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 within the NMI context on a single-process...

CVE-2026-43285

A flaw was found in the Linux kernel. An inconsistent lock state within the mm/slab subsystem, specifically when getfromanypartial is called in a Non-Maskable Interrupt NMI context, can lead to a deadlock. This vulnerability can result in a Denial of Service DoS for the affected system...

CVE-2026-43285

In the Linux kernel, the following vulnerability has been resolved: mm/slab: do not access current-memsallowedseq if !allowspin Lockdep complains when getfromanypartial is called in an NMI context, because current-memsallowedseq is seqcountspinlockt and not NMI-safe:...

CVE-2026-43285

Linux kernel mm/slab: do not access current->mems_allowed_seq if !allow_spin. The issue arises when get_from_any_partial() runs in NMI context, since seqcount_spinlock_t is not NMI-safe and can trigger a deadlock in the write/read sequence. Affected code path can lead to inconsistent lock stat...
