CVE-2026-53114

CVE-2026-53114 affects the Linux kernel perf/amd/ibs component. The flaw arises from calling perf_allow_kernel() within the IBS NMI handler, which is unsafe and could be fatal. The fix caches the permission at event initialization by storing it in event->hw.flags and makes the NMI handler rely...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Tracing: Do not register unsupported perf events Synthetic events currently do not have a function to register perf events. This leads to calling the tracepoint register functions with a NULL function pointer, which triggers the...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

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. Check if the event is NULL in...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed the stackmap overflow check in bpfgetstackid Syzkaller reported a KASAN vulnerability related to out-of-bounds write operations in bpfgetstackid, when copying stack trace data. This issue occurs when the perf trace...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: perf: sched: Fixed a crash in perf when using the new isusertask helper. To obtain a user space stacktrace, the current task must be a user task that has executed in user space. It was previously possible to determine whether a...

PT-2026-52008

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the Linux kernel where the perf allow kernel function is called from the IBS NMI handler. Calling this function within the NMI Non-Maskable Interrupt context is unsafe...

CVE-2026-47141

A flaw was found in vm2, an open-source virtual machine VM sandbox for Node.js. Prior to version 3.11.4, NodeVM, a component of vm2, improperly exposed certain process-wide observability builtins, such as diagnosticschannel, asynchooks, and perfhooks. These builtins, which are designed for...

Astra Linux – Vulnerability in Linux

A flaw was discovered in the Linux kernel. A memory use-after-free vulnerability was identified in the perf subsystem, allowing a local attacker with permission to monitor perf events, thereby corrupting memory and potentially escalating privileges. The most significant threat of this vulnerabili...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: drm/i915/gem: The i915gemcontext link is now moved under ref protection. i915perf assumes that it can use the i915gemcontext reference to protect its i915-gem.contexts.list iteration. However, this requires that we do not remo...

CVE-2026-47141

vm2 is an open source vm/sandbox for Node.js. Prior to version 3.11.4, NodeVM exposes some process-wide observability builtins when they are allowed through require.builtin. The diagnosticschannel, asynchooks, and perfhooks builtins are not blocked by the dangerous builtin denylist. These modules...
