fkie_cve-2025-37940

In the Linux kernel, the following vulnerability has been resolved:

ftrace: Add cond_resched() to ftrace_graph_set_hash()

When the kernel contains a large number of functions that can be traced, the loop in ftrace_graph_set_hash() may take a lot of time to execute. This may trigger the softlockup watchdog.

Add cond_resched() within the loop to allow the kernel to remain responsive even when processing a large number of functions.

This matches the cond_resched() that is used in other locations of the code that iterates over all functions that can be traced.

OESA-2025-1570 — kernel security update

Affected: openEuler:22.03-LTS-SP3: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

A double-free flaw was found in the Linux kernel’s NTFS3 subsystem in how a user triggers remount and umount simultaneously. This flaw allows a local user to crash or potentially escalate their privileges on the system.(CVE-2022-3238)

In the Linux kernel, the following vulnerability has been resolved:

perf/x86/amd: Fix crash due to race between amd_pmu_enable_all, perf NMI and throttling

amd_pmu_enable_all() does:

if (!test_bit(idx, cpuc->active_mask)) continue;

amd_pmu_enable_event(cpuc->events[idx]);

A perf NMI of another event can come between these two steps. Perf NMI handler internally disables and enables _all_ events, including the one which nmi-intercepted amd_pmu_enable_all() was in process of enabling. If that unintentionally enabled event has very low sampling period and causes immediate successive NMI, causing the event to be throttled, cpuc->events[idx] and cpuc->active_mask gets cleared by x86_pmu_stop(). This will result in amd_pmu_enable_event() getting called with event=NULL when amd_pmu_enable_all() resumes after handling the NMIs. This causes a kernel crash:
