CVE-2022-50296

CVE-2022-50296 affects the Linux kernel where cpu_max_bits_warn() would warn when CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are enabled while displaying /proc/cpuinfo. The root cause is using NR_CPUS to iterate CPUs instead of the runtime limit nr_cpu_ids, which leads to a runtime war...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from traversing the CPU using NRCPUS instead of nrcpuids under the CONFIGCPUMASKOFFSTACK and CONFIGDEBUGPERCPUMAP...

AZL-67166 CVE-2025-39749 affecting package kernel for versions less than 6.6.104.2-1

In the Linux kernel, the following vulnerability has been resolved: rcu: Protect -deferqsiwpending from data race On kernels built with CONFIGIRQWORK=y, when rcureadunlock is invoked within an interrupts-disabled region of code 1, it will invoke rcureadunlockspecial, which uses an irq-work handle...

CVE-2025-39749

The CVE-2025-39749 issue is in the Linux kernel’s RCU read-side handling: when IRQ work is used (CONFIG_IRQ_WORK=y) and rcu_read_unlock() runs in an interrupts-disabled region, irq-work can interrupt rcu_read_unlock_special(), creating a data race on the per-CPU defer_qs_iw_pending field. The fix...
