CVE-2026-80730

CVE-2026-80730 affects the Linux kernel's ring-buffer subsystem. The root cause is in test_ringbuffer()'s out_free cleanup loop: the !rb_threads[cpu] check only catches NULL entries but misses entries holding an ERR_PTR . When kthread_run_on_cpu() fails, it stores ERR_PTR(-ENOMEM) or ERR_PTR(-EIN...

CVE-2026-74601

A flaw was found in the Linux kernel's ring-buffer component. A race condition exists within the ringbufferswapcpu function, where a committing counter can temporarily drop to zero during a write operation. This allows a buffer swap to occur while a write is still in progress, resulting in an...

CVE-2026-74634

A flaw was found in the Linux kernel's ring-buffer component. This vulnerability occurs when the system attempts to change the order of sub-buffers while resizing is disabled, leading to memory being freed prematurely. A local attacker could exploit this use-after-free condition to potentially...

CVE-2026-74602

A flaw was found in the Linux kernel's ring-buffer component. The rballocatecpubuffer function failed to initialize the bpage-order value, leaving it as zero. This uninitialized value is later used by freebufferpage when deallocating ring-buffers with sub-buffers larger than a page size. An...

Astra Linux – Vulnerabilities in Linux, Linux-5.15, Linux-5.10

In the Linux kernel, the following vulnerability has been resolved: Ring-Buffer: Sync-IRQ works before the buffer is destroyed. If something was written to the buffer just before its destruction, it may be possible—though not in a real system—to destroy the ringbuffer before the IRQ-related...
