CVE-2026-80876 ring-buffer: Fix event length with forced 8-byte alignment

In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Fix event length with forced 8-byte alignment When RBFORCE8BYTEALIGNMENT is true, rbcalculateeventlength reserves the space of event-array0 for placing the data length and rbupdateevent stores the data length in...

CVE-2026-80876

CVE-2026-80876 affects the Linux kernel ring-buffer subsystem on architectures where RB_FORCE_8BYTE_ALIGNMENT is true (observed on riscv64 with CONFIG_HAVE_64BIT_ALIGNED_ACCESS=y). The root cause is a mismatch in length calculation: rb_calculate_event_length() unconditionally reserves sizeof(even...

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...
