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-2026-17539

RTU500 (Hitachi Energy) is affected by a NULL pointer dereference in the last entry of the enhanced message queue, triggered under high-load scenarios such as sending GI (General Interrogation) requests at short intervals . This leads to a BCI_IEC104 fatal write error , causing connection interru...

CVE-2026-17539

RTU500 has a vulnerability, where high-load scenarios, such as sending GI requests at short intervals, may cause a NULL pointer dereference in the last entry of the enhanced message queue. This can cause a BCIIEC104 fatal write error, resulting in connection interruption and restart, and ultimate...

kernel: NFSv4/flexfiles: reject zero filehandle version count

A flaw was found in the Linux kernel's NFSv4 Network File System version 4 flexfiles component. This vulnerability occurs when the fflayoutalloclseg function processes a malformed flexfiles layout that specifies a zero filehandle version count. An attacker could exploit this by providing a...

kernel: NFSv4/pNFS: reject zero-length r_addr in nfs4_decode_mp_ds_addr

A flaw was found in the Linux kernel's NFSv4/pNFS implementation. The nfs4decodempdsaddr function, responsible for decoding network address information, does not properly handle zero-length raddr opaque data. A malicious or compromised metadata server can exploit this by providing a zero-length...
