The issue occurs when handling socket buffer (skb) operations during error conditions, where improper memory manageme [truncated]
A vulnerability in the Linux kernel's IPvlan network driver could allow a local, privileged attacker to cause a denial of service (DoS) condition. The flaw exists in the `ipvlan_process_v4_outbound` and `ipvlan_process_v6_outbound` functions, which improperly use `skb->sk` (socket buffer socket pointer) during packet processing. This can lead to a NULL pointer dereference or use-after-free condition, resu [truncated]
A vulnerability in the Linux kernel's Freescale QDMA engine driver (fsl-qdma) could cause System-on-Chip (SoC) hangs when performing 16-byte unaligned memory reads. The issue was resolved in the Linux kernel. Siemens has assessed this CVE as 'Misinformed' for its affected industrial networking products, indicating the vulnerability does not apply to these specific product configurations.
A race condition in the Linux kernel's block multi-queue (blk-mq) subsystem can cause I/O operations to hang indefinitely. The vulnerability stems from a synchronization issue in the sbitmap (sparse bitmap) wakeup mechanism used for managing I/O request tags. When the race condition triggers, pending I/O requests may never be processed, leading to system unavailability or degraded performance in storage-d [truncated]
This CVE addresses a vulnerability in the Linux kernel's io_uring subsystem related to AF_UNIX sockets. The fix disables the ability to send io_uring file descriptors over Unix domain sockets, which could potentially be exploited to manipulate or corrupt kernel memory structures. The vulnerability was resolved by preventing this specific capability in the kernel's networking code. Siemens has assessed thi [truncated]
A use-after-free vulnerability in the Linux kernel's Griffin PowerMate USB input driver (powermate) was resolved via a code fix. The flaw existed in the powermate_config_complete callback function. Siemens has assessed this CVE as not affecting its RUGGEDCOM RST2428P and SCALANCE X-family industrial networking products, reclassifying them from affected to known not affected in subsequent advisory revision [truncated]
CVE-2022-48829 is a Linux kernel NFSD issue in NFSv3 SETATTR and CREATE handling for large file sizes. The bug can corrupt or silently alter incoming size values when they exceed the signed 64-bit range, which is unexpected behavior for clients and can affect NFS server availability and correctness. NVD rates the issue as medium severity, with local, low-privilege conditions required.
CVE-2022-48828 is a Linux kernel NFSD bug where an NFS file-size value can be copied into a signed 64-bit iattr::ia_size field without first checking whether the unsigned value exceeds S64_MAX. The result is an underflow in nfsd_setattr(), with availability impact only per the CVSS vector. The NVD record and linked kernel patches describe the issue as fixed in the common setattr path used by NFSv3 and NFSv4 handling.
CVE-2022-48827 is a Linux kernel NFS server bug where a READ request near OFFSET_MAX can overflow internal offset handling, leading the server to return EINVAL and the client to retry indefinitely. The fix changes out-of-range READ behavior to complete as a short read with EOF and ensures wire offsets are converted safely to loff_t before kernel checks.
CVE-2021-47316 is a Linux kernel nfsd NULL dereference issue in the nfs3svc_encode_getaclres XDR encoder. The NVD record lists Linux kernel versions 5.13 through before 5.13.4 as affected. The supplied description says that in error cases the dentry may be NULL, and that the encoder previously performed extra checks before later simplification. The published CVSS vector indicates a local, low-privilege pa [truncated]
CVE-2023-0386 is a Linux kernel vulnerability described as an improper ownership management issue. CISA added it to the Known Exploited Vulnerabilities catalog on 2025-06-17, which means it is considered known to be exploited and should be prioritized for remediation. The supplied corpus does not include deeper technical detail, so this debrief stays at a high level and focuses on defensive response.
CVE-2024-26596 is a Linux kernel availability issue in DSA netdevice event handling. The vulnerability was published on 2024-02-23 and describes a case where code dereferenced netdev_priv() before confirming the device was actually a DSA user device. On netdevices with zero private data size, such as the dummy interface, this can produce an out-of-bounds read and a kernel oops during NETDEV_PRECHANGEUPPER [truncated]
