Linux Distros Unpatched Vulnerability : CVE-2026-46077

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - crypto: atmel-tdes - fix DMA sync direction Before DMA output is consumed by the CPU, -dmaaddrout must be synced with dmasyncsingleforcpu instead of...

Securing High-Performance Data Transfers: Implementing AES Encryption in RDMA Systems

Remote Direct Memory Access RDMA is a key enabler of high-performance systems, offering low latency, high throughput, and reduced CPU overhead by allowing direct memory-to-memory transfers between machines. However, its design bypasses traditional CPU-mediated security mechanisms, introducing...

kernel: RDMA/umem: Fix double dma_buf_unpin in failure path

A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: drm/fbdev-dma: Added shadow buffering for deferred I/O. DMA areas are not necessarily backed by struct page, so we cannot rely on it for deferred I/O. Allocate a shadow buffer for drivers that require deferred I/O and use it a...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: lltemac: Ensure that the skb is freed when it is completely used. By using the TX BD to track the skb pointer, we can efficiently free the skb buffer after the frame has been transmitted. However, to avoid freeing the skb...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: avoid double-free when failing to DMA-map FW msg The semantics are that the caller of fbnicmbxmapmsg retains ownership of the message in case of an error. All existing callers properly free the allocated memory page...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: Ethernet: Aeroflex – Fix for a potential skb leak in grethinitrings The grethinitrings function does not free the newly allocated skb when dmamappingerror returns an error. Therefore, adding devkfreeskb is necessary to fix this...
