Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: tracing/dma: CapDMAmapsg tracepoint arrays to prevent buffer overflows. The dmamapsg tracepoint can cause a PERF buffer overflow when tracing large scatter-gather lists. When devices like virtio-gpu create large DRM buffers, the...

CVE-2026-45908

A flaw was found in the Linux kernel's accel/amdxdna component. The amdxdnaubufmap function allocates memory for scatter-gather SG and internal SG table structures. However, it fails to free this allocated memory if subsequent operations, such as sgalloctablefrompages or dmamapsgtable, encounter ...
