CVE-2026-45908

A flaw was found in the Linux kernel's accel/amdxdna component. The `amdxdna_ubuf_map` 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 `sg_alloc_table_from_pages` or `dma_map_sgtable`, encounter an error. This memory leak can be triggered by a local attacker, potentially leading to system instability or a Denial of Service (DoS) due to excessive memory consumption.
