The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - nvmem: zynqmpnvmem: Fix buffer size in DMA and memcpy Buffer size used in dma allocation and memcpy is wrong. It can lead to undersized DMA buffer access and...

CVE-2026-43044

A flaw was found in the Linux kernel's crypto: caam module. When processing HMAC Keyed-Hash Message Authentication Code keys longer than the block size, the memory allocated for the key copy was not correctly aligned for Direct Memory Access DMA operations. This oversight could lead to DMA...

CVE-2026-43044

In the Linux kernel, the following vulnerability has been resolved: crypto: caam - fix DMA corruption on long hmac keys When a key longer than block size is supplied, it is copied and then hashed into the real key. The memory allocated for the copy needs to be rounded to DMA cache alignment, as...

CVE-2026-43044

The CVE-2026-43044 issue affects the Linux kernel's crypto: caam module. When processing HMAC keys longer than the block size, the copied key’s memory was not properly aligned for DMA, risking corruption of adjacent memory. The vulnerability’s root cause was the allocation of a copy that relied o...
