CVE-2024-41094

The CVE-2024-41094 issue affects the Linux kernel DRM fbdev-dma path. The root cause is unsafe handling of memory for the framebuffer when smem_start is exported via module options, which can break on systems where DMA memory is backed by vmalloc and may trigger non-linear virt_to_phys address ch...

DEBIAN-CVE-2024-41032

In the Linux kernel, the following vulnerability has been resolved: mm: vmalloc: check if a hash-index is in cpupossiblemask The problem is that there are systems where cpupossiblemask has gaps between set CPUs, for example SPARC. In this scenario addrtovbxa hash function can return an index whic...

CVE-2024-41032

CVE-2024-41032: Linux kernel vulnerability in vmalloc hash indexing. Systems where cpu_possible_mask has gaps (e.g., SPARC) could cause addr_to_vb_xa() to hash to a non-existent CPU, accessing an uninitialized per-CPU area and triggering an oops. The per-CPU vmap_block_queue also treated cpu_poss...
