CVE-2025-71130
In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Zero-initialize the eb.vma array in i915gemdoexecbuffer Initialize the eb.vma array with values of 0 when the eb structure is first set up. In particular, this sets the eb-vmai.vma pointers to NULL, simplifying...
CVE-2025-71139
CVE-2025-71139 – Linux kernel kexec CMA/IMA handling : The issue arises when the kexec target address is allocated in CMA space. The kernel’s kimage_map_segment() path assumes IND_SOURCE pages exist and maps them via vmap(), but CMA-based allocation bypasses IND_SOURCE, leading to a warning and i...
