UBUNTU-CVE-2025-40245

In the Linux kernel, the following vulnerability has been resolved: nios2: ensure that memblock.currentlimit is set when setting pfn limits On nios2, with CONFIGFLATMEM set, the kernel relies on memblockgetcurrentlimit to determine the limits of memmap, in particular for maxlowpfn. Unfortunately,...

CVE-2025-40245

CVE-2025-40245 (Linux kernel, nios2) : On nios2 with CONFIG_FLATMEM, memblock.current_limit was not initialized early enough, so memblock_get_current_limit() could miscompute limits for mem_map, letting max_low_pfn exceed max_pfn and expanding DRAM access beyond valid range. This could cause kern...
