  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nmm: vmalloc: check if a hash-index is in cpu_possible_mask\nThe problem is that there are systems where cpu_possible_mask has gaps\nbetween set CPUs, for example SPARC.  In this scenario addr_to_vb_xa()\nhash function can return an index which accesses to not-possible and not\nsetup CPU area using per_cpu() macro.  This results in an oops on SPARC.\nA per-cpu vmap_block_queue is also used as hash table, incorrectly\nassuming the cpu_possible_mask has no gaps.  Fix it by adjusting an index\nto a next possible CPU.", "A vulnerability was found in the Linux kernel that involves improper handling of per-CPU data in systems where cpu_possible_mask has gaps between CPUs. This can lead to an index which accesses non-existent or unset CPU areas and potentially causes kernel crashes." ],
