Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mm: vmalloc: check if a hash-index is in cpu_possible_mask<br /> <br /> The problem is that there are systems where cpu_possible_mask has gaps<br /> between set CPUs, for example SPARC. In this scenario addr_to_vb_xa()<br /> hash function can return an index which accesses to not-possible and not<br /> setup CPU area using per_cpu() macro. This results in an oops on SPARC.<br /> <br /> A per-cpu vmap_block_queue is also used as hash table, incorrectly<br /> assuming the cpu_possible_mask has no gaps. Fix it by adjusting an index<br /> to a next possible CPU.
