In the Linux kernel, the following vulnerability has been resolved:
erofs: fix out-of-bound access when zerofsgbuf_growsize() partially fails
If zerofsgbuf_growsize() partially fails on a global buffer due to memory allocation failure or fault injection (as reported by syzbot [1]), new pages need to be freed by comparing to the existing pages to avoid memory leaks.
However, the old gbuf->pages[] array may not be large enough, which can lead to null-ptr-deref or out-of-bound access.
Fix this by checking against gbuf->nrpages in advance.
