| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
nfs: Fix oops in nfs_netfs_init_request() when copying to cache
When netfslib wants to copy some data that has just been read on behalf of
nfs, it creates a new write request and calls nfs_netfs_init_request() to
initialise it, but with a NULL file pointer. This causes
nfs_file_open_context() to oops - however, we don't actually need the nfs
context as we're only going to write to the cache.
Fix this by just returning if we aren't given a file pointer and emit a
warning if the request was for something other than copy-to-cache.
Further, fix nfs_netfs_free_request() so that it doesn't try to free the
context if the pointer is NULL. |
