GHSA-hf6g-m6v3-8gj5

2026-10-03T09:31:58.631987+00:00

In the Linux kernel, the following vulnerability has been resolved:

nfs: fix possible null-ptr-deref when parsing param

According to commit "vfs: parse: deal with zero length string value", kernel will set the param->string to null pointer in vfs_parse_fs_string() if fs string has zero length.

Yet the problem is that, nfs_fs_context_parse_param() will dereferences the param->string, without checking whether it is a null pointer, which may trigger a null-ptr-deref bug.

This patch solves it by adding sanity check on param->string in nfs_fs_context_parse_param().
