CVE-2025-66769 2 Gonitro, Microsoft 2 Nitro Pdf Pro, Windows 2026-04-23 7.5 High
A NULL pointer dereference in Nitro PDF Pro for Windows v14.41.1.4 allows attackers to cause a Denial of Service (DoS) via a crafted XFA packet.
CVE-2026-31437 1 Linux 1 Linux Kernel 2026-04-23 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: netfs: Fix NULL pointer dereference in netfs_unbuffered_write() on retry When a write subrequest is marked NETFS_SREQ_NEED_RETRY, the retry path in netfs_unbuffered_write() unconditionally calls stream->prepare_write() without checking if it is NULL. Filesystems such as 9P do not set the prepare_write operation, so stream->prepare_write remains NULL. When get_user_pages() fails with -EFAULT and the subrequest is flagged for retry, this results in a NULL pointer dereference at fs/netfs/direct_write.c:189. Fix this by mirroring the pattern already used in write_retry.c: if stream->prepare_write is NULL, skip renegotiation and directly reissue the subrequest via netfs_reissue_write(), which handles iterator reset, IN_PROGRESS flag, stats update and reissue internally.
