CVE-2025-38577

CVE-2025-38577 affects the f2fs component of the Linux kernel. A use-after-free in the f2fs inode handling path leads to a KASAN failure observed during inode writeback (f2fs_update_inode/page, f2fs_write_inode) and can trigger a crash when the kernel attempts to delete a list entry in __list_del...

CVE-2025-38571

CVE-2025-38571 is a Linux kernel vulnerability affecting sunrpc/NFS over TLS. The issue arises from the client-side handling of TLS alerts in tls_alert_recv, caused by an assumption that the msghdr iterator’s kvec contains valid data. The patch reworks how control messages are set up and used by ...

CVE-2025-38567

The CVE-2025-38567 vulnerability affects the Linux kernel NFS server (nfsd) where racing calls to nfsd_open_local_fh() can cause an extra reference to the net to be leaked if both calls succeed in nfsd_file_acquire_local(). One instance will fail to store the file reference yet keep the extra net...

CVE-2025-38566

CVE-2025-38566 concerns the Linux kernel where the NFS over TLS path could mishandle TLS alerts in tls_alert_recv() due to how the kTLS control messages and data are split between the control buffer and the payload. The fix reworks how sock_recvmsg() sets up control messages so that, if a TLS con...
