https://notcve.org/view.php?id=CVE-2025-37780
01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: isofs: Prevent the use of too small fid syzbot reported a slab-out-of-bounds Read in isofs_fh_to_parent. [1] The handle_bytes value passed in by the reproducing program is equal to 12. In handle_to_path(), only 12 bytes of memory are allocated for the structure file_handle->f_handle member, which causes an out-of-bounds access when accessing the member parent_block of the structure isofs_fid in isofs, because accessing parent_block requires... • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 •

CVE-2025-37778 – ksmbd: Fix dangling pointer in krb_authenticate
https://notcve.org/view.php?id=CVE-2025-37778
01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix dangling pointer in krb_authenticate krb_authenticate frees sess->user and does not set the pointer to NULL. It calls ksmbd_krb5_authenticate to reinitialise sess->user but that function may return without doing so. If that happens then smb2_sess_setup, which calls krb_authenticate, will be accessing free'd memory when it later uses sess->user. In the Linux kernel, the following vulnerability has been resolved: ksmbd: Fix danglin... • https://git.kernel.org/stable/c/d5b554bc8d554ed6ddf443d3db2fad9f665cec10 •

CVE-2025-37777 – ksmbd: fix use-after-free in __smb2_lease_break_noti()

If ksmbd connection is referenced when ksmbd server thread terminates, It will not be freed, but conn->tcp_transport is freed. __smb2_lease_break_noti can be performed asynchronously when the connection is disconnected. __smb2_lease_break_noti calls ksmbd_conn_write, which can cause use-after-free when conn->ksmbd_transport is already freed.
