PT-2024-10027

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to a race condition between the laundromat handling of revoked delegations and a client sending a free stateid operation in the Linux kernel's NFS server. This can...

All versions of Samba prior to 4.13.16 are vulnerable to a malicious client using an SMB1 or NFS race to allow a directory to be created in an area of the server file system not exported under the share definition. Note that SMB1 has to be enabled or the share also available via NFS in order for this attack to succeed.
