In the Linux kernel, the following vulnerability has been resolved:
ksmbd: preserve VFS inherited POSIX ACL mask
The VFS initializes a child's POSIX ACL from the parent's default ACL and
the requested creation mode. Do not mutate the parent ACL or overwrite the
child's VFS-computed access and default ACLs afterwards.
This preserves restrictive ACL_MASK entries and prevents SMB object creation
from widening effective permissions.
