Description OSIDB Bzimport 2024-10-21 20:01:52 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ntfs3: Change to non-blocking allocation in ntfs_d_hash

d_hash is done while under "rcu-walk" and should not sleep.
__get_name() allocates using GFP_KERNEL, having the possibility
to sleep when under memory pressure. Change the allocation to
GFP_NOWAIT.
