Details

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.

Severity ?

5.5 (Medium)
