- Summary
- [none]
- Details
-
An issue was discovered in fs/xfs/xfsicache.c in the Linux kernel through 4.17.3. There is a NULL pointer dereference and panic in lookupslow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occurs because of a lack of proper validation that cached inodes are free during allocation.
