Key Details

Affected Products, Subsystems & Sectors

What to Know

In the Linux kernel, the following vulnerability has been resolved:

xfs: initialise error in xfs_defer_finish_one()

xfs_defer_finish_one() declares error without an initialiser and only

assigns it inside the loop over dfp->dfp_work. When that list is empty

the loop body never runs, control falls through to the "Done with the

dfp, free it" path, and the function returns an indeterminate value.

An item-less pending item reaches this through xfs_defer_add_barrier(),

which xfs_reap_ag_blocks() uses on any CONFIG_XFS_ONLINE_REPAIR kernel.

xfs_defer_finish_noroll() treats any non-EAGAIN return as fatal, so a

non-zero stack value turns a successful barrier into a

SHUTDOWN_CORRUPT_INCORE in the middle of a repair. Zero is the correct

result: reaching the free path means the item loop drained without a

non-zero error. (NVD)
