Overview
CVE-2026-23038 is a known-severity vulnerability. It was published on January 31, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
pnfs/flexfiles: Fix memory leak in nfs4_ff_alloc_deviceid_node()
In nfs4_ff_alloc_deviceid_node(), if the allocation for ds_versions fails,
the function jumps to the out_scratch label without freeing the already
allocated dsaddrs list, leading to a memory leak.
Fix this by jumping to the out_err_drain_dsaddrs label, which properly
frees the dsaddrs list before cleaning up other resources.
