CVE-2026-80538
Published Aug 26, 2026
Description
In the Linux kernel, the following vulnerability has been resolved: xfs: propagate errors from xfs_rtginode_load xfs_rtginode_ensure() treats every xfs_rtginode_load() error other than -ENOENT as success. This can leave the realtime group inode unset after an I/O, allocation, or corruption error. Growfs then continues as though the inode had been loaded. Only -ENOENT means that the inode needs to be created. Return all other errors to the growfs caller.
