- Summary
- CVE-2026-98090 affecting package kernel for versions less than 6.6.158.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
btrfs: restore active device pointers after failed sprout
btrfs_init_new_device() switches latest_dev and possibly s_bdev from the seed device to the new sprout device before creating the first writable chunks.
If chunk creation or the subsequent sprout setup fails, the error path releases the new device without switching those pointers back. btrfs_show_devname() can then dereference the freed latest_dev and crash.
Restore the active device pointers to the latest seed device before removing and releasing the failed sprout device.
