Last modified

CVE-2026-98963 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: btrfs: always return -EIOCBQUEUED after btrfs_uring_read_extent_endio If all bios finish before btrfs_encoded_read_regular_fill_pages() returns, it calls btrfs_uring_read_extent_endio() and previously returned the I/O status. A negative errno then made btrfs_uring_read_extent() unlock and free while btrfs_uring_read_finished() did the same again. Return -EIOCBQUEUED so only the deferred path cleans up..
