CVE-2026-98293 Bluetooth: ISO: Fix parent socket leak in iso_conn_ready()

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: Fix parent socket leak in isoconnready isogetsock returns the parent socket with a reference held, which is dropped by sockput once the child socket has been set up. The error path taken when isosockalloc fails on...

CVE-2026-98293

The Linux kernel contains a memory leak vulnerability within the Bluetooth ISO component. Specifically, the iso_conn_ready() function fails to properly release a reference to the parent socket when iso_sock_alloc() fails. While the reference is normally dropped by sock_put() upon successful child...
