CVE-2026-31511 Details
Description
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: MGMT: Fix dangling pointer on mgmt_add_adv_patterns_monitor_complete This fixes the condition checking so mgmt_pending_valid is executed whenever status != -ECANCELED otherwise calling mgmt_pending_free(cmd) would kfree(cmd) without unlinking it from the list first, leaving a dangling pointer. Any subsequent list traversal (e.g., mgmt_pending_foreach during __mgmt_power_off, or another mgmt_pending_valid call) would dereference freed memory.
A vulnerability in the Linux kernel's Bluetooth management layer can lead to a use-after-free condition. This issue arises because the management command is freed without properly unlinking it from the list, creating a dangling pointer. Subsequent operations that traverse the list can then dereference this freed memory, potentially leading to undefined behavior.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed.
