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.

Affected configurations

• linux linux kernel (>= 6.12.59 < 6.12.80) • linux linux kernel (>= 6.16.10 < 6.17) • linux linux kernel (>= 6.17.1 < 6.18.21) • linux linux kernel (>= 6.19 < 6.19.11) • linux linux kernel 6.17 • linux linux kernel 7.0
