CVE-2024-36012 is a high-severity vulnerability affecting linux linux_kernel. It was published on May 23, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: msft: fix slab-use-after-free in msft_do_close()
Tying the msft->data lifetime to hdev by freeing it in
hci_release_dev() to fix the following case:
[use]
msft_do_close()
msft = hdev->msft_data;
if (!msft) ...(1) <- passed.
return;
mutex_lock(&msft->filter_lock); ...(4) <- used after freed.
[free]
msft_unregister()
msft = hdev->msft_data;
hdev->msft_data = NULL; ...(2)
kfree(msft); ...(3) <- msft is freed.
