UBUNTU-CVE-2024-56654

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcievent: Fix using rcureadunlock while iterating The usage of rcureadunlock while inside listforeachentryrcu is not safe since for the most part entries fetched this way shall be treated as rcudereference: Note that t...

CVE-2024-56654

CVE-2024-56654 affects the Linux kernel Bluetooth stack. The flaw arises from using rcu_read_(un)lock inside list_for_each_entry_rcu, which is unsafe because entries dereferenced under RCU must be obtained via rcu_dereference(). The advisory states this is not legal and describes a patch that fix...

CVE-2024-56653

CVE-2024-56653 is a Linux kernel vulnerability in the Bluetooth btmtk pathway that can cause a slab-use-after-free in btmtk_process_coredump when handling coredumps. The issue arises because hci_devcd_append may release an sk_buff, after which the code can still access the freed object; a KASAN r...

CVE-2024-56605

CVE-2024-56605 is a Linux kernel vulnerability in Bluetooth L2CAP handling. The issue arises when bt_sock_alloc() creates an sk object and attaches it to a sock; on error, l2cap_sock_alloc() frees the sk but leaves a dangling sk pointer attached to the sock, allowing a potential use-after-free in...
