In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_event: Fix handling of HCI_EV_IO_CAPA_REQUEST If we received HCI_EV_IO_CAPA_REQUEST while HCI_OP_READ_REMOTE_EXT_FEATURES is yet to be responded assume the remote does support SSP since otherwise this event shouldn't be generated.

CVSS: 5.5EPSS: 0%CPEs: 5EXPL: 0CVE-2024-27415 – netfilter: bridge: confirm multicast packets before passing them up the stack
https://notcve.org/view.php?id=CVE-2024-27415
In the Linux kernel, the following vulnerability has been resolved: netfilter: bridge: confirm multicast packets before passing them up the stack conntrack nf_confirm logic cannot handle cloned skbs referencing the same nf_conn entry, which will happen for multicast (broadcast) frames on bridges. Example: macvlan0 | br0 / \ ethX ethY ethX (or Y) receives a L2 multicast or broadcast packet containing an IP packet, flow is not yet in conntrack table. 1. skb passes through bridge and fake-ip (br_netfilter)Prerouting. -> skb->_nfct now references a unconfirmed entry 2. skb is broad/mcast packet. bridge now passes clones out on each bridge interface. 3. skb gets passed up the stack. 4. In macvlan case, macvlan driver retains clone(s) of the mcast skb and schedules a work queue to send them out on the lower devices. The clone skb->_nfct is not a copy, it is the same entry as the original skb. The macvlan rx handler then returns RX_HANDLER_PASS. 5. Normal conntrack hooks (in NF_INET_LOCAL_IN) confirm the orig skb. The Macvlan broadcast worker and normal confirm path will race. This race will not happen if step 2 already confirmed a clone. In that case later steps perform skb_clone() with skb->_nfct already confirmed (in hash table). • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 https://git.kernel.org/stable/c/7c3f28599652acf431a2211168de4a583f30b6d5 https://git.kernel.org/stable/c/2b1414d5e94e477edff1d2c79030f1d742625ea0 https://git.kernel.org/stable/c/80cd0487f630b5382734997c3e5e3003a77db315 https://git.kernel.org/stable/c/cb734975b0ffa688ff6cc0eed463865bf07b6c01 https://git.kernel.org/stable/c/62e7151ae3eb465e0ab52a20c941ff33bb6332e9 https://access.redhat.com/security/cve/CVE-2024-27415 https://bugzilla.redhat.com/show_bug.cgi?id=2281101 •

In the Linux kernel, the following vulnerability has been resolved: power: supply: bq27xxx-i2c: Do not free non existing IRQ The bq27xxx i2c-client may not have an IRQ, in which case client->irq will be 0. bq27xxx_battery_i2c_probe() already has an if (client->irq) check wrapping the request_threaded_irq(). But bq27xxx_battery_i2c_remove() unconditionally calls free_irq(client->irq) leading to: [ 190.310742] ------------[ cut here ]------------ [ 190.310843] Trying to free already-free IRQ 0 [ 190.310861] WARNING: CPU: 2 PID: 1304 at kernel/irq/manage.c:1893 free_irq+0x1b8/0x310 Followed by a backtrace when unbinding the driver.
