CVE-2025-68304

CVE-2025-68304 concerns the Linux kernel Bluetooth path. The issue occurs in the RX path of HCI protocol handling where the hci_conn object may be concurrently modified/deleted while still being looked up, enabling a use-after-free in certain code paths. The bug was addressed by moving the lookup...

CVE-2025-68304 Bluetooth: hci_core: lookup hci_conn on RX path on protocol side

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicore: lookup hciconn on RX path on protocol side The hdev lock/lookup/unlock/use pattern in the packet RX path doesn't ensure hciconn is not concurrently modified/deleted. This locking appears to be leftover from...

CVE-2025-68302

CVE-2025-68302 concerns the Linux kernel driver net/sxgbe (sxgbe_main.c). The issue is a potential NULL dereference in sxgbe_rx() when skb is NULL, where an error is printed and skb is dereferenced on the next line. The fix adds a break after the error to switch to sxgbe_rx_refill(), mirroring th...
