31 Mar 2023 — hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux kernel through 6.2.9 has a use-after-free (observed in hci_conn_hash_flush) because of calls to hci_dev_put and hci_conn_put. There is a double free that may lead to privilege escalation. A double-free vulnerability was found in the hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux Kernel. This issue may cause a denial of service or privilege escalation. • https://lore.kernel.org/lkml/20230309074645.74309-1-wzhmmmmm%40gmail.com • CWE-415: Double Free •

27 Mar 2023 — A flaw was found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user can trigger this with rds_message_put(). Type confusion leads to `struct rds_msg_zcopy_info *info` actually points to something else that is potentially controlled by local user. It is known how to trigger this, which causes an out of bounds access, and a lock corruption. • http://www.openwall.com/lists/oss-security/2023/11/05/1 • CWE-787: Out-of-bounds Write CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •

27 Mar 2023 — A double-free flaw was found in the Linux kernel’s TUN/TAP device driver functionality in how a user registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw allows a local user to crash or potentially escalate their privileges on the system. The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include a double free vulnerability. • https://packetstorm.news/files/id/171912 • CWE-415: Double Free CWE-460: Improper Cleanup on Thrown Exception CWE-824: Access of Uninitialized Pointer •
