https://notcve.org/view.php?id=CVE-2022-4744
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. • http://packetstormsecurity.com/files/171912/CentOS-Stream-9-Missing-Kernel-Security-Fix.html https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=158b515f703e https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://security.netapp.com/advisory/ntap-20230526-0009 https://access.redhat.com/security/cve/CVE-2022-4744 https://bugzilla.redhat.com/show_bug.cgi?id=2156322 • CWE-415: Double Free CWE-460: Improper Cleanup on Thrown Exception CWE-824: Access of Uninitialized Pointer •

https://notcve.org/view.php?id=CVE-2023-1078
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 https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=f753a68980cf4b59a80fe677619da2b1804f526d https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://security.netapp.com/advisory/ntap-20230505-0004 • CWE-787: Out-of-bounds Write CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2023-28866 – kernel: Bluetooth: HCI: global out-of-bounds access in net/bluetooth/hci_sync.c
https://notcve.org/view.php?id=CVE-2023-28866
In the Linux kernel through 6.2.8, net/bluetooth/hci_sync.c allows out-of-bounds access because amp_init1[] and amp_init2[] are supposed to have an intentionally invalid element, but do not. An out-of-bounds (OOB) memory access flaw was found in net/bluetooth/hci_sync.c due to a missing exit patch while in loop in amp_init1[] and amp_init2[]. This issue could allow an attacker to leak internal kernel information. • https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=95084403f8c070ccf5d7cbe72352519c1798a40a https://lore.kernel.org/lkml/20230321015018.1759683-1-iam%40sung-woo.kim https://patchwork.kernel.org/project/bluetooth/patch/20230322232543.3079578-1-luiz.dentz%40gmail.com https://access.redhat.com/security/cve/CVE-2023-28866 https://bugzilla.redhat.com/show_bug.cgi?id=2185519 • CWE-125: Out-of-bounds Read •
