CVE-2023-4194 – Kernel: tap: tap_open(): correctly initialize socket uid next fix of i_uid to current_fsuid
https://notcve.org/view.php?id=CVE-2023-4194
07 Aug 2023 — A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to bypass network filters and gain unauthorized access to some resources. The original patches fixing CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits - a096ccca6e50 ("tun: tun_chr_open(): correctly initialize socket uid"), - 66b2c338adce ("tap: tap_open(): correctly initialize socket uid"), pass "inode->i_uid" to sock_init_data_uid() as the last parameter and that t... • https://access.redhat.com/errata/RHSA-2023:6583 • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') CWE-863: Incorrect Authorization •

CVE-2023-4132 – Kernel: smsusb: use-after-free caused by do_submit_urb()
https://notcve.org/view.php?id=CVE-2023-4132
03 Aug 2023 — A use-after-free vulnerability was found in the siano smsusb module in the Linux kernel. The bug occurs during device initialization when the siano device is plugged in. This flaw allows a local user to crash the system, causing a denial of service condition. It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. • https://access.redhat.com/errata/RHSA-2023:6901 • CWE-416: Use After Free •

24 Jul 2023 — A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux Kernel. This issue may allow an attacker with local user access to cause a system crash or leak internal kernel information. It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

CVE-2023-3776 – Use-after-free in Linux kernel's net/sched: cls_fw component
https://notcve.org/view.php?id=CVE-2023-3776
21 Jul 2023 — A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b225... • http://packetstormsecurity.com/files/175072/Kernel-Live-Patch-Security-Notice-LSN-0098-1.html • CWE-416: Use After Free •
