CVE-2023-4273 – Kernel: exfat: stack overflow in exfat_get_uniname_from_ext_entry
https://notcve.org/view.php?id=CVE-2023-4273
09 Aug 2023 — A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation of the file name reconstruction function, which is responsible for reading file name entries from a directory index and merging file name parts belonging to one file into a single long file name. Since the file name characters are copied into a stack variable, a local privileged attacker could use this flaw to overflow the kernel stack.

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 •
