Issue Overview:
A use-after-free vulnerability was found in the Linux kernel’s ext4 filesystem in the way it handled the extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system crash or other undefined behaviors. (CVE-2023-2513)
qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write because lmax can exceed QFQ_MIN_LMAX. (CVE-2023-31436)
