The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * kernel: size_t-to-int conversion vulnerability in the filesystem layer * kernel: use-after-free in net/bluetooth/hci_event.c when destroying an hci_chan * kernel: use-after-free in show_numa_stats function * kernel: mishandles invalid descriptors in drivers/media/usb/gspca/xirlink_cit.c * kernel: use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
