title: Red Hat Security Advisory: kernel security and bug fix update
description: kernel: double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c kernel: denial of service via ioctl call in network tun handling kernel: usb: missing size check in the __usb_get_extra_descriptor() leading to DoS kernel: perf_event_open() and execve() race in setuid programs allows a data leak kernel: brcmfmac frame validation bypass Kernel: net: using kernel space address bits to derive IP ID may potentially break KASLR kernel: unchecked kstrdup of fwstr in drm_load_edid_firmware leads to denial of service kernel: use-after-free in arch/x86/lib/insn-eval.c kernel: integer overflow and OOB read in drivers/block/floppy.c kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c leads to denial of service kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause kernel panic
