title: Red Hat Security Advisory: kernel-alt security and bug fix update
description: kernel: out of bounds write in function i2c_smbus_xfer_emulated in drivers/i2c/i2c-core-smbus.c kernel: double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c kernel: out of bounds write in i2c driver leads to local escalation of privilege kernel: null pointer dereference in dlpar_parse_cc_property in arch/powerrc/platforms/pseries/dlpar.c causing denial of service kernel: denial of service in in xfs_setattr_nonsize in fs/xfs/xfs_iops.c kernel: mounting a crafted ext4 filesystem image, performing some operations, and unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c kernel: a malicious USB device in the drivers/input/ff-memless.c leads to use-after-free kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c kernel: out-of-bounds read in set_fdc in drivers/block/floppy.c Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause kernel panic
