CVE-2019-11811 kernel: use-after-free in drivers/char/ipmi/ipmi_si_intf.c, ipmi_si_mem_io.c, ipmi_si_port_io.c
A flaw was found in the Linux kernels implementation of IPMI (remote baseband access) where an attacker with local access to read /proc/ioports may be able to create a use-after-free condition when the kernel module is unloaded. The use after-free condition may result in privilege escalation. Investigation is ongoing.
