  "title": "cpufreq: imx6q: fix out-of-bounds write when probed more than once",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  cpufreq: imx6q: fix out-of-bounds write when probed more than once  imx6_soc_volt is allocated fresh on every probe, sized to the number of ARM OPPs:  \timx6_soc_volt = devm_kcalloc(cpu_dev, num, sizeof(*imx6_soc_volt), \t\t\t\t     GFP_KERNEL);  but it is filled through soc_opp_count, which has static storage and is never reset. A second bind after an unbind keeps indexing from where the first one stopped, and writes past the end of the new array.  Unbinding and rebinding the driver on qemu\u0027s mcimx6ul-evk, under KASAN:    BUG: KASAN: slab-out-of-bounds in imx6q_cpufreq_probe\u002B0x3b0/0xa34   Write of size 4 at addr c5e90480 by task binder/73    imx6q_cpufreq_probe from platform_probe\u002B0x88/0xe4    platform_probe from really_probe\u002B0x108/0x384    bind_store from kernfs_fop_write_iter\u002B0x1b4/0x28c  The write lands one u32 past the end of the allocation.  soc_opp_count is only read a few lines below the loop that fills it, so it never needed static storage. Make it a local.",
