Details

In the Linux kernel, the following vulnerability has been resolved:

iio: trigger: sysfs: fix possible memory leak in iiosysfstrig_init()

devsetname() allocates memory for name, it need be freed when deviceadd() fails, call putdevice() to give up the reference that hold in deviceinitialize(), so that it can be freed in kobjectcleanup() when the refcount hit to 0.

Fault injection test can trigger this:

unreferenced object 0xffff8e8340a7b4c0 (size 32): comm "modprobe", pid 243, jiffies 4294678145 (age 48.845s) hex dump (first 32 bytes): 69 69 6f 5f 73 79 73 66 73 5f 74 72 69 67 67 65 iiosysfstrigge 72 00 a7 40 83 8e ff ff 00 86 13 c4 f6 ee ff ff r..@............ backtrace: [<0000000074999de8>] _kmemcacheallocnode+0x1e9/0x360 [<00000000497fd30b>] _kmallocnodetrackcaller+0x44/0x1a0 [<000000003636c520>] kstrdup+0x2d/0x60 [<0000000032f84da2>] kobjectsetnamevargs+0x1e/0x90 [<0000000092efe493>] devset_name+0x4e/0x70
