In the Linux kernel, the following vulnerability has been resolved:
iio: accel: kxcjk-1013: Fix possible memory leak in probe and remove
When ACPI type is ACPI_SMO8500, the data->dready_trig will not be set, the
memory allocated by iio_triggered_buffer_setup() will not be freed, and cause
memory leak as follows:
unreferenced object 0xffff888009551400 (size 512):
comm “i2c-SMO8500-125”, pid 911, jiffies 4294911787 (age 83.852s)
hex dump (first 32 bytes):
02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 …
00 00 00 00 00 00 00 00 20 e2 e5 c0 ff ff ff ff … …
backtrace:
[<0000000041ce75ee>] kmem_cache_alloc_trace+0x16d/0x360
[<000000000aeb17b0>] iio_kfifo_allocate+0x41/0x130 [kfifo_buf]
[<000000004b40c1f5>] iio_triggered_buffer_setup_ext+0x2c/0x210 [industrialio_triggered_buffer]
[<000000004375b15f>] kxcjk1013_probe+0x10c3/0x1d81 [kxcjk_1013]
Fix it by remove data->dready_trig condition in probe and remove.
