"value": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: accel: bmc150: clamp the device-reported FIFO frame count\n\n__bmc150_accel_fifo_flush() copies the number of samples the device\nreports in its hardware FIFO into an on-stack buffer\n\n\tu16 buffer[BMC150_ACCEL_FIFO_LENGTH * 3];\n\nwhich is sized for at most BMC150_ACCEL_FIFO_LENGTH (32) samples. The\nframe count is read from the FIFO_STATUS register and only masked to its\n7 valid bits:\n\n\tcount = val & 0x7F;\n\nso it can be 0..127. The only other limit applied to it is the optional\ncaller-supplied sample budget:\n\n\tif (samples && count > samples)\n\t\tcount = samples;\n\nwhich does not constrain count on the flush-all path (samples == 0), and\nleaves it well above 32 whenever samples is larger. count samples are\nthen transferred into buffer[]:\n\n\tbmc150_accel_fifo_transfer(data, (u8 *)buffer, count);\n\nbmc150_accel_fifo_transfer() reads count * 6 bytes through regmap, so a\nmalfunctioning, malicious or counterfeit accelerometer (or an attacker\ntampering with the I2C/SPI bus) that reports up to 127 frames writes up\nto 762 bytes into the 192-byte buffer: a stack out-of-bounds write of up\nto 570 bytes that clobbers the stack canary, saved registers and the\nreturn address.\n\nClamp count to BMC150_ACCEL_FIFO_LENGTH, the number of samples buffer[]\nis sized for, before the transfer, mirroring the watermark clamp already\ndone in bmc150_accel_set_watermark(). A well-formed flush reports at most\nBMC150_ACCEL_FIFO_LENGTH frames, so legitimate devices are unaffected."
