ufs: core: Fix heap corruption due to out of bounds write 2026-04-22T08:06:01+00:00 Marek Vasut marek.vasut+renesas@mailbox.org 2026-03-29T23:11:36+00:00 c7ebdb9871dfd6e170a6dfeee39be234c37a4b53 The ufshcd_read_string_desc() can perform out of bounds write and corrupt heap in case the input utf-16 string contains code points which convert to anything more than plain 7-bit ASCII string. This occurs because utf16_to_utf8(dst, src, size) in U-Boot behaves differently than Linux utf16s_to_utf8s(..., maxlen), but the porting process did not take that into consideration. The U-Boot variant of the function converts up to $size utf-16 fixed-length 16-bit input characters into as many 1..4 Byte long variable-length utf-8 output characters. That means for 16 Byte input, the output can be up to 64 Bytes long. The Linux variant converts up utf-16 input into up to $maxlen Bytes worth of utf-8 output, but stops at the $maxlen limit. That means for 16 Byte input with maxlen=32, the processing will stop after writing 32 output Bytes. In case of U-Boot, use of utf16_to_utf8() leads to potential corruption of data past the $size Bytes and therefore corruption of surrounding content on the heap. The fix is as simple, allocate buffer that is sufficient to fit the utf-8 string. The rest of the code in ufshcd_read_string_desc() does correctly limit the buffer to fit into the DMA descriptor afterward.
