| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nspi: spi-mem: Add fix to avoid divide error\n\nFor some SPI flash memory operations, dummy bytes are not mandatory. For\nexample, in Winbond SPINAND flash memory devices, the `write_cache` and\n`update_cache` operation variants have zero dummy bytes. Calculating the\nduration for SPI memory operations with zero dummy bytes causes\na divide error when `ncycles` is calculated in the\nspi_mem_calc_op_duration().\n\nAdd changes to skip the 'ncylcles' calculation for zero dummy bytes.\n\nFollowing divide error is fixed by this change:\n\n Oops: divide error: 0000 [#1] PREEMPT SMP NOPTI\n...\n\n ? do_trap+0xdb/0x100\n ? do_error_trap+0x75/0xb0\n ? spi_mem_calc_op_duration+0x56/0xb0\n ? exc_divide_error+0x3b/0x70\n ? spi_mem_calc_op_duration+0x56/0xb0\n ? asm_exc_divide_error+0x1b/0x20\n ? spi_mem_calc_op_duration+0x56/0xb0\n ? spinand_select_op_variant+0xee/0x190 [spinand]\n spinand_match_and_init+0x13e/0x1a0 [spinand]\n spinand_manufacturer_match+0x6e/0xa0 [spinand]\n spinand_probe+0x357/0x7f0 [spinand]\n ? kernfs_activate+0x87/0xd0\n spi_mem_probe+0x7a/0xb0\n spi_probe+0x7d/0x130" |
