|

|

It's arguably a bug in Clang since we already use __builtin_assume_aligned()
|
||||
to tell the compiler that the pointer is properly aligned. But according to
|
||||
https://github.com/llvm/llvm-project/issues/69146 it seems like the Clang
|
||||
folks don't see an easy fix on their side and recommend to use a type
|
||||
declared with __attribute__((aligned(16))) to work around this problem.

hw/scsi/scsi-disk: Disallow block sizes smaller than 512 [CVE-2023-42467]
|
||||
|
||||
We are doing things like
|
||||
|
||||
nb_sectors /= (s->qdev.blocksize / BDRV_SECTOR_SIZE);
|
||||
|
||||
in the code here (e.g. in scsi_disk_emulate_mode_sense()), so if
|
||||
the blocksize is smaller than BDRV_SECTOR_SIZE (=512), this crashes
|
||||
with a division by 0 exception. Thus disallow block sizes of 256
|
||||
bytes to avoid this situation.
