Description
In the Linux kernel, the following vulnerability has been resolved:
scsi: ses: Fix slab-out-of-bounds in ses_enclosure_data_process()
A fix for:
BUG: KASAN: slab-out-of-bounds in ses_enclosure_data_process+0x949/0xe30 [ses]
Read of size 1 at addr ffff88a1b043a451 by task systemd-udevd/3271
Checking after (and before in next loop) addl_desc_ptr[1] is sufficient, we
expect the size to be sanitized before first access to addl_desc_ptr[1].
Make sure we don't walk beyond end of page.
