In the Linux kernel, the following vulnerability has been resolved:
usb: storage: sddr55: Reject out-of-bound new_pba
Discovered by Atuin - Automated Vulnerability Discovery Engine.
new_pba comes from the status packet returned after each write.
A bogus device could report values beyond the block count derived
from info->capacity, letting the driver walk off the end of
pba_to_lba[] and corrupt heap memory.
Reject PBAs that exceed the computed block count and fail the
transfer so we avoid touching out-of-range mapping entries.
