Details

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.
