accel/amdxdna: Fix out-of-bounds memset in command slot handling

Assigner: Linux
Reserved: 13.01.2026 Published: 25.03.2026 Updated: 25.03.2026

In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Fix out-of-bounds memset in command slot handling

The remaining space in a command slot may be smaller than the size of the command header. Clearing the command header with memset() before verifying the available slot space can result in an out-of-bounds write and memory corruption.

Fix this by moving the memset() call after the size validation.
