Description OSIDB Bzimport 2026-03-25 11:04:08 UTC 
In the Linux kernel, the following vulnerability has been resolved:

accel/amdxdna: Prevent ubuf size overflow

The ubuf size calculation may overflow, resulting in an undersized
allocation and possible memory corruption.

Use check_add_overflow() helpers to validate the size calculation before
allocation.
