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.

CVE-2026-23280 [HIGH] CWE-190 kernel: accel/amdxdna: Prevent ubuf size overflow
kernel: accel/amdxdna: Prevent ubuf size overflow
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.
A flaw was found in the Linux kernel's accel/amdxdna component. The calculation for the ubuf size may overflow, leading to an undersized memory allocation. This can result in memory corruption, potentially allowing an attacker to cause a denial of service or execute arbitrary code.
