Problem solved by the commit
Fixed a critical integer overflow vulnerability in the AMD XRT kernel drivers when parsing XCLBIN headers.
Bug / issue (if any) fixed, which PR introduced the bug, how it was discovered
Vulnerability Type: CWE-190 (Integer Overflow) → CWE-122 (Heap Buffer Overflow)
How problem was solved, alternative solutions (if any) and why they were rejected
Added bounds validation for m_numSections before the vulnerable calculation
Risks (if any) associated the changes in the commit
None
What has been tested and how, request additional testing if necessary
Ran xrt validation test suite.
m_numSections = 0 → Should return -EINVAL
m_numSections > 0x10000 → Should return -EINVAL
Documentation impact (if any)
None
