1 high-severity fix in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Integer overflows in Triton block pointer calculation (using tl.make_block_ptr) can cause illegal memory accesses and system crashes when working with large tensors and long sequences. Casting sequence offsets to 64-bit integers prevents this index truncation.
Denial of Service: Triton convolution kernels are vulnerable to 32-bit integer overflows in their forward/backward passes during pointer arithmetic (such as indexing with cu_seqlens and i_n), leading to memory corruption.
Auth Bypass: Untrusted pull request filenames could lead to command injection inside the GitHub Actions runner execution environment via steps outputs. Upgrading tj-actions/changed-files mitigates this execution vector.
