CVE-2026-45950

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: starfive - Fix memory leak in starfive_aes_aead_do_one_req()
The starfive_aes_aead_do_one_req() function allocates rctx->adata with kzalloc() but fails to free it if sg_copy_to_buffer() or starfive_aes_hw_init() fails, which lead to memory leaks.
Since rctx->adata is unconditionally freed after the write_adata operations, ensure consistent cleanup by freeing the allocation in these earlier error paths as well.
Compile tested only. Issue found using a prototype static analysis tool and code review.
