CVE-2026-45950

What it is

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.
