Go ahead and remove the\nsun8i-ss support which is one of the only remaining ones.\n\nAs usual for crypto_rng, this driver was also buggy: its ->generate()\nfunction had a use-after-free vulnerability due to using\nwait_for_completion_interruptible_timeout() without handling shutting\ndown the DMA operation if a signal is sent.  Also, it had a buffer\noverread bug in the line 'memcpy(ctx->seed, d + dlen, ctx->slen);'.\nThere's no point in fixing these bugs separately only to remove the code\nanyway, so this commit is marked with Fixes and Cc stable.","published":"2026-09-04T16:18:12.000Z","lastModified":"2026-10-19T09:17:19.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00177,"percentile":0.07142,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
