  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ntls: Purge async_hold in tls_decrypt_async_wait()\n\nThe async_hold queue pins encrypted input skbs while\nthe AEAD engine references their scatterlist data. Once\ntls_decrypt_async_wait() returns, every AEAD operation\nhas completed and the engine no longer references those\nskbs, so they can be freed unconditionally.\n\nA subsequent patch adds batch async decryption to\ntls_sw_read_sock(), introducing a new call site that\nmust drain pending AEAD operations and release held\nskbs. Move __skb_queue_purge(\u0026ctx-\u003easync_hold) into\ntls_decrypt_async_wait() so the purge is centralized\nand every caller -- recvmsg's drain path, the -EBUSY\nfallback in tls_do_decryption(), and the new read_sock\nbatch path -- releases held skbs on synchronization\nwithout each site managing the purge independently.\n\nThis fixes a leak when tls_strp_msg_hold() fails part-way through,\nafter having added some cloned skbs to the async_hold\nqueue. tls_decrypt_sg() will then call tls_decrypt_async_wait() to\nprocess all pending decrypts, and drop back to synchronous mode, but\ntls_sw_recvmsg() only flushes the async_hold queue when one record has\nbeen processed in \"fully-async\" mode, which may not be the case here.\n\n[pabeni@redhat.com: added leak comment]",
