+Subject: [PATCH 2/3] net: crypto set sk to NULL when af_alg_release.
+
+KASAN has found use-after-free in sockfs_setattr.
+The existed commit 6d8c50dcb029 ("socket: close race condition between sock_close()
+and sockfs_setattr()") is to fix this simillar issue, but it seems to ignore
+that crypto module forgets to set the sk to NULL after af_alg_release.
+
+KASAN report details as below:
