Linux Distros Unpatched Vulnerability : CVE-2022-49690

high Nessus Plugin ID 226983

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- In the Linux kernel, the following vulnerability has been resolved: net/tls: fix tls_sk_proto_close executed repeatedly After setting the sock ktls, update ctx->sk_proto to sock->sk_prot by tls_update(), so now ctx->sk_proto->close is tls_sk_proto_close(). When close the sock, tls_sk_proto_close() is called for sock->sk_prot->close is tls_sk_proto_close(). But ctx->sk_proto->close() will be executed later in tls_sk_proto_close(). Thus tls_sk_proto_close() executed repeatedly occurred. That will trigger the following bug. ================================================================= KASAN: null-ptr-deref in range [0x0000000000000010-0x0000000000000017] RIP: 0010:tls_sk_proto_close+0xd8/0xaf0 net/tls/tls_main.c:306 Call Trace: <TASK> tls_sk_proto_close+0x356/0xaf0 net/tls/tls_main.c:329 inet_release+0x12e/0x280 net/ipv4/af_inet.c:428 __sock_release+0xcd/0x280 net/socket.c:650 sock_close+0x18/0x20 net/socket.c:1365 Updating a proto which is same with sock->sk_prot is incorrect. Add proto and sock->sk_prot equality check at the head of tls_update() to fix it. (CVE-2022-49690)

Note that Nessus relies on the presence of the package as reported by the vendor.
