In the Linux kernel, the following vulnerability has been resolved: dccp/tcp: Unhash sk from ehash for tb2 alloc failure after check_estalblished(). syzkaller reported a warning [0] in inet_csk_destroy_sock() with no repro. WARN_ON(inet_sk(sk)->inet_num && !inet_csk(sk)->icsk_bind_hash); However, the syzkaller's log hinted that connect() failed just before the warning due to FAULT_INJECTION. [1] When connect() is called for an unbound socket, we search for an available ephemeral port. If a bhash bucket exists for the port, we call __inet_check_established() or __inet6_check_established() to check if the bucket is reusable. If reusable, we add the socket into ehash and set inet_sk(sk)->inet_num. Later, we look up the corresponding bhash2 bucket and try to allocate it if it does not exist. Although it rarely occurs in real use, if the allocation fails, we must revert the changes by check_established(). Otherwise, an unconnected socket could illegally occupy an ehash entry. Note that we do not put tw back into ehash because sk might have already responded to a packet for tw and it would be better to free tw earlier under such memory presure.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (bookworm), these problems have been fixed in     version 6.1.85-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to     its security tracker page at:
