    dlm: fix plock invalid read

    In the Linux kernel, the following vulnerability has been resolved: dlm: fix plock invalid read This patch fixes an invalid read showed by KASAN. A unlock will allocate a "struct plock_op" and a followed send_op() will append it to a global send_list data structure. In some cases a followed dev_read() moves it to recv_list and dev_write() will cast it to "struct plock_xop" and access fields which are only available in those structures. At this point an invalid read happens by accessing those fields. To fix this issue the "callback" field is moved to "struct plock_op" to indicate that a cast to "plock_xop" is allowed and does the additional

    RDMA/hfi1: Fix potential integer multiplication overflow errors

    In the Linux kernel, the following vulnerability has been resolved: RDMA/hfi1: Fix potential integer multiplication overflow errors When multiplying of different types, an overflow is possible even when storing the result in a larger type. This is because the conversion is done after the multiplication. So arithmetic overflow and thus in incorrect value is possible. Correct an instance of this in the inter packet delay calculation. Fix by ensuring one of the operands is u64 which will promote the other to u64 as well ensuring no overflow.

    tty: goldfish: Use tty_port_destroy() to destroy port

    In the Linux kernel, the following vulnerability has been resolved: tty: goldfish: Use tty_port_destroy() to destroy port In goldfish_tty_probe(), the port initialized through tty_port_init() should be destroyed in error paths.In goldfish_tty_remove(), qtty->port also should be destroyed or else might leak resources. Fix the above by calling tty_port_destroy().
