Description:
A security issue and a vulnerability have been reported in the Linux Kernel, which can be exploited by malicious, local users to disclose potentially sensitive information, cause a DoS (Denial of Service), and potentially gain escalated privileges.
1) A deadlock within the "unix_stream_connect()" function in net/unix/af_unix.c can be exploited to cause a DoS by performing certain socket operations.
2) The "tcf_fill_node()" function in net/sched/cls_api.c does not properly clear the "tcm__pad2" structure member before returning it to userspace, which can be exploited to disclose kernel memory.
3) The "get_instantiation_keyring()" function in security/keys/keyctl.c does not properly increase the reference counter, which can be exploited to cause a crash or potentially gain escalated privileges.
