Description: The SUSE Linux Enterprise 15 SP2 RT kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2022-0435: Fixed remote stack overflow in net/tipc module that validate domain record count on input (bsc#1195254). - CVE-2021-45095: Fixed refcount leak in pep_sock_accept in net/phonet/pep.c (bnc#1193867). - CVE-2022-22942: Fixed stale file descriptors on failed usercopy (bsc#1195065). - CVE-2021-22600: Fixed double free bug in packet_set_ring() in net/packet/af_packet.c that could have been exploited by a local user through crafted syscalls to escalate privileges or deny service (bnc#1195184). - CVE-2021-39657: Fixed out of bounds read due to a missing bounds check in ufshcd_eh_device_reset_handler of ufshcd.c. This could lead to local information disclosure with System execution privileges needed (bnc#1193864). - CVE-2021-39648: Fixed possible disclosure of kernel heap memory due to a race condition in gadget_dev_desc_UDC_show of configfs.c.
