The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2021-3659: Fixed a NULL pointer dereference in llsec_key_alloc() in net/mac802154/llsec.c (bsc#1188876). - CVE-2021-21781: Fixed a information disclosure vulnerability in the ARM SIGPAGE (bsc#1188445). - CVE-2021-22543: Fixed improper handling of VM_IO|VM_PFNMAP vmas in KVM, which could bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allowed users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation (bsc#1186482). - CVE-2021-37576: Fixed an issue on the powerpc platform, where a KVM guest OS user could cause host OS memory corruption via rtas_args.nargs (bsc#1188838). - CVE-2021-3609: Fixed a potential local privilege escalation in the CAN BCM networking protocol (bsc#1187215). - CVE-2021-3612: Fixed an out-of-bounds memory write flaw in the joystick devices subsystem. This flaw allowed a local user to crash the system or possibly escalate their privileges on the system. (bsc#1187585) - CVE-2021-35039: Fixed mishandling of signature verification. Without CONFIG_MODULE_SIG, verification that a kernel module is signed, for loading via init_module, did not occur for a module.sig_enforce=1 command-line argument (bsc#1188080).
