An update that solves five vulnerabilities and has 18 security fixes can now be installed.

Description:

The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

CVE-2021-22555: A heap out-of-bounds write was discovered in net/netfilter/x_tables.c (bnc#1188116).
CVE-2021-33909: Extremely large seq buffer allocations in seq_file could lead to buffer underruns and code execution (bsc#1188062).
CVE-2021-3609: A use-after-free in can/bcm could have led to privilege escalation (bsc#1187215).
CVE-2021-3612: An out-of-bounds memory write flaw was found in the joystick devices subsystem in the way the user calls ioctl JSIOCSBTNMAP. This flaw allowed a local user to crash the system or possibly escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability (bnc#1187585 ).
CVE-2021-35039: kernel/module.c mishandled Signature Verification, aka CID-0c18f29aae7c. 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 (bnc#1188080). NOTE that SUSE kernels are configured with CONFIG_MODULE_SIG=y, so are not affected.
