The SUSE Linux Enterprise 12 SP2 kernel was updated.

The following security bugs were fixed:

• CVE-2022-28390: Fixed a double free in drivers/net/can/usb/ems_usb.c vulnerability in the Linux kernel (bnc#1198031).
• CVE-2022-28388: Fixed a double free in drivers/net/can/usb/usb_8dev.c vulnerability in the Linux kernel (bnc#1198032).
• CVE-2018-20784: Fixed a denial of service (infinite loop in update_blocked_averages) by mishandled leaf cfs_rq in kernel/sched/fair.c (bnc#1126703).
• CVE-2018-7755: Fixed an issue in the fd_locked_ioctl function in drivers/block/floppy.c. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR (bnc#1084513).
• CVE-2020-10769: Fixed a buffer over-read flaw in the IPsec Cryptographic algorithm's module. This flaw allowed a local attacker with user privileges to cause a denial of service. (bnc#1173265)
• CVE-2021-28688: Fixed XSA-365 that includes initialization of pointers such that subsequent cleanup code wouldn't use uninitialized or stale values. This initialization went too far and may under certain conditions also overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died, leaving around zombie domains (bnc#1183646).

• CVE-2021-28688: Fixed XSA-365 that includes initialization of pointers such that subsequent cleanup code wouldn't use uninitialized or stale values. This initialization went too far and may under certain conditions also overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking persistent grants.

An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR (bnc#1084513).
