______________________________________________________________________________

   An update that solves 11 vulnerabilities and has two fixes
   is now available.

Description:

   The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2021-3483: Fixed a use-after-free in nosy.c (bsc#1184393).
   - CVE-2021-30002: Fixed a memory leak for large arguments in
     video_usercopy (bsc#1184120).
   - CVE-2021-29650: Fixed an issue where the netfilter subsystem allowed
     attackers to cause a denial of service (bsc#1184208).
   - CVE-2021-28972: Fixed a user-tolerable buffer overflow when writing a
     new device name to the driver from userspace, allowing userspace to
     write data to the kernel stack frame directly (bsc#1184198).
   - CVE-2021-28950: Fixed an infinite loop because a retry loop continually
     finds the same bad inode (bsc#1184194).
   - CVE-2021-27365: Fixed an issue where an unprivileged user can send a
     Netlink message that is associated with iSCSI, and has a length up to
     the maximum length of a Netlink message (bsc#1182715).
   - CVE-2021-27364: Fixed an issue where an attacker could craft Netlink
     messages (bsc#1182717).
   - CVE-2021-27363: Fixed a kernel pointer leak which could have been used
     to determine the address of the iscsi_transport structure (bsc#1182716).
   - CVE-2021-20261: Fixed a race condition in the implementation of the
     floppy disk drive controller driver software (bsc#1183400).
   - CVE-2020-36322: Fixed an issue in the FUSE filesystem implementation
     which could have caused a system crash (bsc#1184211).
   - CVE-2020-35519: Fixed an out-of-bounds memory access  was found in
     x25_bind (bsc#1183696).

   The following non-security bugs were fixed:

   - md: md.c: Return -ENODEV when mddev is NULL in rdev_attr_show
     (bsc#1056134, bsc#1180963).
