Summary
Security update for the Linux Kernel
Details

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 rdevattrshow (bsc#1056134, bsc#1180963).
