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-2021-3347: A use-after-free was discovered in the PI futexes during fault handling, allowing local users to execute code in the kernel (bnc#1181349).
  • CVE-2020-0465: Fixed multiple missing bounds checks in hid-multitouch.c that could have led to local privilege escalation (bnc#1180029).
  • CVE-2020-25211: Fixed a flaw where a local attacker was able to inject conntrack netlink configuration that could cause a denial of service or trigger the use of incorrect protocol numbers in ctnetlinkparsetuple_filter (bnc#1176395).
  • CVE-2020-14390: Fixed an out-of-bounds memory write leading to memory corruption or a denial of service when changing screen size (bnc#1176235).
  • CVE-2020-25284: Fixed an incomplete permission checking for access to rbd devices, which could have been leveraged by local attackers to map or unmap rbd block devices (bsc#1176482).
  • CVE-2020-15436: Fixed a use after free vulnerability in fs/block_dev.c which could have allowed local users to gain privileges or cause a denial of service (bsc#1179141).
  • CVE-2020-14331: Fixed a missing check in vgacon scrollback handling (bsc#1174205).
  • CVE-2020-14353: Fixed an issue where keys - for keyctl prevent creating a different user's keyrings (bsc#1174993).
  • CVE-2020-14381: Fixed requeue paths such that filp was valid when dropping the references (bsc#1176011).
  • CVE-2020-27068: Fixed an out-of-bounds read due to a missing bounds check in the nl80211_policy policy of nl80211.c (bnc#1180086).
  • CVE-2020-27777: Fixed a privilege escalation in the Run-Time Abstraction Services (RTAS) interface, affecting guests running on top of PowerVM or KVM hypervisors (bnc#1179107).
  • CVE-2020-27786: Fixed an out-of-bounds write in the MIDI implementation (bnc#1179601).
  • CVE-2020-29660: Fixed a locking inconsistency in the tty subsystem that may have allowed a read-after-free attack against TIOCGSID (bnc#1179745).
  • CVE-2020-29661: Fixed a locking issue in the tty subsystem that allowed a use-after-free attack against TIOCSPGRP (bsc#1179745).
  • CVE-2020-28974: Fixed a slab-out-of-bounds read in fbcon which could have been used by local attackers to read privileged information or potentially crash the kernel (bsc#1178589).
  • CVE-2020-28915: Fixed a buffer over-read in the fbcon code which could have been used by local attackers to read kernel memory (bsc#1178886).
  • CVE-2020-25669: Fixed a use-after-free read in sunkbd_reinit() (bsc#1178182).
  • CVE-2020-25285: A race condition between hugetlb sysctl handlers in mm/hugetlb.c could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact (bnc#1176485 ).
  • CVE-2020-15437: Fixed a null pointer dereference which could have allowed local users to cause a denial of service (bsc#1179140).
  • CVE-2020-36158: Fixed a potential remote code execution in the Marvell mwifiex driver (bsc#1180559).
  • CVE-2020-11668: Fixed the mishandling of invalid descriptors in the Xirlink camera USB driver (bnc#1168952).
  • CVE-2020-25668: Fixed a use-after-free in confontop() (bsc#1178123).
  • CVE-2020-4788: Fixed an issue with IBM Power9 processors could have allowed a local user to obtain sensitive information from the data in the L1 cache under extenuating circumstances (bsc#1177666).
  • CVE-2020-0431: Fixed an out of bounds write due to a missing bounds check (bsc#1176722).
  • CVE-2020-0404: Fixed a linked list corruption due to an unusual root cause (bsc#1176423).
  • CVE-2019-20934: Fixed a use-after-free in shownumastats() because NUMA fault statistics were inappropriately freed (bsc#1179663).
  • CVE-2020-25656: Fixed a concurrency use-after-free in vtdokdgkb_ioctl (bnc#1177766).
  • CVE-2020-25643: Fixed a memory corruption and a read overflow which could have caused by improper input validation in the pppcpparse_cr function (bsc#1177206).
  • CVE-2019-16746: Fixed a buffer overflow in net/wireless/nl80211.c (bsc#1173659).

The following non-security bugs were fixed:

  • HID: Fix slab-out-of-bounds read in hidfieldextract (bsc#1180052).
  • cifs: bugfix for unreclaimed writeback pages in cifswritevrequeue() (bsc#1177906).
  • mm, vmstat: reduce zone->lock holding time by /proc/pagetypeinfo (bsc#1175691).
  • net/x25: fix a race in x25_bind() (bsc#1178590).
  • net/x25: prevent a couple of overflows (bsc#1178590).
