Description:

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

The following security bugs were fixed:

  • CVE-2020-26555: Fixed Bluetooth legacy BR/EDR PIN code pairing in Bluetooth Core Specification 1.0B that may permit an unauthenticated nearby device to spoof the BD_ADDR of the peer device to complete pairing without knowledge of the PIN (bsc#1179610 bsc#1215237).
  • CVE-2022-45887: Fixed a memory leak in ttusb_dec.c caused by the lack of a dvb_frontend_detach call (bsc#1205762).
  • CVE-2023-1206: Fixed a hash collision flaw in the IPv6 connection lookup table which could be exploited by network adjacent attackers, increasing CPU usage by 95% (bsc#1212703).
  • CVE-2023-31085: Fixed a divide-by-zero error in do_div(sz,mtd->erasesize) that could cause a local DoS (bsc#1210778).
  • CVE-2023-3111: Fixed a use-after-free vulnerability in prepare_to_relocate in fs/btrfs/relocation.c (bsc#1212051).
  • CVE-2023-39189: Fixed a flaw in the Netfilter subsystem that could allow a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure (bsc#1216046).
  • CVE-2023-39192: Fixed an out of bounds read in the netfilter (bsc#1215858).
  • CVE-2023-39193: Fixed an out of bounds read in the xtables subsystem (bsc#1215860).
  • CVE-2023-39197: Fixed a out-of-bounds read in nf_conntrack_dccp_packet() (bsc#1216976).
  • CVE-2023-45863: Fixed a out-of-bounds write in fill_kobj_path() (bsc#1216058).
  • CVE-2023-51779: Fixed a use-after-free because of a bt_sock_ioctl race condition in bt_sock_recvmsg (bsc#1218559).
  • CVE-2023-6606: Fixed an out of bounds read in the SMB client when receiving a malformed length from a server (bsc#1217947).
  • CVE-2023-6932: Fixed a use-after-free vulnerability in the Linux kernel's ipv4: igmp component that could lead to local privilege escalation (bsc#1218253).
