Security update for the Linux Kernel (Live Patch 34 for SLE 12 SP2)

This update for the Linux Kernel 4.4.121-92_129 fixes several issues.

The following security issues were fixed:

  • CVE-2020-12653: Fixed a buffer overflow in mwifiex_cmd_append_vsie_tlv() which could have allowed local users to gain privileges or cause a denial of service (bsc#1171254).
  • CVE-2020-12654: Fixed a heap-based buffer overflow in mwifiex_ret_wmm_get_status() which could have been triggered by a remote AP to trigger (bsc#1171252).
  • CVE-2020-1749: Fixed an improper implementation in some IPsec protocols where the data were sent unencrypted allowing an attacker to read them (bsc#1165631).

Описание

An issue was found in Linux kernel before 5.5.4. The mwifiex_cmd_append_vsie_tlv() function in drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea.

Описание

A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality.
