Security update for the Linux Kernel (Live Patch 2 for SLE 15 SP4)

This update for the Linux Kernel 5.14.21-150400_24_18 fixes several issues.

The following security issues were fixed:

  • CVE-2023-35788: Fixed an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets in fl_set_geneve_opt in net/sched/cls_flower.c (bsc#1212509).
  • CVE-2023-2235: Fixed an use-after-free in the Performance Events system can be exploited to achieve local privilege escalation (bsc#1210987).
  • CVE-2023-2002: Fixed a flaw that allowed an attacker to unauthorized execution of management commands, compromising the confidentiality, integrity, and availability of Bluetooth communication (bsc#1210566).

A vulnerability was found in the HCI sockets implementation due to a missing capability check in net/bluetooth/hci_sock.c in the Linux Kernel. This flaw allows an attacker to unauthorized execution of management commands, compromising the confidentiality, integrity, and availability of Bluetooth communication.

Описание

A use-after-free vulnerability in the Linux Kernel Performance Events system can be exploited to achieve local privilege escalation. The perf_group_detach function did not check the event's siblings' attach_state before calling add_event_to_groups(), but remove_on_exec made it possible to call list_del_event() on before detaching from their group, making it possible to use a dangling pointer causing a use-after-free vulnerability. We recommend upgrading past commit fd0815f632c24878e325821943edccc7fde947a2.

Описание

An issue was discovered in fl_set_geneve_opt in net/sched/cls_flower.c in the Linux kernel before 6.3.7. It allows an out-of-bounds write in the flower classifier code via TCA_FLOWER_KEY_ENC_OPTS_GENEVE packets. This may result in denial of service or privilege escalation.
