Kernel Live Patch Security Notice LSN-0090-1

David Bouman discovered that the netfilter subsystem in the Linux kernel did not properly validate passed user register indices. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. David Bouman and Billy Jheng Bing Jhong discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Various other issues were also addressed.

Linux kernel vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 20.04 LTS
  • Ubuntu 18.04 LTS
  • Ubuntu 22.04 LTS

Summary

Several security issues were fixed in the kernel.

Software Description

  • linux - Linux kernel
  • linux-aws - Linux kernel for Amazon Web Services (AWS) systems
  • linux-azure - Linux kernel for Microsoft Azure Cloud systems
  • linux-gcp - Linux kernel for Google Cloud Platform (GCP) systems
  • linux-gke - Linux kernel for Google Container Engine (GKE) systems
  • linux-gkeop - Linux kernel for Google Container Engine (GKE) systems
  • linux-ibm - Linux kernel for IBM cloud systems

Details

David Bouman discovered that the netfilter subsystem in the Linux kernel
did not properly validate passed user register indices. A local attacker
could use this to cause a denial of service or possibly execute
arbitrary code. (CVE-2022-1015)

David Bouman and Billy Jheng Bing Jhong discovered that a race condition
existed in the io_uring subsystem in the Linux kernel, leading to a use-
after-free vulnerability. A local attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-2602)

Sönke Huster discovered that an integer overflow vulnerability existed
in the WiFi driver stack in the Linux kernel, leading to a buffer
overflow. A physically proximate attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-41674)

Sönke Huster discovered that the WiFi driver stack in the Linux kernel did
not properly perform reference counting in some situations, leading to a
use-after-free vulnerability. A physically proximate attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2022-42720)

Sönke Huster discovered that the WiFi driver stack in the Linux kernel did
not properly handle BSSID/SSID lists in some situations. A physically
proximate attacker could use this to cause a denial of service (infinite
loop). (CVE-2022-42721)

Sönke Huster discovered that the WiFi driver stack in the Linux kernel
contained a NULL pointer dereference vulnerability in certain situations. A
physically proximate attacker could use this to cause a denial of service
(system crash). (CVE-2022-42722)

CVE-2022-42721

A list management bug in BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to corrupt a linked list and, in turn, potentially execute code.

CVE-2022-42722: Invalid Bug ID

In the Linux kernel 5.8 through 5.19.14, local attackers able to inject WLAN frames into the mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon protection of P2P devices.

CVE-2022-42720: Invalid Bug ID

Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 through 5.19.x before 5.19.16 could be used by local attackers (able to inject WLAN frames) to trigger use-after-free conditions to potentially execute code.

CVE-2022-41674: git/torvalds/linux.git - Linux kernel source tree

An issue was discovered in the Linux kernel before 5.19.16. Attackers able to inject WLAN frames could cause a buffer overflow in the ieee80211_bss_info_update function in net/mac80211/scan.c.

CVE-2022-1016: CVE-2022-1015,CVE-2022-1016 in nf_tables cause privilege escalation, information leak

A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker.
