Security update for the Linux Kernel (Live Patch 30 for SLE 15 SP1)

This update for the Linux Kernel 4.12.14-150100_197_111 fixes several issues.

The following security issues were fixed:

  • CVE-2022-43945: Fixed a buffer overflow in the NFSD implementation (bsc#1205128).
  • CVE-2022-4378: Fixed stack overflow in __do_proc_dointvec (bsc#1206207).
  • CVE-2022-3586: Fixed use-after-free in socket buffer (SKB) that could allow a local unprivileged user to cause a denial of service (bsc#1204439).
  • CVE-2022-3545: Fixed a use-after-free in area_cache_get() of the file drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c (bsc#1204415).
  • CVE-2022-41218: Fixed a use-after-free caused by refcount races, affecting dvb_demux_open() and dvb_dmxdev_release() in drivers/media/dvb-core/dmxdev.c (bsc#1202960).

Описание

A flaw was found in the Linux kernel's networking code. A use-after-free was found in the way the sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed) into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of service.

Описание

A stack overflow flaw was found in the Linux kernel's SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system.

Описание

The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC message with garbage data is still correctly formed according to the specification and is passed forward to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the allocated buffer space. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
