This update for the Linux Kernel 5.3.18-24_107 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-2022-3577: Fixed an out-of-bounds memory write in bigben_probe of drivers/hid/hid-bigbenff.c (bsc#1204470).
- 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).
- CVE-2022-2964: Fixed memory corruption issues in ax88179_178a devices (bsc#1202686).

Описание
A vulnerability has been found in Linux Kernel and classified as critical. Affected by this vulnerability is the function area_cache_get of the file drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c of the component IPsec. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The identifier VDB-211045 was assigned to this vulnerability.

Описание
An out-of-bounds memory write flaw was found in the Linux kernel's Kid-friendly Wired Controller driver. This flaw allows a local user to crash or potentially escalate their privileges on the system. It is in bigben_probe of drivers/hid/hid-bigbenff.c. The reason is incorrect assumption - bigben devices all have inputs. However, malicious devices can break this assumption, leaking to out-of-bound write.

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
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
