Kernel version is 5.3.18-59.5.2.
The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
- CVE-2021-33200: Enforcing incorrect limits for pointer arithmetic
operations by the BPF verifier could be abused to perform out-of-bounds
reads and writes in kernel memory (bsc#1186484).
- CVE-2021-33034: Fixed a use-after-free when destroying an hci_chan. This
could lead to writing an arbitrary values. (bsc#1186111)
- CVE-2020-26139: Fixed a denial-of-service when an Access Point (AP)
forwards EAPOL frames to other clients even though the sender has not
yet successfully authenticated to the AP. (bnc#1186062)
- CVE-2021-23134: A Use After Free vulnerability in nfc sockets allowed
local attackers to elevate their privileges. (bnc#1186060)
- CVE-2021-3491: Fixed a potential heap overflow in mem_rw(). This
vulnerability is related to the PROVIDE_BUFFERS operation, which allowed
the MAX_RW_COUNT limit to be bypassed (bsc#1185642).
- CVE-2021-32399: Fixed a race condition when removing the HCI controller
(bnc#1184611).
- CVE-2020-24586: The 802.11 standard that underpins Wi-Fi Protected
Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't
require that received fragments be cleared from memory after
(re)connecting to a network. Under the right circumstances this can be
abused to inject arbitrary network packets and/or exfiltrate user data
(bnc#1185859).
- CVE-2020-24587: The 802.11 standard that underpins Wi-Fi Protected
Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't
require that all fragments of a frame are encrypted under the same key.
An adversary can abuse this to decrypt selected fragments when another
device sends fragmented frames and the WEP, CCMP, or GCMP encryption key
is periodically renewed (bnc#1185859 bnc#1185862).
- CVE-2020-24588: The 802.11 standard that underpins Wi-Fi Protected
Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't
require that the A-MSDU flag in the plaintext QoS header field is
authenticated. Against devices that support receiving non-SSP A-MSDU
frames (which is mandatory as part of 802.11n), an adversary can abuse
this to inject arbitrary network packets. (bnc#1185861)
- CVE-2020-26147: The WEP, WPA, WPA2, and WPA3 implementations reassemble
fragments, even though some of them were sent in plaintext. This
vulnerability can be abused to inject packets and/or exfiltrate selected
fragments when another device sends fragmented frames and the WEP, CCMP,
or GCMP data-confidentiality protocol is used (bnc#1185859).
- CVE-2020-26145: An issue was discovered with Samsung Galaxy S3 i9305
4.4.4 devices. The WEP, WPA, WPA2, and WPA3 implementations accept
second (or subsequent) broadcast fragments even when sent in plaintext
and process them as full unfragmented frames. An adversary can abuse
this to inject arbitrary network packets independent of the network
configuration. (bnc#1185860)
- CVE-2020-26141: An issue was discovered in the ALFA driver for AWUS036H,
where the Message Integrity Check (authenticity) of fragmented TKIP
frames was not verified. An adversary can abuse this to inject and
possibly decrypt packets in WPA or WPA2 networks that support the TKIP
data-confidentiality protocol. (bnc#1185987)
- CVE-2021-29650: Fixed an issue with the netfilter subsystem that allowed
attackers to cause a denial of service (panic) because
net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h lack a
full memory barrier upon the assignment of a new table value
(bnc#1184208).
- CVE-2021-29155: Fixed an issue that was discovered in
kernel/bpf/verifier.c that performs undesirable out-of-bounds
speculation on pointer arithmetic, leading to side-channel attacks that
defeat Spectre mitigations and obtain sensitive information from kernel
memory. Specifically, for sequences of pointer arithmetic operations,
the pointer modification performed by the first operation was not
correctly accounted for when restricting subsequent operations
(bnc#1184942).
- CVE-2021-3444: Fixed an issue with the bpf verifier which did not
properly handle mod32 destination register truncation when the source
register was known to be 0 leading to out of bounds read (bsc#1184170).
- CVE-2021-3428: Fixed an integer overflow in ext4_es_cache_extent
(bsc#1173485).
- CVE-2021-29647: Fixed an issue in qrtr_recvmsg which could have allowed
attackers to obtain sensitive information from kernel memory because of
a partially uninitialized data structure (bsc#1184192 ).
- CVE-2021-29265: Fixed an issue in usbip_sockfd_store which could have
allowed attackers to cause a denial of service due to race conditions
during an update of the local and shared status (bsc#1184167).
- CVE-2021-29264: Fixed an issue in the Freescale Gianfar Ethernet driver
which could have allowed attackers to cause a system crash due to a
calculation of negative fragment size (bsc#1184168).
- CVE-2021-28972: Fixed a user-tolerable buffer overflow when writing a
new device name to the driver from userspace, allowing userspace to
write data to the kernel stack frame directly (bsc#1184198).
- CVE-2021-28971: Fixed an issue in intel_pmu_drain_pebs_nhm which could
have caused a system crash because the PEBS status in a PEBS record was
mishandled (bsc#1184196 ).
- CVE-2021-28964: Fixed a race condition in get_old_root which could have
allowed attackers to cause a denial of service (bsc#1184193).
- CVE-2021-28688: Fixed an issue introduced by XSA-365 (bsc#1183646).
- CVE-2021-28660: Fixed an out of bounds write in rtw_wx_set_scan
(bsc#1183593 ).
- CVE-2021-28375: Fixed an issue in fastrpc_internal_invoke which did not
prevent user applications from sending kernel RPC messages (bsc#1183596).
- CVE-2021-28038: Fixed an issue with the netback driver which was lacking
necessary treatment of errors such as failed memory allocations
(bsc#1183022).
- CVE-2021-27365: Fixed an issue where an unprivileged user can send a
Netlink message that is associated with iSCSI, and has a length up to
the maximum length of a Netlink message (bsc#1182715).
- CVE-2021-27364: Fixed an issue where an attacker could craft Netlink
messages (bsc#1182717).
- CVE-2021-27363: Fixed a kernel pointer leak which could have been used
to determine the address of the iscsi_transport structure (bsc#1182716).
- CVE-2020-35519: Fixed an out-of-bounds memory access was found in
x25_bind (bsc#1183696).
- CVE-2020-27815: Fixed an issue in JFS filesystem where could have
allowed an attacker to execute code (bsc#1179454).
- CVE-2020-27171: Fixed an off-by-one error affecting out-of-bounds
speculation on pointer arithmetic, leading to side-channel attacks that
defeat Spectre mitigations and obtain sensitive information from kernel
memory (bsc#1183775).
- CVE-2020-27170: Fixed potential side-channel attacks that defeat Spectre
mitigations and obtain sensitive information from kernel memory
(bsc#1183686).

function (bsc#1159280 ).

triggered when an unexpected port ID number is encountered.
(bnc#1184197).
- CVE-2021-20268: Fixed an out-of-bounds access flaw in the implementation
of the eBPF code verifier. This flaw allowed a local user to crash the
system or possibly escalate their privileges. (bnc#1183077)
- CVE-2020-27673: Fixed a vulnerability with xen, where guest OS users
could cause a denial of service (host OS hang) via a high rate of events
to dom0 (bnc#1177411).
