QID 750880: SUSE Enterprise Linux Security Update for the Linux Kernel (SUSE-SU-2021:2451-1)
The suse linux enterprise 12 sp3 kernel was updated to receive various security and bugfixes.
the following security bugs were fixed: - cve-2021-22555: fixed an heap out-of-bounds write in net/netfilter/x_tables.c that could allow local provilege escalation.
(bsc#1188116) - cve-2021-33909: fixed an out-of-bounds write in the filesystem layer that allows to obtain full root privileges. (
Bsc#1188062) - cve-2021-3609: fixed a race condition in the can bcm networking protocol which allows for local privilege escalation. (
Bsc#1187215) - cve-2021-0605: fixed an out-of-bounds read which could lead to local information disclosure in the kernel with system execution privileges needed. (
Bsc#1187601) - cve-2021-0512: fixed a possible out-of-bounds write which could lead to local escalation of privilege with no additional execution privileges needed. (
Bsc#1187595) - cve-2021-34693: fixed a bug in net/can/bcm.c which could allow local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized. (
Bsc#1187452) - cve-2020-36385: fixed a use-after-free flaw in ucma.c which allows for local privilege escalation. (
Bsc#1187050) - cve-2021-0129: fixed an improper access control in bluez that may have allowed an authenticated user to potentially enable information disclosure via adjacent access. (
Bsc#1186463) - cve-2020-26558: fixed a flaw in the bluetooth le and br/edr secure pairing that could permit a nearby man-in-the-middle attacker to identify the passkey used during pairing. (
Bsc#1179610) - cve-2020-36386: fixed an out-of-bounds read in hci_extended_inquiry_result_evt. (
Bsc#1187038) - cve-2020-24588: fixed a bug that could allow an adversary to abuse devices that support receiving non-ssp a-msdu frames to inject arbitrary network packets. (
Bsc#1185861) - cve-2021-32399: fixed a race condition in net/bluetooth/hci_request.c for removal of the hci controller. (
Bsc#1184611) - cve-2021-33034: fixed an issue in net/bluetooth/hci_event.c where a use-after-free leads to writing an arbitrary value. (
Bsc#1186111) - cve-2020-26139: fixed a bug that allows an access point (ap) to forward eapol frames to other clients even though the sender has not yet successfully authenticated.
This might be abused in projected wi-fi networks to launch denial-of-service attacks against connected clients and made it easier to exploit other vulnerabilities in connected clients. (
Bsc#1186062) - cve-2021-23134: fixed a use after free vulnerability in nfc sockets which allows local attackers to elevate their privileges. (
Bsc#1186060) - cve-2020-24586: fixed a bug that, under the right circumstances, allows to inject arbitrary network packets and/or exfiltrate user data when another device sends fragmented frames encrypted using wep, ccmp, or gcmp. (
Bsc#1185859) - cve-2020-26141: fixed a flaw that could allows an adversary to inject and possibly decrypt packets in wpa or wpa2 networks that support the tkip data-confidentiality protocol. (
Bsc#1185987) - cve-2020-26145: fixed a bug in the wep, wpa, wpa2, and wpa3 implementations that could allows an adversary to inject arbitrary network packets. (
Bsc#1185860) - cve-2020-24587: fixed a bug that allows an adversary to decrypt selected fragments when another device sends fragmented frames and the wep, ccmp, or gcmp encryption key is periodically renewed. (
Bsc#1185862) - cve-2020-26147: fixed a bug in the wep, wpa, wpa2, and wpa3 implementations that could allows an adversary to inject packets and/or exfiltrate selected fragments when another device sends fragmented frames. (
Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.
Successful exploitation allows attacker to compromise the system.
