SUSE: Security Advisory (SUSE-SU-2021:2427-1)

The remote host is missing an update for the 'Linux Kernel' package(s) announced via the SUSE-SU-2021:2427-1 advisory.

The SUSE Linux Enterprise 15 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-2021-33624: Fixed a bug which allows unprivileged BPF program to leak the contents of arbitrary kernel memory (and therefore, of all physical memory) via a side-channel. (bsc#1187554) 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-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. (bnc#1179610) 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-2021-0129: Fixed an improper access control in BlueZ that may have allowed an authenticated user to potentially enable information disclosure via adjacent access. (bnc#1186463) 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 bsc#1185863) CVE-2021-33909: Fixed an out-of-bounds write in the filesystem layer that allows to andobtain 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-2020-36385: Fixed a use-after-free flaw in ucma.c which allows for local privilege escalation. (bsc#1187050) CVE-2021-33200: Fix leakage of uninitialized bpf stack under speculation. (bsc#1186484) The following non-security bugs were fixed: af_packet: fix the tx skb protocol in raw sockets with ETH_P_ALL (bsc#1176081). kabi: preserve struct header_ops after bsc#1176081 fix (bsc#1176081). net: Do not set transport offset to invalid value (bsc#1176081). net: Introduce parse_protocol header_ops callback (bsc#1176081). net/ethernet: Add parse_protocol header_ops support (bsc#1176081). net/mlx5e: Remove the wrong assumption about transport offset (bsc#1176081). net/mlx5e: Trust kernel regarding transport offset (bsc#1176081). net/packet: Ask driver for protocol if not provided by user (bsc#1176081). net/packet: Remove redundant skb->protocol set (bsc#1176081). resource: Fix find_next_iomem_res() iteration issue (bsc#1181193). scsi: scsi_dh_alua: Retry RTPG on a ...
