The SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - 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-2021-28038: 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-2021-26932: Fixed improper error handling issues in Linux grant mapping (XSA-361 bsc#1181747). - CVE-2021-26931: Fixed an issue where Linux kernel was treating grant mapping errors as bugs (XSA-362 bsc#1181753). - CVE-2021-26930: Fixed an improper error handling in blkback's grant mapping (XSA-365 bsc#1181843). - CVE-2020-35519: Fixed an out-of-bounds memory access was found in x25_bind (bsc#1183696). - CVE-2020-29368,CVE-2020-29374: Fixed an issue in copy-on-write implementation which could have granted unintended write access (bsc#1179660, bsc#1179428). - 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). - CVE-2020-0433: Fixed a use after free due to improper locking which could have led to local escalation of privilege (bsc#1176720). - CVE-2021-3483: Fixed a use-after-free in nosy.c (bsc#1184393). - CVE-2021-30002: Fixed a memory leak for large arguments in video_usercopy (bsc#1184120). - CVE-2021-29154: Fixed incorrect computation of branch displacements, allowing arbitrary code execution (bsc#1184391). - CVE-2021-20219: Fixed a denial of service in n_tty_receive_char_special (bsc#1184397). - CVE-2020-36311: Fixed a denial of service (soft lockup) by triggering destruction of a large SEV VM (bsc#1184511). - CVE-2020-25670, CVE-2020-25671, CVE-2020-25672, CVE-2020-25673: Fixed multiple bugs in NFC subsytem (bsc#1178181).
