ALSA-2021:4356 — Moderate: kernel security, bug fix, and enhancement update

Affected: AlmaLinux:8: kernel-tools-libs-devel

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es): * kernel: out-of-bounds reads in pinctrl subsystem (CVE-2020-0427) * kernel: Improper input validation in some Intel(R) Ethernet E810 Adapter drivers (CVE-2020-24502) * kernel: Insufficient access control in some Intel(R) Ethernet E810 Adapter drivers (CVE-2020-24503) * kernel: Uncontrolled resource consumption in some Intel(R) Ethernet E810 Adapter drivers (CVE-2020-24504) * kernel: Fragmentation cache not cleared on reconnection (CVE-2020-24586) * kernel: Reassembling fragments encrypted under different keys (CVE-2020-24587) * kernel: wifi frame payload being parsed incorrectly as an L2 frame (CVE-2020-24588) * kernel: Forwarding EAPOL from unauthenticated wifi client (CVE-2020-26139) * kernel: accepting plaintext data frames in protected networks (CVE-2020-26140) * kernel: not verifying TKIP MIC of fragmented frames (CVE-2020-26141) * kernel: accepting fragmented plaintext frames in protected networks (CVE-2020-26143) * kernel: accepting unencrypted A-MSDU frames that start with RFC1042 header (CVE-2020-26144) * kernel: accepting plaintext broadcast fragments as full frames (CVE-2020-26145) * kernel: powerpc: RTAS calls can be used to compromise kernel integrity (CVE-2020-27777) * kernel: locking inconsistency in tty_io.c and tty_jobctrl.c can lead to a read-after-free (CVE-2020-29660) * kernel: buffer overflow in mwifiex_cmd_802_11_ad_hoc_start function via a long SSI…

fkie_cve-2021-29650

An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows 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, aka CID-175e476b8cdf.

OESA-2021-1176 — kernel security update

Affected: openEuler:20.03-LTS-SP1: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c 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, aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit.(CVE-2020-27170)

An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error (with a resultant integer underflow) affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-10d2bb2e6b1d.(CVE-2020-27171)

rtw_wx_set_scan in drivers/staging/rtl8188eu/os_dep/ioctl_linux.c in the Linux kernel through 5.11.6 allows writing beyond the end of the ->ssid[] array. NOTE: from the perspective of kernel.org releases, CVE IDs are not normally used for drivers/staging/* (unfinished work); however, system integrators may have situations in which a drivers/staging issue is relevant to their own customer base.(CVE-2021-28660)

A race condition was discovered in get_old_root in fs/btrfs/ctree.c in the Linux kernel through 5.11.8. It allows attackers to cause a denial of service (BUG) because of a lack of locking on an extent buffer before a cloning operation, aka CID-dbcc7d57bffc.(CVE-2021-28964)

WID-SEC-W-2022-0515 — IBM Spectrum Protect: Mehrere Schwachstellen

Ein entfernter, anonymer, authentisierter oder lokaler Angreifer kann mehrere Schwachstellen in IBM Spectrum Protect ausnutzen, um einen Denial-of-Service-Zustand herbeizuführen, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, beliebigen Code auszuführen, seine Rechte zu erweitern oder beliebigen Code mit Root-Rechten auszuführen.
