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-2021-3659

A NULL pointer dereference flaw was found in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability.

OESA-2021-1310 — kernel security update

Affected: openEuler:20.03-LTS-SP1: kernel, openEuler:20.03-LTS-SP2: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): A NULL pointer dereference flaw was found in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability.(CVE-2021-3659) arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e.(CVE-2021-37576) A vulnerability was found in the Linux kernel in versions before v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory.(CVE-2021-3655).

No description is available for this CVE.(CVE-2022-0850).
