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…

A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries platform) a root like local user could use this flaw to further increase their privileges to that of a running kernel.

The Linux Kernel, the operating system core itself.

Security Fix(es):

A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.(CVE-2020-14351)

An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash via events for an in-reconfiguration paravirtualized device, aka CID-073d0552ead5.(CVE-2020-27675)

A flaw was found in the Linux kernel. A use-after-free was found in the way the console subsystem was using ioctls KDGKBSENT and KDSKBSENT. A local user could use this flaw to get read memory access out of bounds. The highest threat from this vulnerability is to data confidentiality.(CVE-2020-25656)

Improper access control in BlueZ may allow an unauthenticated user to potentially enable information disclosure via adjacent access.(CVE-2020-12352)

A locking issue was discovered in the tty subsystem of the Linux kernel through 5.9.13. drivers/tty/tty_jobctrl.c allows a use-after-free attack against TIOCSPGRP, aka CID-54ffccbf053b.(CVE-2020-29661)

Ein Angreifer aus dem angrenzenden Netzwerk oder ein entfernter anonymer, authentisierter oder lokaler Angreifer kann mehrere Schwachstellen in Juniper Junos Space ausnutzen, um Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, einen Denial-of-Service-Zustand auszulösen, beliebigen Code auszuführen und seine Privilegien zu erweitern.
