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: locking issue in drivers/tty/tty_jobctrl.c can lead to an use-after-free (CVE-2020-29661)

* kernel: performance counters race condition use-after-free (CVE-2020-14351)

* kernel: ICMP rate limiting can be used for DNS poisoning attack (CVE-2020-25705)

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.

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.

An attacker could cause a crash or potentially execute arbitrary code by sending specially crafted DNS responses to the DNSmasq process. In order to exploit this vulnerability, an attacker must be able to trigger DNS requests from the device, and must be in a privileged position to inject malicious DNS responses. An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187. In checkKeyIntent of AccountManagerService.java, there is a possible permission bypass. This could lead to local information disclosure with User execution privileges needed. User interaction is needed for exploitation. Product: Android Versions: Android-10, Android-9 Android ID: A-123700107 In setNiNotification of GpsNetInitiatedHandler.java, there is a possible permissions bypass due to an empty mutable PendingIntent. This could lead to local escalation of privilege with User execution privileges needed. User interaction is not needed for exploit…

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