openSUSE Security Update : the Linux Kernel (openSUSE-2020-2161)

medium Nessus Plugin ID 143523
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote openSUSE host is missing a security update.

Description

The openSUSE Leap 15.2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

- CVE-2020-29369: There was a race condition between certain expand functions (expand_downwards and expand_upwards) and page-table free operations from an munmap call, aka CID-246c320a8cfe (bnc#1173504 bnc#1179432).

- CVE-2020-29371: An issue was discovered in romfs_dev_read in fs/romfs/storage.c, where uninitialized memory could leak to userspace, aka CID-bcf85fcedfdd (bnc#1179429).

- CVE-2020-15436: Use-after-free vulnerability in fs/block_dev.c allowed local users to gain privileges or cause a denial of service by leveraging improper access to a certain error field (bnc#1179141).

- CVE-2020-25705: A flaw in the way reply ICMP packets are limited was found that allowed to quickly scan open UDP ports. This flaw allowed an off-path remote user to effectively bypassing source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source port randomization are indirectly affected as well. Kernel versions may be vulnerable to this issue (bnc#1175721 bnc#1178782).

- CVE-2020-15437: The Linux kernel was vulnerable to a NULL pointer dereference in drivers/tty/serial/8250/8250_core.c:serial8250_isa_init_ ports() that allowed local users to cause a denial of service by using the p->serial_in pointer which uninitialized (bnc#1179140).

- CVE-2020-27777: Restricted RTAS requests from userspace (bsc#1179107).

- CVE-2020-28974: A slab-out-of-bounds read in fbcon could be used by local attackers to read privileged information or potentially crash the kernel, aka CID-3c4e0dff2095. This occurs because KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for manipulations such as font height (bnc#1178589).

- CVE-2020-4788: IBM Power9 (AIX 7.1, 7.2, and VIOS 3.1) processors could allow a local user to obtain sensitive information from the data in the L1 cache under extenuating circumstances. IBM X-Force ID: 189296 (bnc#1177666).

- CVE-2020-28941: Local attackers on systems with the speakup driver could cause a local denial of service attack, aka CID-d41227544427. This occurs because of an invalid free when the line discipline is used more than once (bnc#1178740).

- CVE-2020-28915: A buffer over-read (at the framebuffer layer) in the fbcon code could be used by local attackers to read kernel memory, aka CID-6735b4632def (bnc#1178886).

- CVE-2020-25669: Avoid a use-after-free in teardown paths in sunkbd (bsc#1178182).
