Synopsis

Description

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

The following security bugs were fixed :

- CVE-2020-29371: An issue was discovered in romfs_dev_read in fs/romfs/storage.c where uninitialized memory leaks 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-2020-4788: 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-2018-20669: An issue where a provided address with access_ok() is not checked was discovered in i915_gem_execbuffer2_ioctl in drivers/gpu/drm/i915/i915_gem_execbuffer.c, where a local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a Denial of Service or privilege escalation (bnc#1122971).

- 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: Restrict RTAS requests from userspace (CVE-2020-27777 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).
