SUSE update for the Linux Kernel

1) Use-after-free

EUVDB-ID: #VU28418

Risk: Low

CVSSv3.1: 6.4 [CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-19377

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

The vulnerability allows a local non-authenticated attacker to execute arbitrary code.

In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c.

Update the affected package the Linux Kernel to the latest version.

The vulnerability exists due to granularity of the grant table doesn't allow sharing less than a 4K page, leading to unrelated data residing in the same 4K page as data shared with a backend being accessible by such backend. A local user can gain unauthorized access to sensitive information on the system.

Update the affected package the Linux Kernel to the latest version.
