Ubuntu Security Notice USN-6231-1
July 14, 2023 linux-oem-6.1 vulnerabilities
========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 22.04 LTS Summary: Several security issues were fixed in the Linux kernel. Software Description:
- linux-oem-6.1: Linux kernel for OEM systems Details: It was discovered that the XFS file system implementation in the Linux
kernel did not properly perform metadata validation when mounting certain
images. An attacker could use this to specially craft a file system image
that, when mounted, could cause a denial of service (system crash).
(CVE-2023-2124) It was discovered that the IP-VLAN network driver for the Linux kernel did
not properly initialize memory in some situations, leading to an out-of-
bounds write vulnerability. An attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2023-3090) It was discovered that the DVB Core driver in the Linux kernel did not
properly handle locking events in certain situations. A local attacker
could use this to cause a denial of service (kernel deadlock).
(CVE-2023-31084) It was discovered that the Ricoh R5C592 MemoryStick card reader driver in
the Linux kernel contained a race condition during module unload, leading
to a use-after-free vulnerability. A local attacker could use this to cause
a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-3141) Yang Lan discovered that the GFS2 file system implementation in the Linux
kernel could attempt to dereference a null pointer in some situations. An
attacker could use this to construct a malicious GFS2 image that, when
mounted and operated on, could cause a denial of service (system crash).
(CVE-2023-3212) Update instructions: The problem can be corrected by updating your system to the following
package versions: Ubuntu 22.04 LTS: linux-image-6.1.0-1016-oem 6.1.0-1016.16 linux-image-oem-22.04c 6.1.0.1016.16 After a standard ..
