Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1651-1 advisory.

The SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2018-7755: Fixed an issue in the fd_locked_ioctl function in drivers/block/floppy.c. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discover the location of kernel code and data and bypass kernel security protections such as KASLR (bnc#1084513).
- CVE-2019-20811: Fixed issue in rx_queue_add_kobject() and netdev_queue_add_kobject() in net/core/net- sysfs.c, where a reference count is mishandled (bnc#1172456).
- CVE-2021-20292: Fixed object validation prior to performing operations on the object in nouveau_sgdma_create_ttm in Nouveau DRM subsystem (bnc#1183723).
- CVE-2021-20321: Fixed a race condition accessing file object in the OverlayFS subsystem in the way users do rename in specific way with OverlayFS. A local user could have used this flaw to crash the system (bnc#1191647).
- CVE-2021-38208: Fixed a denial of service (NULL pointer dereference and BUG) by making a getsockname call after a certain type of failure of a bind call (bnc#1187055).
- CVE-2021-43389: Fixed an array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/isdn/capi/kcapi.c (bnc#1191958).
- CVE-2022-1011: Fixed a use-after-free flaw inside the FUSE filesystem in the way a user triggers write(). This flaw allowed a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation (bnc#1197343).
- CVE-2022-1280: Fixed a use-after-free vulnerability in drm_lease_held in drivers/gpu/drm/drm_lease.c (bnc#1197914).
- CVE-2022-1353: Fixed access controll to kernel memory in the pfkey_register function in net/key/af_key.c (bnc#1198516).
- CVE-2022-1419: Fixed a concurrency use-after-free in vgem_gem_dumb_create (bsc#1198742).
- CVE-2022-1516: Fixed null-ptr-deref caused by x25_disconnect (bsc#1199012).
- CVE-2022-23960: Fixed speculation issues in the Branch History Buffer that allowed an attacker to obtain sensitive information using cache allocation (bnc#1196657).
- CVE-2022-28748: Fixed memory lead over the network by ax88179_178a devices (bsc#1196018).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
