25) Privilege escalation
EUVDB-ID: #VU11228
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2018-8822
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists in the ncp_read_kernel function due to incorrect buffer length handling. A local attacker can submit specially crafted data from a malicious NCPFS server, trigger memory corruption and execute arbitrary code with root privileges.

26) NULL pointer dereference
EUVDB-ID: #VU12185
Risk: Low
CVSSv4.0: 5.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2018-10323
CWE-ID:
CWE-476 - NULL Pointer Dereference
Exploit availability: No
DescriptionThe vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists in the xfs_bmap_extents_to_btree function in the fs/xfs/libxfs/xfs_bmap.c source code file due to NULL pointer dereference when handling Extended File System (XFS) images. A local attacker can mount a specially crafted XFS filesystem image when filesystem operations are executed on the mounted image and cause the service to crash.
