Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Incorrect calculation
EUVDB-ID: #VU99182
Risk: Low
CVSSv4.0: 4.3 [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:U/U:Clear]
CVE-ID: CVE-2022-49014
CWE-ID:
CWE-682 - Incorrect Calculation
Exploit availability: No
DescriptionThe vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect calculation within the __tun_detach() and tun_detach() functions in drivers/net/tun.c. A local user can perform a denial of service (DoS) attack.
MitigationUpdate the affected package the Linux Kernel (Live Patch 49 for SLE 15 SP3) to the latest version.

2) Integer underflow
EUVDB-ID: #VU104788
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-2022-49563
CWE-ID:
CWE-191 - Integer underflow
Exploit availability: No
DescriptionThe vulnerability allows a local user to execute arbitrary code.
The vulnerability exists due to integer underflow within the qat_rsa_enc() and qat_rsa_dec() functions in drivers/crypto/qat/qat_common/qat_asym_algs.c. A local user can execute arbitrary code.
MitigationUpdate the affected package the Linux Kernel (Live Patch 49 for SLE 15 SP3) to the latest version.
