Security update for the Linux Kernel (Live Patch 40 for SLE 12 SP3) SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2022:0328-1 Final 1 1 2022-02-04T08:28:03Z current 2022-02-04T08:28:03Z 2022-02-04T08:28:03Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for the Linux Kernel (Live Patch 40 for SLE 12 SP3) This update for the Linux Kernel 4.4.180-94_147 fixes several issues. The following security issues were fixed: - CVE-2018-25020: Fixed an issue in the BPF subsystem in the Linux kernel mishandled situations with a long jump over an instruction sequence where inner instructions require substantial expansions into multiple BPF instructions, leading to an overflow. (bsc#1193575) - CVE-2020-3702: Fixed a bug which could be triggered with specifically timed and handcrafted traffic and cause internal errors in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure. (bsc#1191193) - CVE-2019-0136: Fixed an insufficient access control which allow an unauthenticated user to execute a denial of service. (bsc#1193157) - CVE-2021-42739: The firewire subsystem had a buffer overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking (bsc#1184673).
