Description:

This update for the Linux Kernel 4.4.180-94_141 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-2020-25670, CVE-2020-25671, CVE-2020-25672, CVE-2020-25673, CVE-2021-23134: Fixed multiple bugs in NFC subsytem (bsc#1178181, bsc#1186060).
• 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).
