Description:

   This update for the Linux Kernel 4.12.14-150_69 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-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).
