The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed:

• CVE-2021-29650: Fixed an issue with the netfilter subsystem that allowed
  attackers to cause a denial of service (panic) because
  net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h lack a
  full memory barrier upon the assignment of a new table value
  (bnc#1184208).
• CVE-2021-29155: Fixed an issue that was discovered in
  kernel/bpf/verifier.c that performs undesirable out-of-bounds
  speculation on pointer arithmetic, leading to side-channel attacks that
  defeat Spectre mitigations and obtain sensitive information from kernel
  memory. Specifically, for sequences of pointer arithmetic operations,
  the pointer modification performed by the first operation was not
  correctly accounted for when restricting subsequent operations
  (bnc#1184942).

The following non-security bugs were fixed:
