The following security issues were fixed: - Fix a kernel warning during sysfs read (bsc#1186235) - CVE-2020-36322: An issue was discovered in the FUSE filesystem implementation in the Linux kernel aka CID-5d069dbe8aaf. fuse_do_getattr() calls make_bad_inode() in inappropriate situations, causing a system crash. NOTE: the original fix for this vulnerability was incomplete, and its incompleteness is tracked as CVE-2021-28950 (bsc#1184952). - CVE-2021-29154: BPF JIT compilers in the Linux kernel have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context. This affects arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c (bsc#1184710) The CVRF data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).
