Synopsis: Important: kernel security and bug fix update Advisory ID: SLSA-2021:3327-1 Issue Date: 2021-08-31 CVE Numbers: CVE-2021-32399 CVE-2021-22555 CVE-2020-27777 CVE-2021-29650 CVE-2021-29154 -- Security Fix(es): * kernel: out-of-bounds write in xt_compat_target_from_user() in net/netfilter/x_tables.c (CVE-2021-22555) * kernel: race condition for removal of the HCI controller (CVE-2021-32399) * kernel: powerpc: RTAS calls can be used to compromise kernel integrity (CVE-2020-27777) * kernel: Local privilege escalation due to incorrect BPF JIT branch displacement computation (CVE-2021-29154) * kernel: lack a full memory barrier upon the assignment of a new table value in net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h may lead to DoS (CVE-2021-29650) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE Bug Fix(es): * SAN Switch rebooted and caused (?) OpenStack compute node to reboot * sysfs: cannot create duplicate filename '/class/mdio_bus/ixgbe-8100 * XFS: read-only recovery does not update free space accounting in superblock * The memcg_params field of kmem_cache struct contains an old slab address that is to small for the current size of memcg_limited_groups_array_size. * Backport of upstream patch "net: Update window_clamp if SOCK_RCVBUF is set " into rhel-7 * Kernel panic in init_cq_frag_buf * futex: futex_requeue can potentially free the pi_state structure twice * be_poll lockup doing ifenslave when netconsole using bond * OCP4.7 nodes panic at BUG_ON in nf_nat_setup_info() --- SL7 x86_64 bpftool-3.10.0-1160.41.1.el7.x86_64.rpm bpftool-debuginfo-3.10.0-1160.41.1.el7.x86_64.rpm kernel-3.10.0-1160.41.1.el7.x86_64.rpm kernel-debug-3.10.0-1160.41.1.el7.x86_64.rpm kernel-debug-debuginfo-3.10.0-1160.41.1.el7.x86_64.rpm kernel-debug-devel-3.10.0-1160.41.1.el7.x86_64.rpm kernel-debuginfo-3.10.0-1160.41.1.el7.x86_64.rpm kernel-debuginfo-common-x86_64-3.10.0-1160.41.1.el7.x86_64.rpm kernel-devel-3.10.0-1160.41.1.el7.x86_64.rpm kernel-headers-3.10.0-1160.41.1.el7.x86_64.rpm kernel-tools-3.10.0-1160.41.1.el7.x86_64.rpm kernel-tools-debuginfo-3.10.0-1160.41.1.el7.x86_64.rpm kernel-tools-libs-3.10.0-1160.41.1.el7.x86_64.rpm kernel-tools-libs-devel-3.10.0-1160.41.1.el7.x86_64.rpm perf-3.10.0-1160.41.1.el7.x86_64.rpm perf-debuginfo-3.10.0-1160.41.1.el7.x86_64.rpm python-perf-3.10.0-1160.41.1.el7.x86_64.rpm python-perf-debuginfo-3.10.0-1160.41.1.el7.x86_64.rpm noarch kernel-abi-whitelists-3.10.0-1160.41.1.el7.noarch.rpm kernel-doc-3.10.0-1160.41.1.el7.noarch.rpm -- - Scientific Linux Development Team
