CVE-2021-43056

An issue was discovered in the Linux kernel for powerpc before 5.14.15. It allows a malicious KVM guest to crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S implementation bug in the handling of the SRR1 register values.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

The openSUSE Leap 15.2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

• CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID (bnc#1100416 bnc#1129735).
• CVE-2021-33033: The Linux kernel had a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads to writing an arbitrary value (bnc#1186109 bnc#1188876).
• CVE-2021-34556: An unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects the possibility of uninitialized memory locations on the BPF stack (bnc#1188983).
• CVE-2021-35477: An unprivileged BPF program can obtain sensitive information from kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store operation did not necessarily occur before a store operation that has an attacker-controlled value (bnc#1188985).
• CVE-2021-3655: Missing size validations on inbound SCTP packets may have allowed the kernel to read uninitialized memory (bnc#1188563 bnc#1192267).
• CVE-2021-3715: Fixed a use-after-free in route4_change() in net/sched/cls_route.c (bsc#1190349).
• CVE-2021-3760: Fixed a use-after-free vulnerability with the ndev->rf_conn_info object (bsc#1190067).
• CVE-2021-3772: Invalid chunks may be used to remotely remove existing associations (bsc#1190351).
• CVE-2021-3896: Fixed a array-index-out-bounds in detach_capi_ctr in drivers/isdn/capi/kcapi.c (bsc#1191958).
• CVE-2021-41864: prealloc_elems_and_freelist in kernel/bpf/stackmap.c allowed unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write (bnc#1191317).
• CVE-2021-42008: The decode_data function in drivers/net/hamradio/6pack.c had a slab out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access (bnc#1191315).
• CVE-2021-42252: An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c where local attackers were able to access the Aspeed LPC control interface could overwrite memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a certain comparison uses values that are not memory sizes (bnc#1190479).
• 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 (bnc#1184673 bnc#1192036).
• 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).
• CVE-2021-43056: It allowed a malicious KVM guest to crash the host, when the host is running on Power8, due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S implementation bug in the handling of the SRR1 register values (bnc#1192107).

Ilja Van Sprundel discovered that the SCTP implementation in the Linux kernel did not properly perform size validations on incoming packets in some situations. An attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2021-3655)

It was discovered that the AMD Cryptographic Coprocessor (CCP) driver in the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2021-3744, CVE-2021-3764)

It was discovered that the NFC subsystem in the Linux kernel contained a use-after-free vulnerability in its NFC Controller Interface (NCI) implementation. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-3760)

It was discovered that an integer overflow could be triggered in the eBPF implementation in the Linux kernel when preallocating objects for stack maps. A privileged local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2021-41864)
