CVE-2021-4197

TITLE

Debian Security Advisory 5127-1

DESCRIPTION

An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. Attackers can use this vulnerability to bypass the restrictions of the Linux kernel through Cgroup Fd Writing to elevate their privileges. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-5127-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso May 02, 2022 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : linux CVE ID : CVE-2021-4197 CVE-2022-0168 CVE-2022-1016 CVE-2022-1048 CVE-2022-1158 CVE-2022-1195 CVE-2022-1198 CVE-2022-1199 CVE-2022-1204 CVE-2022-1205 CVE-2022-1353 CVE-2022-1516 CVE-2022-26490 CVE-2022-27666 CVE-2022-28356 CVE-2022-28388 CVE-2022-28389 CVE-2022-28390 CVE-2022-29582 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. The security impact is negligible as CAP_SYS_ADMIN inherently gives the ability to deny service. CVE-2022-1016 David Bouman discovered a flaw in the netfilter subsystem where the nft_do_chain function did not initialize register data that nf_tables expressions can read from and write to. CVE-2022-1158 Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered a bug in the KVM implementation for x86 processors. A local user with access to /dev/kvm could cause the MMU emulator to update page table entry flags at the wrong address. CVE-2022-1199, CVE-2022-1204, CVE-2022-1205 Duoming Zhou discovered race conditions in the AX.25 hamradio protocol, which could lead to a use-after-free or null pointer dereference. CVE-2022-1353 The TCS Robot tool found an information leak in the PF_KEY subsystem. CVE-2022-1516 A NULL pointer dereference flaw in the implementation of the X.25 set of standardized network protocols, which can result in denial of service. This driver is not enabled in Debian's official kernel configurations. This driver is not enabled in Debian's official kernel configurations. For the stable distribution (bullseye), these problems have been fixed in version 5.10.113-1. We recommend that you upgrade your linux packages.

Software Description: - linux-azure-5.13: Linux kernel for Microsoft Azure cloud systems - linux-oracle-5.13: Linux kernel for Oracle Cloud systems Details: It was discovered that the BPF verifier in the Linux kernel did not properly restrict pointer types in certain situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-23222) It was discovered that the network traffic control implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1055) Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly restrict access to the cgroups v1 release_agent feature. (CVE-2022-0492) J\xfcrgen Gro\xdf discovered that the Xen subsystem within the Linux kernel did not adequately limit the number of events driver domains (unprivileged PV backends) could send to other guest VMs. An attacker in a driver domain could use this to cause a denial of service in other guest VMs. (CVE-2021-28711, CVE-2021-28712, CVE-2021-28713) J\xfcrgen Gro\xdf discovered that the Xen network backend driver in the Linux kernel did not adequately limit the amount of queued packets when a guest did not process them. An attacker in a guest VM can use this to cause a denial of service (excessive kernel memory consumption) in the network backend domain. (CVE-2021-28714, CVE-2021-28715) Szymon Heidrich discovered that the USB Gadget subsystem in the Linux kernel did not properly restrict the size of control requests for certain gadget types, leading to possible out of bounds reads or writes. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-39685) It was discovered that a race condition existed in the poll implementation in the Linux kernel, resulting in a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-39698) It was discovered that the simulated networking device driver for the Linux kernel did not properly initialize memory in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2021-4135) Eric Biederman discovered that the cgroup process migration implementation in the Linux kernel did not perform permission checks correctly in some situations. (CVE-2021-4197) Brendan Dolan-Gavitt discovered that the aQuantia AQtion Ethernet device driver in the Linux kernel did not properly validate meta-data coming from the device. A local attacker who can control an emulated device can use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-43975) It was discovered that the ARM Trusted Execution Environment (TEE) subsystem in the Linux kernel contained a race condition leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2021-44733) It was discovered that the Phone Network protocol (PhoNet) implementation in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2021-45095) It was discovered that the eBPF verifier in the Linux kernel did not properly perform bounds checking on mov32 operations. A local attacker could use this to expose sensitive information (kernel pointer addresses). (CVE-2021-45402) It was discovered that the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel did not properly deallocate memory in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2021-45480) It was discovered that the BPF subsystem in the Linux kernel did not properly track pointer types on atomic fetch operations in some situations. A local attacker could use this to expose sensitive information (kernel pointer addresses). (CVE-2022-0264) It was discovered that the TIPC Protocol implementation in the Linux kernel did not properly initialize memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0382) Samuel Page discovered that the Transparent Inter-Process Communication (TIPC) protocol implementation in the Linux kernel contained a stack-based buffer overflow. A remote attacker could use this to cause a denial of service (system crash) for systems that have a TIPC bearer configured. (CVE-2022-0435) It was discovered that the KVM implementation for s390 systems in the Linux kernel did not properly prevent memory operations on PVM guests that were in non-protected mode. A local attacker could use this to obtain unauthorized memory write access. (CVE-2022-0516) It was discovered that the ICMPv6 implementation in the Linux kernel did not properly deallocate memory in certain situations. A remote attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2022-0742) It was discovered that the IPsec implementation in the Linux kernel did not properly allocate enough memory when performing ESP transformations, leading to a heap-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-27666) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 20.04 LTS: linux-image-5.13.0-1021-azure 5.13.0-1021.24~20.04.1 linux-image-5.13.0-1025-oracle 5.13.0-1025.30~20.04.1 linux-image-azure 5.13.0.1021.24~20.04.10 linux-image-oracle 5.13.0.1025.30~20.04.1 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
