TITLE

Linux Kernel  Authentication vulnerability in

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. Linux Kernel There is an authentication vulnerability in.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Attackers can use this vulnerability to bypass the restrictions of the Linux kernel through Cgroup Fd Writing to elevate their privileges.

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.

CVE-2021-4197 Eric Biederman reported that incorrect permission checks in the cgroup process migration implementation can allow a local attacker to escalate privileges. CVE-2022-0494 The scsi_ioctl() was susceptible to an information leak only exploitable by users with CAP_SYS_ADMIN or CAP_SYS_RAWIO capabilities. CVE-2022-0812 It was discovered that the RDMA transport for NFS (xprtrdma) miscalculated the size of message headers, which could lead to a leak of sensitive information between NFS servers and clients. CVE-2022-0854 Ali Haider discovered a potential information leak in the DMA subsystem. On systems where the swiotlb feature is needed, this might allow a local user to read sensitive information. CVE-2022-1011 Jann Horn discovered a flaw in the FUSE (Filesystem in User-Space) implementation. A local user permitted to mount FUSE filesystems could exploit this to cause a use-after-free and read sensitive information. CVE-2022-1012, CVE-2022-32296 Moshe Kol, Amit Klein, and Yossi Gilad discovered a weakness in randomisation of TCP source port selection. 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. A local attacker can take advantage of this to read sensitive information. CVE-2022-1048 Hu Jiahui discovered a race condition in the sound subsystem that can result in a use-after-free. CVE-2022-1184 A flaw was discovered in the ext4 filesystem driver which can lead to a use-after-free. A local user permitted to mount arbitrary filesystems could exploit this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation. CVE-2022-1195 Lin Ma discovered race conditions in the 6pack and mkiss hamradio drivers, which could lead to a use-after-free. CVE-2022-1198 Duoming Zhou discovered a race condition in the 6pack hamradio driver, which could lead to a use-after-free. 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. A local user can receive a netlink message when an IPsec daemon registers with the kernel, and this could include sensitive information. CVE-2022-1419 Minh Yuan discovered a race condition in the vgem virtual GPU driver that can lead to a use-after-free. A local user permitted to access the GPU device can exploit this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation. 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. CVE-2022-1652 Minh Yuan discovered a race condition in the floppy driver that can lead to a use-after-free. A local user permitted to access a floppy drive device can exploit this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation. CVE-2022-1729 Norbert Slusarek discovered a race condition in the perf subsystem which could result in local privilege escalation to root. The default settings in Debian prevent exploitation unless more permissive settings have been applied in the kernel.perf_event_paranoid sysctl. CVE-2022-1734 Duoming Zhou discovered race conditions in the nfcmrvl NFC driver that could lead to a use-after-free, double-free or null pointer dereference. This driver is not enabled in Debian's official kernel configurations. CVE-2022-1974, CVE-2022-1975 Duoming Zhou discovered that the NFC netlink interface was suspectible to denial of service. CVE-2022-2153 "kangel" reported a flaw in the KVM implementation for x86 processors which could lead to a null pointer dereference. CVE-2022-21123, CVE-2022-21125, CVE-2022-21166 Various researchers discovered flaws in Intel x86 processors, collectively referred to as MMIO Stale Data vulnerabilities. These are similar to the previously published Microarchitectural Data Sampling (MDS) issues and could be exploited by local users to leak sensitive information. For some CPUs, the mitigations for these issues require updated microcode. An updated intel-microcode package may be provided at a later date. The updated CPU microcode may also be available as part of a system firmware ("BIOS") update. Further information on the mitigation can be found at <https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/processor_mmio_stale_data.html> or in the linux-doc-4.19 package. CVE-2022-23960 Researchers at VUSec discovered that the Branch History Buffer in Arm processors can be exploited to create information side- channels with speculative execution. This issue is similar to Spectre variant 2, but requires additional mitigations on some processors. This was previously mitigated for 32-bit Arm (armel and armhf) architectures and is now also mitigated for 64-bit Arm (arm64). This can be exploited to obtain sensitive information from a different security context, such as from user-space to the kernel, or from a KVM guest to the kernel. CVE-2022-26490 Buffer overflows in the STMicroelectronics ST21NFCA core driver can result in denial of service or privilege escalation. This driver is not enabled in Debian's official kernel configurations. CVE-2022-27666 "valis" reported a possible buffer overflow in the IPsec ESP transformation code. CVE-2022-28356 "Beraphin" discovered that the ANSI/IEEE 802.2 LLC type 2 driver did not properly perform reference counting on some error paths. CVE-2022-28388 A double free vulnerability was discovered in the 8 devices USB2CAN interface driver. CVE-2022-28389 A double free vulnerability was discovered in the Microchip CAN BUS Analyzer interface driver. CVE-2022-28390 A double free vulnerability was discovered in the EMS CPC-USB/ARM7 CAN/USB interface driver. CVE-2022-29581 Kyle Zeng discovered a reference-counting bug in the cls_u32 network classifier which can lead to a use-after-free. CVE-2022-30594 Jann Horn discovered a flaw in the interaction between ptrace and seccomp subsystems. A process sandboxed using seccomp() but still permitted to use ptrace() could exploit this to remove the seccomp restrictions. CVE-2022-32250 Aaron Adams discovered a use-after-free in Netfilter which may result in local privilege escalation to root. CVE-2022-33981 Yuan Ming from Tsinghua University reported a race condition in the floppy driver involving use of the FDRAWCMD ioctl, which could lead to a use-after-free. A local user with access to a floppy drive device could exploit this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation. This ioctl is now disabled by default. For the oldstable distribution (buster), these problems have been fixed in version 4.19.249-2. Due to an issue in the signing service (Cf. Debian bug #1012741), the vport-vxlan module cannot be loaded for the signed kernel for amd64 in this update. This update also corrects a regression in the network scheduler subsystem (bug #1013299). For the 32-bit Arm (armel and armhf) architectures, this update enables optimised implementations of several cryptographic and CRC algorithms. For at least AES, this should remove a timing side- channel that could lead to a leak of sensitive information. This update includes many more bug fixes from stable updates 4.19.236-4.19.249 inclusive, including for bug #1006346. The random driver has been backported from Linux 5.19, fixing numerous performance and correctness issues. Some changes will be visible: - - The entropy pool size is now 256 bits instead of 4096. You may need to adjust the configuration of system monitoring or user-space entropy gathering services to allow for this. - - On systems without a hardware RNG, the kernel may log more uses of /dev/urandom before it is fully initialised. These uses were previously under-counted and this is not a regression. We recommend that you upgrade your linux packages.
