CVE-2022-0854

The Linux Kernel, the operating system core itself.

Security Fix(es):

st21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has EVT_TRANSACTION buffer overflows because of untrusted length parameters.(CVE-2022-26490)

A memory leak flaw was found in the Linux kernel’s DMA subsystem, in the way a user calls DMA_FROM_DEVICE. This flaw allows a local user to read random memory from the kernel space.(CVE-2022-0854)

** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2022-27666. Reason: This candidate is a reservation duplicate of CVE-2022-27666. Notes: All CVE users should reference CVE-2022-27666 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage.(CVE-2022-0886)

A kernel information leak flaw was identified in the scsi_ioctl function in drivers/scsi/scsi_ioctl.c in the Linux kernel. This flaw allows a local attacker with a special user privilege (CAP_SYS_ADMIN or CAP_SYS_RAWIO) to create issues with confidentiality.(CVE-2022-0494)

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

David Bouman discovered that the netfilter subsystem in the Linux kernel did not properly validate passed user register indices. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-1015)

It was discovered that the block layer subsystem in the Linux kernel did not properly initialize memory in some situations. A privileged local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0494)

It was discovered that the DMA subsystem in the Linux kernel did not properly ensure bounce buffers were completely overwritten by the DMA device. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0854)

Jann Horn discovered that the FUSE file system 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-2022-1011)

David Bouman discovered that the netfilter subsystem in the Linux kernel did not initialize memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-1016)

Hu Jiahui discovered that multiple race conditions existed in the Advanced Linux Sound Architecture (ALSA) framework, leading to use-after-free vulnerabilities. A local attacker could use these to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1048)

It was discovered that the USB Gadget file system interface 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-2022-24958)

It was discovered that the ST21NFCA NFC driver in the Linux kernel did not properly validate the size of certain data in EVT_TRANSACTION events. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-26490)

It was discovered that the USB SR9700 ethernet device driver for the Linux kernel did not properly validate the length of requests from the device. A physically proximate attacker could possibly use this to expose sensitive information (kernel memory). (CVE-2022-26966)

It was discovered that the Xilinx USB2 device gadget driver in the Linux kernel did not properly validate endpoint indices from the host. A physically proximate attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-27223)

赵子轩 discovered that the 802.2 LLC type 2 driver in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could use this to cause a denial of service. (CVE-2022-28356)
