Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a receive RX buffer size alignment and atomic operation exception in the net:mana component...

CVE-2024-40992

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix responder length checking for UD request packets According to the IBA specification: If a UD request packet is detected with an invalid length, the request shall be an invalid request and it shall be silently droppe...

CVE-2024-40992

CVE-2024-40992 concerns the Linux kernel RDMA/rxe stack. The root cause was an incorrect resilience check for UD QP receive data: a deferred responder length check in the function copy_data (via commit 689c5421bfe0) could trigger an oversized UD packet to fail with -EINVAL, causing send_data_in t...

CVE-2021-47474

A flaw was found in the vmk80xx module in the Linux kernel. A malicious device can overflow the slab-allocated receive buffer when doing bulk transfers, resulting in a denial of service...

SUSE CVE-2021-47474

In the Linux kernel, the following vulnerability has been resolved: comedi: vmk80xx: fix bulk-buffer overflow The driver is using endpoint-sized buffers but must not assume that the tx and rx buffers are of equal size or a malicious device could overflow the slab-allocated receive buffer when doi...

kernel: tty: n_gsm: add sanity check for gsm->receive in gsm_receive_buf()

In the Linux kernel, the following vulnerability has been resolved: tty: ngsm: add sanity check for gsm-receive in gsmreceivebuf A null pointer dereference can happen when attempting to access the "gsm-receive" function in gsmldreceivebuf. Currently, the code assumes that gsm-recieve is only call...

CVE-2021-47474

CVE-2021-47474 affects the Linux kernel driver family for comedi vmk80xx. The vulnerability arises from the driver using endpoint-sized buffers while assuming tx and rx buffers are equal size; a malicious device could overflow the slab-allocated receive buffer during bulk transfers. The issue is ...

DEBIAN-CVE-2022-48690

In the Linux kernel, the following vulnerability has been resolved: ice: Fix DMA mappings leak Fix leak, when user changes ring parameters. During reallocation of RX buffers, new DMA mappings are created for those buffers. New buffers with different RX ring count should substitute older ones, but...

kernel: IGB driver inadequate buffer size for frames larger than MTU

A flaw was found in igbconfigurerxring in drivers/net/ethernet/intel/igb/igbmain.c in the IGB driver in the Linux kernel. An overflow of the contents from a packet that is too large will overflow into the kernel's ring buffer, leading to a system integrity issue...

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.8.0-rc7 Description: The vulnerability is related to the btnxpuart component in the Linux kernel, specifically with the btnxpuart close function. It is caused by improper input validation, which can lead to a...

SUSE CVE-2023-6693

A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtionetflushtx function if guest features VIRTIONETFHASHREPORT, VIRTIOFVERSION1 and VIRTIONETFMRGRXBUF are enabled. This could allow a malicious user to overwrite local variables...
