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, which stems from the presence of a kernel pointer leak...

CVE-2021-46938

In the Linux kernel, the following vulnerability has been resolved: dm rq: fix double free of blkmqtagset in dev remove after table load fails When loading a device-mapper table for a request-based mapped device, and the allocation/initialization of the blkmqtagset for the device fails, a followi...

kernel: speculative pointer dereference in do_prlimit() in kernel/sys.c

A vulnerabilty was found in Linux Kernel, where a speculative pointer dereference problem exists in the Linux Kernel on the doprlimit function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents...

kernel: uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM

A flaw was found in the Linux kernel in net/netfilter/nftablescore.c:nftdochain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker...

CVE-2023-0459 Copy_from_user Spectre-V1 Gadget in Linux Kernel

Copyfromuser on 64-bit versions of the Linux kernel does not implement the uaccessbeginnospec allowing a user to bypass the "accessok" check and pass a kernel pointer to copyfromuser. This would allow an attacker to leak information. We recommend upgrading beyond...

SUSE CVE-2013-2195

The Elf parser libelf in Xen 4.2.x and earlier allow local guest administrators with certain permissions to have an unspecified impact via a crafted kernel, related to "pointer dereferences" involving unexpected calculations...

SUSE CVE-2019-9455

In the Android kernel in the video driver there is a kernel pointer leak due to a WARNON statement. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation...

CVE-2022-42464 Kernel memory pool override in /dev/mmz_userdev device driver. The impact depends on the privileges of the attacker. The unprivileged process run on the device could disclose sensitive information including kernel pointer, which could be used in furth ...

OpenHarmony-v3.1.2 and prior versions, 3.0.6 and prior versions have a Kernel memory pool override vulnerability in /dev/mmzuserdev device driver. The impact depends on the privileges of the attacker. The unprivileged process run on the device could disclose sensitive information including kernel...

Nutanix AOS : Multiple Vulnerabilities (NXSA-AOS-5.15.6)

The version of AOS installed on the remote host is prior to 5.15.6. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.15.6 advisory. - encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service invalid write access and...

CVE-2022-20064

In ccci, there is a possible leak of kernel pointer due to an incorrect bounds check. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS06108617; Issue ID: ALPS06108617...
