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 Linux kernel that originates from page fragment corruption due to a page fault in the tcp module...

CVE-2021-47480

In the Linux kernel, the following vulnerability has been resolved: scsi: core: Put LLD module refcnt after SCSI device is released SCSI host release is triggered when SCSI device is freed. We have to make sure that the low-level device driver module won't be unloaded before SCSI host instance is...

CVE-2023-52866

xorg-x11-server: Heap buffer overread/data leakage in ProcXIGetSelectedEvents

A heap-based buffer over-read vulnerability was found in the X.org server's ProcXIGetSelectedEvents function. This issue occurs when byte-swapped length values are used in replies, potentially leading to memory leakage and segmentation faults, particularly when triggered by a client with a...

CVE-2021-47350

In the Linux kernel, the following vulnerability has been resolved: powerpc/mm: Fix lockup on kernel exec fault The powerpc kernel is not prepared to handle exec faults from kernel. Especially, the function isexecfault will return 'false' when an exec fault is taken by kernel, because the check i...

python-cryptography: NULL-dereference when loading PKCS7 certificates

A null-pointer dereference vulnerability was found in python-cryptography during the loading of PKCS7 certificates. Invoking "loadpempkcs7certificates" or "loadderpkcs7certificates" can trigger this issue and lead to subsequent segmentation fault and result in a Denial of Service DoS for any...

CVE-2021-47480

CVE-2021-47480 affects the Linux kernel SCSI subsystem. The issue arises when releasing a SCSI host: the low-level device driver (LLD) module could be unloaded before the SCSI host is fully released, because shost->hostt is needed during release, leading to a kernel panic (BUG: unable to handl...
