Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the use of signed integers in bloblen and nummon functions within cephmonmapdecode. This can lead...

PT-2026-38946

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in libceph where the system fails to properly verify the length of key material during decoding. Specifically, the process auth done function does not ensure that the key...

PT-2026-39066

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the libceph component where the ceph monmap decode function uses signed int variables for blob len and num mon. Because these variables are intended to hold non-negati...

PT-2026-39081

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the Ceph component of the Linux kernel where an i nlink counter underrun can occur during an asynchronous unlink operation. In the ceph unlink function, a request is...

Linux Distros Unpatched Vulnerability : CVE-2026-43419

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ceph: fix memory leaks in cephmdscbuildpath Add putname calls to error code paths that did not free the path pointer obtained by getname. If ownership of this...

Linux Distros Unpatched Vulnerability : CVE-2026-43420

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ceph: fix inlink underrun during async unlink During async unlink, we drop the inlink counter before we receive the completion that will eventually update the...

PT-2026-39068

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An out-of-bounds access exists in the ceph handle auth reply function within libceph, triggered by a message of type 'CEPH MSG AUTH REPLY'. The issue occurs because the payload len field...

CVE-2026-43273

A flaw was found in the Linux kernel's Ceph file system module. The cephzeropartialobject function, responsible for handling object write operations, was missing proper snapshot context. This oversight could allow a local attacker to cause data inconsistencies within snapshots, leading to a loss ...

Linux Distros Unpatched Vulnerability : CVE-2026-43188

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ceph: do not propagate page array emplacement errors as batch errors When fscrypt is enabled, movedirtyfolioinpagearray may fail because it needs to allocate...
