CVE-2026-43405

In the Linux kernel, the following vulnerability has been resolved: libceph: Use u32 for non-negative values in cephmonmapdecode This patch fixes unnecessary implicit conversions that change signedness of bloblen and nummon in cephmonmapdecode. Currently bloblen and nummon are signed int variable...

CVE-2026-43405

CVE-2026-43405 affects the Linux kernel libceph component, specifically ceph_monmap_decode(). The root cause is signedness mishandling: blob_len and num_mon are int, used to hold non-negative values that should be unsigned, leading to potential large allocations when an incoming num_mon is very l...

CVE-2026-43304

CVE-2026-43304 affects the Linux kernel libceph component. The flaw arises when decoding key material in process_auth_done(), where the code failed to enforce an upper bound on key length. The fix defines and enforces CEPH_MAX_KEY_LEN and clamps key material to a fixed-size buffer, addressing a v...

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 ceph asynchronous unlink operation reducing the inlink counter prematurely before it is...

CVE-2026-43420: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: 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 inlink because "we assume that the unlink will succeed". That is not a...
