Linux Distros Unpatched Vulnerability : CVE-2026-46193

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - xfrm: ah: account for ESN high bits in async callbacks AH allocates its temporary auth/ICV layout differently when ESN is enabled: the async ahash setup appends...

CVE-2026-46193

A flaw was found in the Linux kernel's xfrm: ah component, which handles network security protocols. When Extended Sequence Number ESN is active, the kernel incorrectly processes parts of network packet data during security checks. This error can lead to the system dropping legitimate network...

SUSE CVE-2026-45894

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clear Present bit before tearing down PASID entry The Intel VT-d Scalable Mode PASID table entry consists of 512 bits 64 bytes. When tearing down an entry, the current implementation zeros the entire 64-byte structure...

SUSE CVE-2026-45983

In the Linux kernel, the following vulnerability has been resolved: nfsd: never defer requests during idmap lookup During v4 request compound arg decoding, some ops e.g. SETATTR can trigger idmap lookup upcalls. When those upcall responses get delayed beyond the allowed time limit, cachecheck wil...

PT-2026-44316

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the xfrm AH implementation where the system fails to account for Extended Sequence Number ESN high bits in asynchronous callbacks. When ESN is enabled, the asynchronou...

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 fact that the high ESN value in the xfrm AH is not properly considered during asynchronous...

CVE-2026-45983

In CVE-2026-45983, the Linux kernel NFS server (nfsd) vulnerability stems from idmap lookup upcalls during v4 request decoding: if upcall responses are delayed beyond the time limit, cache_check() postpones the request and it gets dropped, causing NFSD4_SLOT_INUSE to block subsequent SEQUENCE ope...

CVE-2026-45894

The CVE-2026-45894 issue affects the Linux kernel IOMMU VT-d Scalable Mode PASID handling. When a PASID table entry is torn down, the current code zeros the full 64-byte structure while P=1, risking a torn read if hardware fetches the 64 bytes concurrently. Mitigation directs an ownership handsha...
