Linux Distros Unpatched Vulnerability : CVE-2026-89497

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - orangefs: skip leading spaces before parsing client debug masks orangefspreparecdmarray sizes each client debug keyword buffer with strcspncdshead, , but then...

CVE-2026-89662

A flaw was found in the Linux kernel's Network File System Daemon NFSD. During client teardown, a race condition can occur where a lock owner is freed while still being referenced, leading to a use-after-free vulnerability. This can result in a NULL dereference, potentially causing a system crash...

CVE-2026-89632

A flaw was found in the Linux kernel's Server Message Block SMB client. A malicious server could exploit this vulnerability by sending specially crafted data, leading to an out-of-bounds read. This occurs because the reparsebufptr function reads data before properly validating the buffer size,...

CVE-2026-89696

A flaw was found in the Linux kernel's Network File System NFS daemon nfsd. A remote client can exploit this by sending a specially crafted NFS COMPOUND request. This request, when processed, can lead to a NULL pointer dereference in the nfsd kthread, causing the system to crash and resulting in ...

CVE-2026-89637

A flaw was found in the Linux kernel's Server Message Block SMB client. When processing a malformed secondary TRANSACT2 response, a use-after-free UAF vulnerability and a buffer leak can occur in the cifschecktrans2 function. This can lead to a dangling buffer being reused by the demux thread,...

CVE-2026-89636

A flaw was found in the Linux kernel's Server Message Block SMB client. When the freetgts function frees data structures, a pointer ce-tgthint is not properly reset, leaving it pointing to a memory location that has already been deallocated. If this pointer is subsequently used, it can lead to a...

CVE-2026-89536

A flaw was found in the Linux kernel's SUNRPC Sun Remote Procedure Call client TLS Transport Layer Security handshake process. A race condition exists where a reference to the lower transport can be prematurely released during handshake cancellation. This can lead to memory corruption, potentiall...

CVE-2026-89651

A flaw was found in the Linux kernel's Ceph client. An out-of-bounds read vulnerability exists in the handlesession function when decoding MDSCapAuth records. A malicious or compromised Metadata Server MDS can trigger this during session setup without client-side user interaction. This can force...

CVE-2026-90455

A prior update that raised a bundled HTTP client library to a version remediating known vulnerabilities was later reverted, reintroducing the earlier, vulnerable version into a log-processing component. The only code path in that component using the library issues a request to a single fixed,...

CVE-2026-89698

A flaw was found in the Linux kernel's nfsd component. When an IPv6 NFS client is connected, the nfsdgenlrpcstatuscomposemsg function incorrectly handles address fields, leading to an out-of-bounds read. A local unprivileged attacker can exploit this vulnerability to disclose sensitive kernel...

CVE-2026-89633

A flaw was found in the Linux kernel's Server Message Block SMB client. The coalescet2 function processes server-supplied DataOffset fields without proper validation against buffer boundaries. A remote attacker could exploit this by crafting malicious SMB responses. This could lead to out-of-boun...

CVE-2026-90455

This vulnerability involves a reverted update to a bundled HTTP client library within a log-processing component , reintroducing a previously vulnerable version. The root cause is that a prior patch raising the library to a fixed version was undone, restoring the vulnerable code. However, the onl...

CVE-2026-90447

This ICS-CERT advisory (CSAF reference: ICSA-26-254-01) describes a privilege escalation vulnerability in a downstream service where a routing rule selects between two authentication mechanisms based on a client-supplied request header . An authenticated user possessing a shared service credentia...

CVE-2026-90447 Authentication Bypass by Spoofing in Malcolm

A routing rule selects between two different authentication mechanisms for the same downstream service based on the value of a client-supplied request header, rather than on any property the client cannot control. An authenticated user in possession of a shared service credential can set this...

CVE-2026-89638

A flaw was found in the Linux kernel's Server Message Block SMB client. When a file with the setuid or setgid bit is written to on certain Common Internet File System CIFS mounts specifically those using 'cifsacl', 'modefromsid' options, or SMB3.1.1 POSIX extensions, the kernel fails to properly...
