Fedora 43 : nagios-plugins (2026-7ac5fb031f)

The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-7ac5fb031f advisory. Update to upstream bz2453492. checkicmp: host-count overflow leads to heap buffer overflow bz2513957 Update 0012-fix-perl-ntp-ipv6.patch to allow uppercase...

CVE-2026-89707

A flaw was found in the Linux kernel's nfsd component. An authenticated Network File System NFS client can exploit this vulnerability by triggering a failed cross-mount operation through nfsdlookupdentry or the NFSv4 READDIR encode path. This leads to a reference count leak, which inflates mntcou...

CVE-2026-89695

A flaw was found in the Linux kernel's Network File System Daemon nfsd. The nfsd4decodeposixacl function, responsible for decoding POSIX Access Control Lists ACLs, does not properly cap the entry count received from a client. A remote attacker can exploit this by sending a specially crafted ACL...

CVE-2026-89688

A flaw was found in the Linux kernel's nfsd component. During a seqidop replay retry, the system incorrectly handles reference counts for stateowners, leading to a reference count underflow and a use-after-free vulnerability. This issue could allow an attacker to potentially cause a denial of...

CVE-2026-80983

A flaw was found in the Linux kernel's implementation of the Server Message Block SMB over Remote Direct Memory Access RDMA protocol, specifically within the net/smc component. An error path in the smcswitchconns function, triggered during link failover events, can lead to a socket reference coun...

CVE-2026-89544

A flaw was found in the Linux kernel's SUNRPC component. Multiple defects in the gssxdecoptionarray XDR option-array decoder's error handling can lead to a NULL dereference, a reference count leak, and a use-after-free vulnerability. An attacker could potentially exploit these issues by providing...

CVE-2026-89593

A flaw was found in the Linux kernel's huge page hugetlb subsystem. This vulnerability occurs when a huge page of memory is shared between a parent and a child process. If the parent process unmaps the huge page before the child, the system can incorrectly reduce the count of reserved huge pages...

CVE-2026-89695

In the Linux kernel, the following vulnerability has been resolved: nfsd: cap decoded POSIX ACL count to bound sort cost nfsd4decodeposixacl reads a u32 entry count off the wire and passes it straight to posixaclalloc and sortpaclrange. The latter is an On^2 bubble sort, so a client-chosen count...
