Linux Distros Unpatched Vulnerability : CVE-2026-89489

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - openrisc: fix arbitrary kernel memory access via or1katomic syscall sysor1katomic syscall 244 in the or1k ABI takes two user pointers, v1 and v2, and swaps the...

CVE-2026-89743

A flaw was found in the Linux kernel's Network Shared Memory NSM component. A malicious or buggy backend can report a response length larger than the allocated buffer. This can lead to an out-of-bounds read, disclosing adjacent kernel memory to user space. This vulnerability results in informatio...

CVE-2026-89628

A flaw was found in the Human Interface Device HID picolcd driver in the Linux kernel. A local attacker with root privileges, by using a specially crafted or spoofed picoLCD device, could exploit an out-of-bounds read vulnerability in the picolcddebugeepromread function. This flaw occurs because...

CVE-2026-80946

A flaw was found in the Linux kernel's FUSE Filesystem in Userspace component. The io-uring transport attempts to copy request headers directly to or from user space without proper memory validation. A local attacker could exploit this vulnerability, leading to a kernel panic and a denial of...

CVE-2026-89631

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote malicious SMB server could send a specially crafted tree connect response with a byte count that is too small. This incorrect handling can lead to an integer underflow, causing the client to read beyond an allocated...

CVE-2026-89489

A flaw was found in the Linux kernel. The sysor1katomic syscall, specific to the openrisc architecture, does not adequately validate user-provided pointers. An unprivileged process can exploit this by supplying kernel addresses to the syscall, gaining unauthorized read and write access to kernel...

CVE-2026-80973

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture subsystem, specifically within the 6fire driver. This vulnerability allows a malicious USB device to trigger an out-of-bounds read by sending a specially crafted MIDI event with an excessive length. This can lead to the...

CVE-2026-89714

In the Linux kernel, the following vulnerability has been resolved: NFS: fix delegationhashtable leak when nfs4servercommonsetup fails nfs4servercommonsetup allocates server-delegationhashtable first, but server-destroy - the only path that frees the table via nfs4destroyserver - is not assigned...
