Linux Distros Unpatched Vulnerability : CVE-2026-23088

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tracing: Fix crash on synthetic stacktrace field usage When creating a synthetic event based on an existing synthetic event that had a stacktrace field and the...

CVE-2026-23088: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix crash on synthetic stacktrace field usage When creating a synthetic event based on an existing synthetic event that had a stacktrace field and the new synthetic event used that field a kernel crash occurred: cd...

CVE-2026-23041: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: bnxten: Fix NULL pointer crash in bnxtptpenable during error cleanup When bnxtinitone fails during initialization e.g., bnxtinitintmode returns -ENODEV, the error path calls bnxtfreehwrmresources which destroys the DMA pool and...

PT-2026-37464

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the pstore ram core component where the persistent ram vmap function may return a non-NULL pointer even when vmap fails, provided the offset is non-zero. This occurs...

kernel: mptcp: fix race condition in mptcp_schedule_work()

A race in mptcpschedulework could lead to a use-after-free: the function queued work and only then acquired a reference to the socket. If the worker ran to completion immediately, the subsequent sockhold operated on a freed object. Impact ranges from kernel crash DoS to potential privilege...

kernel: Linux kernel: Denial of Service in ATM CLIP module via infinite recursion

A flaw was found in the Linux kernel's Asynchronous Transfer Mode ATM Classical IP CLIP module. A local user can trigger an infinite recursive call in the clippush function by repeatedly calling the ioctlATMARPMKIP system call. This vulnerability occurs when the socket is closed, leading to stack...

Linux Kernel Security Vulnerabilities

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 improper handling of inittask errors, and could potentially lead to a kernel crash...

CVE-2026-23017: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: idpf: fix error handling in the inittask on load If the inittask fails during a driver load, we end up without vports and netdevs, effectively failing the entire process. In that state a subsequent reset will result in a crash as...

CVE-2026-23019: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: net: marvell: prestera: fix NULL dereference on devlinkalloc failure devlinkalloc may return NULL on allocation failure, but presteradevlinkalloc unconditionally calls devlinkpriv on the returned pointer. This leads to a NULL...

kernel: Linux kernel (CIFS): Use-after-free vulnerability allows data integrity compromise and denial of service

A flaw was found in the Linux kernel's Common Internet File System CIFS component. This use-after-free vulnerability occurs due to improper handling of server hostname information during connection re-establishment. An attacker on an adjacent network could exploit this, potentially leading to a...
