CVE-2026-90335: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: tty: skip cdevdel when no cdev is registered TTY device registration can fail before a cdev is allocated. Serial core keeps the port so setserial can still use it, and later removal passes the NULL cdev slot to cdevdel, causing a...

PT-2026-94683

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A NULL-pointer dereference occurs during TTY device removal. This happens when TTY device registration fails before a cdev is allocated, but the serial core retains the port for use by...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability that stems from the failure to check the allocation of pgdat-percpunodestats, which may lead to null pointer dereferencing...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 5.3. It arises when the drm/v3d driver fails to clear queue-activejob after calling v3dfencecreate within the runjob callback; this may result in a null pointer...

In the Linux kernel, the following vulnerability has been resolved: ACPI: PCI: Clear driverdata on all paths that free the acpipciroot acpipcirootadd assigns the freshly allocated root to device-driverdata before dmardeviceadd and pciacpiscanroot. Both failure paths reach the end: label where roo...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from the amdgpudmcrtcresetstate function, which releases the old state before allocating a new one. If the kzalloc function fails and returns, the state pointer is not updated, leaving a dangling pointer pointing to freed...
