CVE-2026-99252
A flaw was found in the Linux kernel's iouring subsystem. A local user can trigger a Denial of Service DoS condition due to missing preemption protection during internal queue updates. When a lower-priority task updating a queue is interrupted by a higher-priority task on the same processor core,...

CVE-2026-99252
The Linux kernel contains a vulnerability in the io_uring/mpscq component where a producer task can be preempted between making a node the new tail and linking it to its predecessor. If a high-priority consumer (e.g., SCHED_FIFO ) runs on the same CPU as a lower-priority producer (e.g., SCHED_OTH...

Google Cloud Run MCP encryption issue vulnerability
Versions of Google Cloud Run MCP prior to 1.11.0 contain an encryption-related vulnerability stemming from bucket preemption. This may allow attackers to intercept and access proprietary source code, execute arbitrary code, and exfiltrate data...
CVE-2026-94024
The Module Manager's object lookup validated one byte of a memory-protected module's search name and then walked as much of it as the module declared, in privileged mode, with the kernel's preemption count raised. Both lookup dispatchers are affected: the recommended...

CVE-2026-94024
The Module Manager in the affected software suffers from an out-of-bounds read (CWE-125) and improper validation of specified quantity (CWE-1284) during object lookups. The vulnerability exists because the manager validates only one byte of a memory-protected module's search name before performin...

In the Linux kernel, the following vulnerability has been resolved: schedext: Disable preemption between scxclaimexit and kicking helper work scxclaimexit atomically sets exitkind, which prevents scxerror from triggering further error handling. After claiming exit, the caller must kick the helper...
Linux Kernel Security Vulnerabilities
The Linux kernel has a security vulnerability. This vulnerability arises from the ineffective use of condresched in the PREEMPTION kernel during offline cgwb cleanup. This failure does not report the quiescent state of Tasks-RCU, which may lead to prolonged blocking of synchronizercutasks and...
