kernel: Linux kernel: Denial of Service in DRM scheduler due to improper work queue handling

A flaw was found in the Linux kernel's Direct Rendering Manager DRM scheduler. A local attacker with low privileges could exploit this vulnerability by triggering a GPU reset test. This improper handling of the scheduler work queue can lead to a kernel panic, which is a system crash, resulting in...

kernel: blk-mq: release crypto keyslot before reporting I/O complete

A flaw was identified in the block multi-queue blk-mq subsystem of the Linux kernel where the crypto keyslot associated with a block I/O request could be released after upper layers have been notified that the I/O operation completed. Under certain conditions, this could lead to a use-after-free ...

kernel: refscale: Fix uninitalized use of wait_queue_head_t

A use of uninitialized data was found in the refscale test module. The waitqueueheadt is used before being initialized, causing a race condition that can crash the kernel during testing...

kernel: netfilter: nf_tables: reject QUEUE/DROP verdict parameters

REJECTED CVE An issue was identified in the Linux kernel's netfilter subsystem related to nftables. The issue occurs when a positive value, such as NFACCEPT, is provided in the upper 16 bits of NFDROP verdict parameters, which are expected to contain valid errno values e.g., -EPERM. This improper...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the fact that allocating fewer queues than traffic classes can cause the kernel to crash...

IBM MQ Appliance security vulnerabilities

The IBM MQ Appliance is an all-in-one appliance for rapid deployment of enterprise-class messaging middleware. The IBM MQ Appliance suffers from a buffer overflow vulnerability that originates from not properly checking boundaries, which can be exploited by an attacker to overflow a buffer and...

kernel: use after free in unix_stream_sendpage

A use-after-free flaw was found in the Linux kernel's afunix component that allows local privilege escalation. The unixstreamsendpage function tries to add data to the last skb in the peer's recv queue without locking the queue. This issue leads to a race condition where the unixstreamsendpage...

WDAC OLE DB Driver Code Execution
