Linux kernel 安全漏洞

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 possibility of dividing by zero when calculating costs for non-CPU devices...

kernel: blk-iocost: use spin_lock_irqsave in adjust_inuse_and_calc_cost

In the Linux kernel, the following vulnerability has been resolved: blk-iocost: use spinlockirqsave in adjustinuseandcalccost adjustinuseandcalccost use spinlockirq and IRQ will be enabled when unlock. DEADLOCK might happen if we have held other locks and disabled IRQ before invoking it. Fix it b...

Calculating project cost is vulnerable to reaching block gas-limit

Lines of code Vulnerability details Impact The function Project.projectCost calculates the project costs by calculating the sum of all project task costs. However, due to the unbound for loop, iterating over a potentially large amount of project tasks, this function can potentially DoS due to...

The vulnerability of Schneider Electric CanBrass software for designing and calculating the cost of hose pipelines lies in the fact that operations can be executed outside the buffer in memory, allowing an attacker to execute arbitrary code.

The vulnerability of Schneider Electric CanBrass’s software for designing and calculating hose pipe costs is related to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability could allow an attacker to execute arbitrary code...
