CVE-2024-39508

CVE-2024-39508 affects the Linux kernel’s io_uring io-wq path. The advisory details data-race issues on io_worker->flags exposed under concurrency (io_worker_handle_work and io_wq_activate_free_worker) and shows that the fix refactors flag manipulation to atomic operations using set_bit() and ...

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 a potential data contention issue in the iouring/io-wq component when handling worker threads...

The vulnerability of the idxd_wq_del_cdev() function in the drivers/dma/idxd/cdev.c file of the Linux operating system allows a hacker to gain increased privileges.

The vulnerability of the idxdwqdelcdev function in the drivers/dma/idxd/cdev.c file of Linux operating systems is related to the possibility of using memory after it is freed. Exploiting this vulnerability can allow an attacker to increase their privileges...
