Improper locking in Linux kernel - CVE-2024-35991

Vulnerability identifier: #VU91445

CSH Severity: Low

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2024-35991

CWE-ID: CWE-667

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper locking within the process_evl_entries() function in drivers/dma/idxd/irq.c, within the idxd_init_evl() function in drivers/dma/idxd/init.c, within the idxd_device_evl_setup() and idxd_device_evl_free() functions in drivers/dma/idxd/device.c, within the debugfs_evl_show() function in drivers/dma/idxd/debugfs.c, within the idxd_cdev_evl_drain_pasid() function in drivers/dma/idxd/cdev.c. A local user can perform a denial of service (DoS) attack.
