CVE-2024-40945 iommu: Return right value in iommu_sva_bind_device()

In the Linux kernel, the following vulnerability has been resolved: iommu: Return right value in iommusvabinddevice iommusvabinddevice should return either a sva bond handle or an ERRPTR value in error cases. Existing drivers idxd and uacce only check the return value with ISERR. This could...

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 possible post-release reuse of the dmaengine:idxd component in irqprocessworklist...

PT-2024-29750

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.43 Description The issue arises from the idxd driver interrupt completion handler using threaded interrupt, which is not compatible with the hard or soft interrupt context required by netif rx. To resolve thi...

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...

CVE-2024-38629

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Avoid unnecessary destruction of fileida fileida is allocated during cdev open and is freed accordingly during cdev release. This sequence is guaranteed by driver file operations. Therefore, there is no need to...

CVE-2024-38629

In CVE-2024-38629, the Linux kernel’s dmaengine: idxd driver had a use-after-free risk where ida_destroy(&file_ida) could run after file_ida was already destroyed during WQ cdev teardown, risking a kernel panic. The fix removes ida_destroy(&file_ida) since file_ida is allocated on cdev open and f...
