SUSE CVE-2026-31436

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix possible wrong descriptor completion in llistabortdesc At the end of this function, d is the traversal cursor of flist, but the code completes found instead. This can lead to issues such as NULL pointer...

SUSE CVE-2026-31439

In the Linux kernel, the following vulnerability has been resolved: dmaengine: xilinx: xdma: Fix regmap init error handling devmregmapinitmmio returns an ERRPTR upon error, not NULL. Fix the error check and also fix the error message. Use the error code from ERRPTR instead of the wrong value in r...

SUSE CVE-2026-31441

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix memory leak when a wq is reset idxdwqdisablecleanup which is called from the reset path for a workqueue, sets the wq type to NONE, which for other parts of the driver mean that the wq is empty all its resourc...

SUSE CVE-2026-31442

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix possible invalid memory access after FLR In the case that the first Function Level Reset FLR concludes correctly, but in the second FLR the scratch area for the saved configuration cannot be allocated, it's...

SUSE CVE-2026-31443

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix crash when the event log is disabled If reporting errors to the event log is not supported by the hardware, and an error that causes Function Level Reset FLR is received, the driver will try to restore the...

CVE-2026-31443

A flaw was found in the Linux kernel's dmaengine: idxd driver. When hardware does not support event logging and an error triggers a Function Level Reset FLR, the driver attempts to restore or free an event log that was never allocated. This improper handling can lead to a system crash, resulting ...

CVE-2026-31442

A flaw was found in the Linux kernel's dmaengine: idxd component. During a Function Level Reset FLR, if the system fails to allocate the scratch area for saved configuration after a successful initial reset, it can lead to an invalid memory access. This vulnerability could result in system...

CVE-2026-31441

A flaw was found in the Linux kernel's dmaengine: idxd module. This vulnerability occurs when a workqueue is reset, specifically within the idxdwqdisablecleanup function. The function prematurely sets the workqueue type to NONE before all associated resources are released, leading to a memory lea...

CVE-2026-31436

A flaw was found in the Linux kernel's dmaengine subsystem, specifically within the idxd driver. This vulnerability occurs due to incorrect descriptor completion in the llistabortdesc function. This can lead to issues such as NULL pointer dereferences, double completion, or descriptor leaks, whic...

EUVD-2026-24768

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix leaking event log memory During the device remove process, the device is reset, causing the configuration registers to go back to their default state, which is zero. As the driver is checking if the event log...

EUVD-2026-24772

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix possible invalid memory access after FLR In the case that the first Function Level Reset FLR concludes correctly, but in the second FLR the scratch area for the saved configuration cannot be allocated, it's...
