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-2026-31436

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...

CVE-2026-31443

CVE-2026-31443 : Linux kernel, dmaengine: idxd driver fix. When hardware does not support event logging and a Function Level Reset (FLR) occurs, the driver previously attempted to restore the event log even if it was never allocated, and may crash. The fix ensures the event log is only freed if i...

CVE-2026-31441

CVE-2026-31441 affects the Linux kernel in the dmaengine: idxd component, where a memory leak occurs on workqueue reset. Root cause: idxd_wq_disable_cleanup() resets the wq type to NONE before resources are released. The upstream patch fixes the leak by ensuring resources are released before clea...

CVE-2026-31441 dmaengine: idxd: Fix memory leak when a wq is reset

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...

CVE-2026-31442 dmaengine: idxd: Fix possible invalid memory access after FLR

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...

CVE-2026-31440

CVE-2026-31440 affects the Linux kernel’s dmaengine idxd driver. The issue arises during device removal when a reset clears configuration registers, causing the prior check for event log support to fail if evl is no longer valid. The propagated fixes remove the check for “evl” enabled state and i...

CVE-2026-31440 dmaengine: idxd: Fix leaking event log memory

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...

CVE-2026-31436

Summary of CVE-2026-31436 : The Linux kernel’s dmaengine idxd driver contains a bug in the llist_abort_desc() function where the code completes the wrong descriptor (the variable “found” rather than the traversal cursor “d”) as the function unwinds a doubly linked list. This can lead to NULL poin...
