CVE-2026-43366

A flaw was found in the Linux kernel. A vulnerability exists in the iouring/kbuf component related to buffer recycling. There is a time gap where a buffer list, if empty, could be incorrectly upgraded to a ring-provided type. The legacy recycling mechanism fails to properly check the buffer list'...

CVE-2026-43353

A flaw was found in the Linux kernel's i3c: mipi-i3c-hci module. A race condition in the hcidmadequeuexfer function allows parallel calls to interfere with each other when multiple transfers time out concurrently. This interference can cause the DMA ring to stop or restart unexpectedly, potential...

CVE-2026-43352

A flaw was found in the Linux kernel's I3C Improved Inter-Integrated Circuit Host Controller Interface HCI driver. Incorrect handling of DMA Direct Memory Access ring aborts can lead to the unintentional clearing of RINGCTRLENABLE. This action resets hardware ring pointers and disrupts the...

CVE-2026-43345

A flaw was found in the Linux kernel's ipa driver. This vulnerability, affecting IPA version 5.0 and later, stems from an incorrect event ring index programming, preventing GSI channels from signaling transfer completions. As a result, the system can experience hangs during operations such as...

EUVD-2026-28677

In the Linux kernel, the following vulnerability has been resolved: net: macb: Shuffle the tx ring before enabling tx Quanyang observed that when using an NFS rootfs on an AMD ZynqMp board, the rootfs may take an extended time to recover after a suspend. Upon investigation, it was determined that...

EUVD-2026-28658

In the Linux kernel, the following vulnerability has been resolved: i3c: mipi-i3c-hci: Correct RINGCTRLABORT handling in DMA dequeue The logic used to abort the DMA ring contains several flaws: 1. The driver unconditionally issues a ring abort even when the ring has already stopped. 2. The...

EUVD-2026-28629

In the Linux kernel, the following vulnerability has been resolved: net: ipa: fix event ring index not programmed for IPA v5.0+ For IPA v5.0+, the event ring index field moved from CHCCNTXT0 to CHCCNTXT1. The v5.0 register definition intended to define this field in the CHCCNTXT1 fmask array but...

CVE-2026-43371

The CVE-2026-43371 details the Linux kernel macb driver fault where disabling transmit resets tx_head/tx_tail to 0, causing silent loss of queued packets, memory leaks, and race conditions between macb_tx_poll() and macb_start_xmit(). This can prolong recovery after suspend (e.g., NFS rootfs on A...
