CVE-2026-98266

The Linux kernel contains a use-after-free vulnerability in the ALSA core component. The issue occurs when a sound card is released asynchronously via snd_card_free_when_closed(), such as in USB-audio drivers . While snd_card_disconnect() gates new accesses, in-flight tasks may still access the u...

CVE-2026-98265

The Linux kernel contains a vulnerability in the ALSA usb-audio driver where the data_ep_set_params() function allocates data URB memory based on u->packets. However, for implicit feedback sinks, snd_usb_queue_pending_output_urbs() may overwrite this limit with a larger count from the sync sou...

CVE-2026-98264 ALSA: virtio: reset device before deleting virtqueues

In the Linux kernel, the following vulnerability has been resolved: ALSA: virtio: reset device before deleting virtqueues virtsndremove and virtsndfreeze delete the virtqueues before resetting the device. delvqs frees the vring backing, but does not provide a generic device quiesce operation. In...

CVE-2026-98264

The Linux kernel contains a vulnerability in the ALSA virtio driver where virtsnd_remove() and virtsnd_freeze() delete virtqueues before resetting the device. Because del_vqs() frees the vring backing without a generic device quiesce operation, modern virtio-pci may keep enabled queues active, po...

CVE-2026-98263

The Linux kernel contains a vulnerability in the ASoC: codecs: rt712-sdca-dmic component. The root cause is that the stream_config structure is not initialized before being passed to sdw_stream_add_slave() , allowing the type field to contain garbage values. This uninitialized data is subsequentl...

CVE-2026-98262 ata: libahci: clear PxCLBU and PxFBU for AHCI_HFLAG_32BIT_ONLY

CVE-2026-98262

The Linux kernel libahci driver contains a functional issue where the JMicron JMB585 becomes unusable when the AHCI_HFLAG_32BIT_ONLY flag is used. The root cause is that for HBAs supporting 64-bit addressing, the PxCLBU and PxFBU registers have implementation-specific reset values; however, when ...
