In the Linux kernel, the following vulnerability has been resolved: isofs: validate block number from NFS file handle in isofsexportiget isofsfhtodentry and isofsfhtoparent pass an attacker- controlled block number ifid-block or ifid-parentblock from the NFS file handle to isofsexportiget, which...

CVE-2026-46123

Summary: CVE-2026-46123 affects the Linux kernel Bluetooth virtio_bt driver. The issue arises when virtbt_rx_work() skb_put(skb, len) uses an unvalidated len sourced from virtqueue_get_buf(), with the device exposing a 1000-byte RX buffer. Since alloc_skb() tailroom can exceed 1000, a malicious/b...

In the Linux kernel, the following vulnerability has been resolved: block: add pgmap check to biovecphysmergeable biovecphysmergeable is used by the request merge, DMA mapping, and integrity merge paths to decide if two physically contiguous bvec segments can be coalesced into one. It currently h...

CVE-2026-46115

In the Linux kernel block subsystem, CVE-2026-46115 was addressed by adding a check so that zone_device_pages_have_same_pgmap() prevents merging bvec segments that span different dev_pagemaps in biovec_phys_mergeable. Root cause: biovec_phys_mergeable() did not verify that two physically contiguo...

CVE-2026-4377 Use of Weak Credentials in D-Link DWR-X1820 router

Dlink DWR-X1820 router uses weak default password generated from its IMEI number and does not require users to change it. An attacker who knows how passwords are generated can easily crack the default password if they have the device IMEI number. This issue was fixed in version 1.00B16CP...

CVE-2026-4377

The CVE refers to the D-Link DWR-X1820 router, where a weak default password is generated from the IMEI and does not require change by the user. This vulnerability can allow an attacker who knows the password-generation method to crack the default password given the device IMEI. A fix is availabl...
