CVE-2026-63962

In the Linux kernel, the following vulnerability has been resolved: usb: typec: tcpm: bound altmodedesc per iteration in svdmconsumemodes svdmconsumemodes checks pmdata-altmodes against the array size once before the loop over the count, but forgot to check the bound at every point in the loop. I...

CVE-2026-63962

The CVE-2026-63962 entry describes a Linux kernel vulnerability in usb: typec: tcpm: bound altmode_desc[] per iteration in svdm_consume_modes(). The root cause is that svdm_consume_modes() checked pmdata->altmodes against the array size only once before looping over the count, not at every ite...

CVE-2026-63942 parport: Fix race between port and client registration

In the Linux kernel, the following vulnerability has been resolved: parport: Fix race between port and client registration The parport subsystem registers port devices before they are fully initialised, resulting in a race condition where client drivers such as lp can attach to ports that are not...

EUVD-2026-45672

In the Linux kernel, the following vulnerability has been resolved: USB: serial: mxuport: fix memory corruption with small endpoint Make sure that the bulk-out endpoint max packet size is at least eight bytes to avoid user-controlled slab corruption should a malicious device report a smaller size...

CVE-2026-63899

CVE-2026-63899 concerns a memory corruption in Linux kernel USB serial mxuport implementation. The vulnerability arises when handling the bulk-out endpoint where the maximum packet size could be smaller than safe, enabling user-controlled slab corruption if a malicious USB device reports a small ...

CVE-2026-63877 serial: dz: Convert to use a platform device

In the Linux kernel, the following vulnerability has been resolved: serial: dz: Convert to use a platform device Prevent a crash from happening as the first serial port is initialised: Console: switching to colour frame buffer device 160x64 tgafb: SFB+ detected, rev=0x02 fb0: Digital ZLX-E1 frame...

CVE-2026-63877

The CVE-2026-63877 entry concerns the Linux kernel DZ serial driver (serial: dz) and its transition from legacy probing to a platform device model. A null-pointer dereference occurred when the first serial port was initialized, caused by using a port parent device that could be derived from a nul...
