UBUNTU-CVE-2026-46091

In the Linux kernel, the following vulnerability has been resolved: media: rc: igorplugusb: heed coherency rules In a control request, the USB request structure can be subject to DMA on some HCs. Hence it must obey the rules for DMA coherency. Allocate it separately...

UBUNTU-CVE-2026-46103

In the Linux kernel, the following vulnerability has been resolved: can: ucan: fix devres lifetime USB drivers bind to USB interfaces and any device managed resources should have their lifetime tied to the interface rather than parent USB device. This avoids issues like memory leaks when drivers...

UBUNTU-CVE-2026-45865

In the Linux kernel, the following vulnerability has been resolved: mctp i2c: initialise event handler read bytes Set a 0xff value for i2c reads of an mctp-i2c device. Otherwise reads will return "val" from the i2c bus driver. For i2c-aspeed and i2c-npcm7xx that is a stack uninitialised u8. Teste...

CVE-2026-23679 libusb < 1.0.30 NULL Pointer Dereference in parse_interface()

libusb before version 1.0.30 contains a NULL pointer dereference vulnerability that allows attackers to crash applications by supplying a malformed USB configuration descriptor where an interface claims bNumEndpoints greater than zero but is followed by a class-specific descriptor whose bLength...

EUVD-2026-32500

libusb before version 1.0.30 contains a one-byte out-of-bounds read vulnerability in parseiadarray in descriptor.c that allows attackers to trigger a denial of service by supplying a malformed USB descriptor whose bLength equals size minus one, causing the bounds check to use the original buffer...

CVE-2026-46092

CVE-2026-46092 relates to the Linux kernel's wifi rtw88 driver (8821CE) where pci_upstream_bridge() returns NULL for devices on a root bus, risking a crash during probe on certain PCI topologies. The fix is to explicitly check for the PCI upstream bridge before applying the workaround. A patch wa...
