A Use-After-Free UAF is a memory corruption vulnerability tha...

CVE-2026-53295

A flaw was found in the Linux kernel's mailbox component. This vulnerability arises from an insufficient sanity check for the channel array. When a mailbox controller is initialized without an attached channel array, a subsequent operation can lead to a null pointer dereference, causing a kernel...

CVE-2026-53294

A flaw was found in the Linux kernel's mailbox subsystem. This vulnerability occurs when the receive RX channel is aliased to the transmit TX channel with a different Memory-Mapped I/O MMIO and is not properly handled during the freeing of channels. This can lead to a double-free condition, which...
