CVE-2026-63972

A flaw was found in the Linux kernel's mana network driver. An issue arises when the driver attempts a redundant detach operation on an already-detached network port. This can cause a null pointer dereference, leading to a system crash and a Denial of Service DoS...

SUSE CVE-2026-63973

In the Linux kernel, the following vulnerability has been resolved: net: mana: Add NULL guards in teardown path to prevent panic on attach failure When queue allocation fails partway through, the error cleanup frees and NULLs apc-txqp and apc-rxqs. Multiple teardown paths such as manaremove,...

SUSE CVE-2026-64018

In the Linux kernel, the following vulnerability has been resolved: net: mana: validate rxreqidx to prevent out-of-bounds array access In manahwcrxeventhandler, rxreqidx is derived from sge-address in DMA-coherent memory. In Confidential VMs SEV-SNP/TDX, this memory is shared unencrypted and HW c...

CVE-2026-63973

A flaw was found in the Linux kernel's mana network driver. During certain error handling scenarios, specifically when network queue allocation fails, the driver attempts to access memory that has already been freed. This can lead to a NULL pointer dereference, causing the system to crash and...
