SUSE CVE-2026-31398

In the Linux kernel, the following vulnerability has been resolved: mm/rmap: fix incorrect pte restoration for lazyfree folios We batch unmap anonymous lazyfree folios by foliounmapptebatch. If the batch has a mix of writable and non-writable bits, we may end up setting the entire batch writable...

CVE-2026-31398

A flaw was found in the Linux kernel's memory management unit MMU. A local user could exploit this vulnerability by manipulating memory operations, leading to incorrect page table entry PTE restoration for lazyfree folios during batch unmapping. This issue can cause memory pages with mixed writab...

CVE-2026-23432

A flaw was found in the Linux kernel's mshv component. A local user could exploit a use-after-free vulnerability by unmapping memory after a specific error path in the mshvmapusermemory function. This can cause a system crash kernel panic due to the system attempting to access freed memory...

The vulnerability of the fastrpc_req_mem_unmap_impl() function in the drivers/misc/fastrpc.c module of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the fastrpcreqmemunmapimpl function in the drivers/misc/fastrpc.c module of the Linux operating system is related to improper cleaning or release of resources. Exploiting this vulnerability can allow an attacker to cause a service failure...

CVE-2026-23289

A flaw was found in the Linux kernel's IB/mthca component. A local user could exploit this vulnerability by triggering a system call failure path related to the mthcacreatesrq function. This oversight leads to a missed unmapping of user database resources, resulting in a resource leak...
