CVE-2026-80685

A flaw was found in the Linux kernel's memory management subsystem. The snapshotpage function attempts to read memory that may not exist when handling certain memory structures order-1 folios during specific memory operations, such as dynamic logical partitioning DLPAR memory removal. This...

CVE-2026-80685

In the Linux kernel, the following vulnerability has been resolved: mm/util: don't read page2 for order-1 folios in snapshotpage snapshotpage currently reads page2 after checking nrpages 1, but it should only do so when nrpages 2. If an order-1 folio is allocated at the end of a vmemmap section,...

CVE-2026-80685

A Linux kernel vulnerability in the snapshot_page() function within mm/util causes an out-of-bounds read of the __page_2 field for order-1 folios allocated at the end of a vmemmap section . The function incorrectly reads __page_2 when nr_pages > 1, but should only do so when nr_pages > 2; s...

kernel: powerpc: Fix access beyond end of drmem array

A flaw was found in the Linux kernel, specifically affecting the PowerPC architecture's pseries memory hotplug functionality. The issue arises from the dlparmemoryremovebyindex function, which may access memory beyond the bounds of the drmem logical memory block LMB array when it fails to find a...

The vulnerability of the dlpar_memory_remove_by_index() function in the Linux operating system’s PowerPC PSeries kernel driver allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the dlparmemoryremovebyindex function in the Linux operating system’s PowerPC PSeries kernel memory driver relates to reading memory beyond the allocated buffer. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

SUSE CVE-2023-52451

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries/memhp: Fix access beyond end of drmem array dlparmemoryremovebyindex may access beyond the bounds of the drmem lmb array when the LMB lookup fails to match an entry with the given DRC index. When the search fails,...
