CVE-2026-74632
A flaw was found in the Linux kernel's memory management mm/hugememory. A race condition can occur between a memory shrinker and a concurrent page fault when handling huge zero pages. This race can lead to the hugezeropfn being incorrectly set, causing the huge zero page to be misidentified as an...
Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: block: fixed a memory leak in blkdevissuezeropages. The check for the fatal signal was moved before the bioalloc function, thereby preventing a memory leak when BLKDEVZEROKILLABLE is set and a fatal signal is pending. Previously,...
CVE-2026-31397
A flaw was found in the Linux kernel's memory management subsystem, specifically within the movepageshugepmd function. A local user could exploit a NULL pointer dereference when handling huge zero pages, which can lead to a system crash and a Denial of Service DoS. Furthermore, improper...
CVE-2026-31397
CVE-2026-31397 relates to the Linux kernel memory management path mm/huge_memory move_pages_huge_pmd(), where the huge zero page branch used a NULL src_folio, causing a bogus PFN (or NULL dereference on some memory models) when constructing PMDs. The fix uses page_folio(src_page) to obtain a vali...

CVE-2026-31397: NULL Pointer Dereference
In the Linux kernel, the following vulnerability has been resolved: mm/hugememory: fix use of NULL folio in movepageshugepmd movepageshugepmd handles UFFDIOMOVE for both normal THPs and huge zero pages. For the huge zero page path, srcfolio is explicitly set to NULL, and is used as a sentinel to...
The vulnerability of the __blkdev_issue_zero_pages() function in the block/blk-lib.c module, which is part of the Linux kernel’s block-level support, allows a hacker to trigger a service failure.
The vulnerability of the blkdevissuezeropages function in the block/blk-lib.c module, which supports the block-level kernel in the Linux operating system, is related to improper memory release memory leak. Exploiting this vulnerability could allow an attacker to cause a service failure...
