Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: ALSA: usx2y: Do not call freepagesexact with a NULL address. Unlike some other functions, we cannot pass a NULL pointer to freepagesexact. Add a proper NULL check to avoid potential errors...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: In the mm/pagealloc function, the clearpage-private operation is performed in freepagesprepare. Several subsystems slub, shmem, ttm, etc. use page-private, but they do not clear it before freeing pages. When these pages are later...

PT-2026-94843

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the bpf arena free pages function where scalar arena addresses are processed by masking the address to the low 32 bits and reconstructing a full user address from the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: mm: vmscan: accounts for free pages to prevent infinite loops in throttledirectreclaim. The task sometimes continues looping in throttledirectreclaim because allowdirectreclaimpgdat keeps returning false. The stack trace is as...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: mm: pagealloc: moving the mlocked flag to freepagesprepare Syzbot reported a problem with bad page state caused by a page being freed using freepage, while the mlocked flag is still present during the freepagesprepare stage: BUG:...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: tee: amdtee: fixed an issue where ISERR returned NULL instead of an error pointer. The getfreepages function no longer returns error pointers; it now returns NULL. Therefore, this condition needs to be corrected to prevent NUL...

Unity Linux 20.1050a Security Update: kernel (UTSA-2026-053206)

"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-053206 advisory. In the Linux kernel, the following vulnerability has been resolved: Fix page corruption caused by racy check in freepages When we upgraded our kernel, we started...

FreeBSD Security Advisory - FreeBSD-SA-26:37.vm

FreeBSD Security Advisory - When msyncMSINVALIDATE is called on a mapping of an unmanaged device object, the physical pages in the mapping range are marked invalid but remain in the pager's page list. A subsequent page fault will cause the fault handler to re-insert the page into the object's lis...

kernel: mm/page_alloc: clear page->private in free_pages_prepare()

A flaw was found in the Linux kernel's memory management subsystem. When pages are freed, the page-private field is not properly cleared. If these pages are later reallocated as high-order pages and split, the tail pages can retain stale page-private values. This can lead to a use-after-free...

CVE-2026-46068

CVE-2026-46068 affects the Linux kernel's crypto nx path: bounce buffers allocated with _get_free_pages() (BOUNCE_BUFFER_ORDER) are freed with free_page() instead of free_pages(), causing memory leaks. The fix uses free_pages() with the matching order in nx842_crypto {alloc,free}_ctx. Affected: L...

CVE-2026-46019

CVE-2026-46019 concerns the Linux kernel crypto/atmel-aes path. The issue: atmel_aes_buff_init() allocates 4 pages (ATMEL_AES_BUFFER_ORDER) but atmel_aes_buff_cleanup() frees only the first page via free_page(), leaking 3 pages. Resolution: use free_pages() with ATMEL_AES_BUFFER_ORDER to properly...
