In the Linux kernel, the following vulnerability has been resolved: netfs: Fix netfs_invalidate_folio() to clear dirty bit if all changes gone If a… (CVE-2026-64064)CVE-2026-64064 0 A vulnerability in the Linux kernel's netfs subsystem was resolved by fixing netfs_invalidate_folio() to clear the dirty bit when all changes to a folio are removed. Without this fix, truncating a file after a streaming write could leave a folio marked dirty without the associated netfs_folio struct, causing a kernel oops when the folio is read via mmap(). This issue could be reproduced under specific conditions involving streaming writes, truncation, and memory mapping. The fix involves calling folio_cancel_dirty() to clear the dirty flag appropriately. Join the discussion | GCVE Database | 07/19/2026, 18:31:51 UTC Added: 07/19/2026, 19:38:17 UTC |
