Title
netfs: Fix overrun check in netfs_extract_user_iter()
Summary
In the Linux kernel, the following vulnerability has been resolved: netfs: Fix overrun check in netfs_extract_user_iter() Fix netfs_extract_user_iter() so that if iov_iter_extract_pages() overfills pages[], then those pages don't get included in the iterator constructed at the end of the function. If there was an overfill, memory corruption has already happened.
Severity

Remote peers cannot directly control the local user iterator that triggers extraction.\nAC:L - The attacker controls and can repeatedly submit the UBUF or IOVEC layout, and corruption occurs synchronously once the overfill condition is reached. No race, timing window, or victim-controlled state is required.\nPR:L - An ordinary unprivileged process with permission to access a file on an existing affected mount can reach the helper. No capability or administrative privilege is checked on the I/O path.\nUI:N - The attacker directly opens and performs I/O on the accessible file without requiring another user to act. An existing affected mount is a deployment prerequisite, not per-attack victim interaction.\nS:U - The corruption compromises the same host kernel that processes the local I/O. It does not inherently cross a VM, IOMMU, or other distinct security authority.\nC:H - The overfill writes page pointers beyond the allocated kernel buffer and the malformed bvec can subsequently access unpopulated descriptors. Exploitation of this kernel heap corruption can expose arbitrary kernel memory.\nI:H - The bug produces an out-of-bounds kernel heap write and can cause adjacent memory to be interpreted as bvec descriptors. Heap grooming could turn this into arbitrary memory modification or control-flow hijacking.\nA:H - The corruption can cause a kernel oops, panic, or hang, while aborted extraction can also leak pinned pages. An attacker can repeat the triggering I/O to sustain denial of service."

Taxonomy of the tags.




Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Sightings

Author Source Type Date Other

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
