Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: iouring/kbuf: Reallocate the buf lists upon upgrade. The function IORINGREGISTERPBUFRING can reuse an old struct iobufferlist if it was created for a legacy selected buffer and has been emptied. This violates the requirement that...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Wifi: ath12k: Fixed an invalid entry fetch in ath12kdpmonsrngprocess. Currently, ath12kdpmonsrngprocess uses ath12khalsrngsrcgetnextentry to fetch the next entry from the destination ring. This is incorrect because...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: bnxten: Fixed the receive ring space parameters when XDP is active. The MTU setting at the time a XDP multi-buffer is attached determines whether the aggregation ring will be used and the rxskbfunc handler. This is done in...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Ring-Buffer: Do not trigger WARNON due to a commitoverrun. When reading a memory-mapped buffer, the reader page is simply swapped out with the last page written to the write buffer. If the reader page is the same as the commit...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: USB: xHCI – Fix for isochronous Ring Underrun/Overrun event handling The TRB pointer associated with these events points to the enqueue location when an error occurs in xHCI 1.1+ HCs; for older versions, this pointer is NULL. By...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Ring-buffer: Validates the persistent meta-data subbuf array. The meta-data for a mapped ring buffer contains an array of indexes to all the subbuffers. The first entry represents the “reader page,” and the remaining entries...

PT-2025-29533 · Crates.Io · Slice-Ring-Buffer

The crate slice-ring-buffer was developed as a fork of slice-deque to continue maintenance and provide security patches, since the latter has been officially unmaintained RUSTSEC-2020-0158. While slice-ring-buffer has addressed some previously reported memory safety issues inherited from its fork...

A Crack in the Bark: Leveraging Public Knowledge to Remove Tree-Ring Watermarks

We present a novel attack specifically designed against Tree-Ring, a watermarking technique for diffusion models known for its high imperceptibility and robustness against removal attacks. Unlike previous removal attacks, which rely on strong assumptions about attacker capabilities, our attack on...
