CVE-2026-64391

The CVE-2026-64391 issue affects the Linux kernel ksmbd component, where alternate data streams (ADS) stored as xattrs were read/written using current task credentials via VFS xattr paths. The root cause is that ADS I/O did not use the credentials captured when the SMB handle was opened, allowing...

CVE-2026-64391 ksmbd: use opener credentials for ADS I/O

In the Linux kernel, the following vulnerability has been resolved: ksmbd: use opener credentials for ADS I/O Alternate data streams are stored as xattrs. Unlike regular file I/O, their read and write paths therefore call VFS xattr helpers which recheck inode permissions and LSM policy using the...

Kimi K3 Agents Found Redis Zero-Days and Built RCE Exploit, Researchers Say

Redis shipped seven security releases on July 23 after researchers published authenticated RCE PoCs for stock Redis 6.2.22, 7.4.9, 8.6.4, and 8.8.0. All four chains require RESTORE. The Streams chains also need EVAL and XGROUP; the 8.8.0 chain needs EVAL and the bundled RedisBloom module. Redis...

CVE-2026-6924

CVE-2026-6924 describes a weak entropy initialization in SiWx917 TinyCrypt used by Silicon Labs Matter, causing the DRBG to seed from a predictable source. As a result, all random numbers in the Matter code may derive from the same stream, reducing unpredictability. The CVSS vector in the documen...

CVE-2026-25800

Quinn-quic: The Assembler handling unordered stream fragments can cause high memory overhead and potential memory exhaustion for non-contiguous fragments when reading RecvStream via AsyncRead, in versions 0.1.0 through 0.11.14. The issue arises from overhead in defragmentation of fragments with g...

pypdf: Possible infinite loop for not terminated inline images

Impact An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires parsing the content stream of a page with a not terminated inline image, as done when extracting the page text for example. Patches This has been fixed in pypdf==6.14.1. Workarounds If yo...

pypdf: Possible long runtimes for repeated malformed cross-reference entries

Impact An attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires cross-reference streams with repeated malformed cross-reference streams. Patches This has been fixed in pypdf==6.14.0. Workarounds If you cannot upgrade yet, consider applying the changes fr...

Name of the Vulnerable Software and Affected Versions Silicon Labs Matter SiWx917 affected versions not specified Description A bug in the entropy initialization for SiWx917 causes the Deterministic Random Bit Generator DRBG, a mechanism used to produce random numbers, to use a predictable seed...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop through the rtpasffixheader function in libavformat/rtpdecasf.c. An attacker can exhaust CPU and prevent normal service by sending a crafted RTP/ASF stream containing ASF objects with a chunksize smaller than the 24-byte...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in adxdecodeframe in libavcodec/adxdec.c. An attacker can trigger memory corruption or a crash by supplying a crafted ADX or AAX audio stream that delivers AVPKTDATANEWEXTRADATA mid-stream and changes the channel...

CVE-2026-64834

FFmpeg versions 0.6.3 through 8.1.2 contain an infinite loop vulnerability in the RTP/ASF demuxer within libavformat/rtpdecasf.c that allows remote attackers to cause denial of service by sending a crafted RTP/ASF stream. The rtpasffixheader function fails to validate a minimum chunksize when...

SUSE CVE-2026-56816

Netty is a network application framework for development of protocol servers and clients. Prior to 4.2.16.Final, Netty's Http3FrameCodec buffers incoming data for HTTP/3 reserved frame types up to the wire-specified payload length without limits; decodeFrame trusts payLoadLength, allowing an...
