kernel: net: bridge: stop fast-leave after deleting a port group

A flaw was found in the Linux kernel's network bridge module. When handling multicast fast-leave, a vulnerability exists where the system may attempt to access a port group after it has been deleted. This can occur if multicast-to-unicast was previously enabled and then disabled, leading to a sta...

CVE-2026-87962

t-digest versions 3.1 through 3.3 (a Java library for approximate quantile estimation maintained by tdunning on GitHub) contain a denial of service vulnerability in MergingDigest.fromBytes . The root cause is a failure to validate length and capacity fields read from serialized data; a crafted se...

CVE-2026-87961 ESP32-audioI2S 3.4.4 through 4.0.0 Heap-based Out-of-Bounds Read via Shadowed Length Parameter in read_ID3_Header

ESP32-audioI2S versions 3.4.4 through 4.0.0 contain a heap-based out-of-bounds read vulnerability in the readID3Header function due to a shadowed length parameter in ID3 synchronized-lyrics processing. Attackers can craft malicious MP3 files or HTTP audio streams with oversized frame size...

CVE-2026-59985

A flaw was found in OpenEXR. A remote attacker could provide a specially crafted RLE-compressed EXR image, which causes a 64-bit unpacked size to truncate before memory allocation. This leads to a heap out-of-bounds read when unpack32bit attempts to read beyond the allocated buffer. Successful...

CVE-2026-87823

A flaw was found in zstd-jni. This vulnerability arises from insufficient bounds checks in direct-ByteBuffer frame-size native methods, which allows attackers to provide negative or overflowing offsets. A remote attacker can exploit this by supplying specially crafted negative offset values,...

FFmpeg: Denial of Service via crafted RTP/ASF stream

A flaw was found in FFmpeg. A remote attacker can exploit an infinite loop vulnerability in the RTP/ASF demuxer by sending a specially crafted stream. This vulnerability occurs because the rtpasffixheader function does not properly validate the size of data chunks, preventing the processing loop...

ffmpeg: FFmpeg: Arbitrary code execution via crafted video in vf_hqdn3d filter

A flaw was found in FFmpeg. A remote attacker can exploit a heap out-of-bounds write vulnerability within the vfhqdn3d filter by providing a specially crafted video file. When filtergraph reinitialization is disabled, the filter allocates undersized memory buffers for video frames. Subsequent...

Open WebUI: Any authenticated user can hang the server via message deletion in a cyclic chat tree

SummaryChat histories are stored as an unvalidated JSON object. After a message is deleted, the code that picks the chat's new current message walked down the childrenIds links without recording where it had already been. Any account with the default user role could store a chat whose messages li...

PYSEC-2026-3879 Open WebUI: Any authenticated user can hang the server via a cyclic chat message history

Summary Chat histories are stored as an unvalidated JSON object. The walk that reconstructs a chat's message chain detected repeats using each message's own id field while moving through the history by map key, so a message that simply omitted id was never recorded as visited. A history whose...

PYSEC-2026-3846 HTTPX2: Streaming response decompression does not bound peak memory (decompression amplification)

Summary When decoding a compressed response body gzip, deflate, br, or zstd, HTTPX2 fully decompressed each network read before yielding content to the application. A small compressed input could therefore cause a large intermediate memory allocation, even when the application streamed the respon...

vLLM: ReDoS via structured_outputs.regex in the lm-format-enforcer backend (no compile timeout) — missed sibling of GHSA-rwxx-mrjm-wc2m

SummaryThe fix for GHSA-rwxx-mrjm-wc2m "ReDoS via structuredoutputs.regex compiled without timeout" wrapped the regex compile in the xgrammar and outlines backends with compileregexwithtimeout and, for outlines, validateregexisbuildable. The lm-format-enforcer backend was left unguarded: it...

vLLM: Derender endpoints decode caller-supplied GenerateResponse token IDs without output bounds

SummaryThe /v1/completions/derender and /v1/chat/completions/derender endpoints accept caller-supplied GenerateResponse objects and postprocess every nested choices.tokenids list directly. Unlike the normal render/generate path, derender does not enforce model context length, resolved maxtokens,...
