CVE-2025-43529

CVE-2025-43529 TL; DR Apple recently shipped iOS 26.2 and iPadOS 26.2, along with a security advisory that includes fixes for WebKit vulnerabilities. One bug in the DFG JIT compiler CVE-2025-43529 stood out, so I decided to dig into it. The JIT compiler correctly recognized that a Phi node where...

CVE-2026-74936-gc-potato

CVE-2026-74936 A not fancy reproduction. The baseline required some fiddling here. Mozilla describes this issue as a WebAssembly use-after-free. Public fix 9823b5c86ffa keeps the exact trapping wasm::Code alive in JitActivation. The test performs a bad-signature cross-instance tail call. A Debugg...

CVE-2026-84118-who-labeled-the-crit-as-a-high

CVE-2026-84118 — SpiderMonkey GC use-after-free Bug 2057457 This is one of those where Mozilla labeled a Critical as a High. So someone might want to go have Firefox update the original bug hunters payment if that's the case. THE TLDR: You can do an OOB R primitive on a controlled pointer and the...

yawkat LZ4 Java: LZ4FrameInputStream reallocates block buffers for every frame, allowing CPU and GC amplification from small inputs

Summary LZ4FrameInputStream allocates two new buffers of the frame's maximum block size, up to 4 MiB each, every time it reads a frame header. Because concatenated frames are read by default, an input made of many minimal empty frames forces about 8 MiB of zeroed heap allocation for every 11 inpu...

CVE-2026-106450 yawkat LZ4 Java: LZ4FrameInputStream reallocates block buffers for every frame, allowing CPU and GC amplification from small inputs

yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.4, net.jpountz.lz4.LZ4FrameInputStream readHeader allocates two new 4 MiB block buffers whenever a maximum-block-size frame header is read, and the default concatenated-frame mode allows attacker-controlled streams containing many...

CVE-2026-106450

Prior to version 1.11.4 , yawkat LZ4 Java is vulnerable to a resource exhaustion issue in the net.jpountz.lz4.LZ4FrameInputStream.readHeader() function. When processing a maximum-block-size frame header in the default concatenated-frame mode, the component allocates two new 4 MiB block buffers. A...
