CVE-2026-66038

FFmpeg through 8.1.2, fixed in commit 8670835, contains an information disclosure vulnerability in the LCL/ZLIB video decoder that allows attackers to expose uninitialized heap memory by supplying a valid zlib stream that inflates to fewer bytes than the expected frame size. The zlibdecomp functi...

CVE-2026-64253

In the Linux kernel, the following vulnerability has been resolved: kernel/fork: clear PFBLOCKTS in copyprocess PFBLOCKTS is only set in blktimegetns when current-plug is non-NULL, and blkfinishplug clears it via blkflushplug before NULLing the plug pointer. copyprocess breaks the invariant by...
