[CVE-2025-37752] Two Bytes Of Madness: Pwning The Linux Kernel With A 0x0000 Written 262636 Bytes Out-Of-Bounds

Great article by D3vil about exploiting a type confusion in the network scheduler subsystem and pwning all kernelCTF instances.

Author exploited a severely-limited OOB side-effect of the bug to corrupt pipe_inode_info->tmp_page and gain a page UAF read/write primitive. Researcher then swapped the private_data and f_cred fields of a signalfd file structure and overwrote the credentials via signalfd_ctx.
