in response to Hacker News... I see you jokers on the orange websitehn are giving me a hard time. I will make a few choice responses below, but first I offer a challenge: I will send $500 of my own money to the first person who can demonstrate this attack without ifunc. I am genuinely interested,...

CVE-2026-98214

A flaw was found in the Linux kernel. A local user can bypass Security-Enhanced Linux SELinux access controls to execute restricted files on stacked filesystems. When modifying memory protections using the mprotect system call, the kernel fails to recheck security permissions on intermediate laye...

CVE-2026-98215

In the Linux kernel, the following vulnerability has been resolved: selinux: preserve user SID across nested backing files SELinux saves the user file SID in a backing-file security blob so it remains available after mmap replaces vma-vmfile with a backing file. For nested backing files overlayfs...

CVE-2026-98215

The Linux kernel contains a vulnerability in SELinux related to how user file SIDs are preserved across nested backing files, such as overlayfs over overlayfs or FUSE passthrough . When mmap() replaces vma->vm_file with a backing file, the system may incorrectly use the SID of the mounter inst...
