SUSE CVE-2026-90358

In the Linux kernel, the following vulnerability has been resolved: bpf, x86: Fix trampoline stack size for 128-bit arguments btfdistillfuncproto accepts a function argument up to 16 bytes, so a 128-bit scalar such as int128 reaches the x86 trampoline with argsize == 16. But the current...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from an error in the calculation of the number of registers required for 128-bit parameters by btfdistillfuncproto. As a result, the register storage area is under-sized, and saveargs overwrites adjacent stack slots,...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 5.5. It arises because BPF trampolines retain only 8 bytes of return values, while btfdistillfuncproto expects a 16-byte int128 return value. For target return types such as fexit, fmodret, fsession, and its variants like multi, as well as...
