CVE-2026-90177

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. This vulnerability arises because the atomic Read-Modify-Write RMW verification process does not consistently check pointer types across all execution paths. Specifically, it only records the instruction pointer type when...

Linux Distros Unpatched Vulnerability : CVE-2026-90177

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - bpf: Check pointer type for all atomic RMW paths Atomic RMW verification records an instruction pointer type only when the current destination is PTRTOARENA. A...

DEBIAN-CVE-2026-90177

In the Linux kernel, the following vulnerability has been resolved: bpf: Check pointer type for all atomic RMW paths Atomic RMW verification records an instruction pointer type only when the current destination is PTRTOARENA. A second path can therefore reach the same instruction with an ordinary...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.10 contains security vulnerabilities. These vulnerabilities stem from the BPF atomic RMW validation, which only records the instruction pointer type when the current target is PTRTOARENA. It does not record the actual target type of all atomic RMW paths. This may allow...
