DEBIAN-CVE-2026-98061

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject tail calls directly from callback frames A tail call from a non-zero frame is modeled as a return from that frame. The verifier makes R0 unknown and calls preparefuncexit for the taken branch. When the current frame i...

CVE-2026-98061

The Linux kernel contains a vulnerability in the BPF verifier where tail calls made directly from synchronous callback frames trigger a verifier bug. The root cause is that prepare_func_exit() marks register R0 as precise for callbacks, but the tail-call path synthesizes R0 instead of deriving it...

CVE-2026-89926

CVE-2026-89926 affects the Linux kernel KVM s390 subsystem in the __import_wp_info() function. The root cause is a type truncation : the user-space-controlled kvm_hw_breakpoint::len (a __u64) is assigned to wp_info->len (an int). The bounds check evaluates the truncated value, but the subseque...
