CVE-2026-98061

A flaw was found in the Linux kernel's eBPF Extended Berkeley Packet Filter verifier. A privileged local user with the CAPBPF capability can exploit this vulnerability by loading a crafted program that makes a tail call directly from within a callback function. This triggers an inconsistent...

CVE-2026-74936-gc-potato

CVE-2026-74936 Una reproducción no muy elegante. La línea base requirió algunos ajustes aquí. Mozilla describe este problema como un use-after-free en WebAssembly. El parche público 9823b5c86ffa mantiene vivo el wasm::Code que provoca el trap exacto en JitActivation. La prueba realiza una llamada...

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-2026-89906

CVE-2026-89906 affects the LoongArch BPF JIT in the Linux kernel. The jump offset calculation for tail calls used a stale prior-pass code stride to derive branch distances, which can produce wrong branch offsets and cause soft lockups when extra JIT passes are triggered. The fix recalculates the ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

A out-of-bounds memory read flaw was discovered in the Linux kernel’s BPF subsystem, related to how a user calls the bpftailcall function with a key that is larger than the maxentries of the map. This flaw allows a local user to gain unauthorized access to data...
