In the Linux kernel, the following vulnerability has been resolved: s390/bpf: Replace ly instruction with llgf cpunr is a 32 bit value and BPFREG0 is a 64 bit register, when ly loads the cpunr into BPFREG0 it does not zero the upper bits, but llgf does...
CVE-2026-93147
CVE-2026-93147 affects the Linux kernel on the s390 architecture within the BPF (Berkeley Packet Filter) subsystem. The root cause is that the ly instruction loads the 32-bit value cpu_nr into the 64-bit register BPF_REG_0 without zeroing the upper 32 bits, leaving stale data that can corrupt sub...
CVE-2026-90211
CVE-2026-90211 affects the Linux kernel on the s390x architecture. The vulnerability resides in the BPF JIT compiler's handling of read-modify-write (RMW) atomics on arena pointers. Specifically, bpf_jit_probe_atomic_pre() leaves probe->reg at -1 (the sentinel from bpf_jit_probe_init()), so wh...
CVE-2026-90211 bpf, s390: Clear fetch destination on faulting arena atomic
In the Linux kernel, the following vulnerability has been resolved: bpf, s390: Clear fetch destination on faulting arena atomic Same missing register clear as on riscv64. A RMW atomic on an arena pointer is converted to BPFPROBEATOMIC and gets an exception table entry, but bpfjitprobeatomicpre on...

PT-2026-94943
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the s390/bpf component where the ly instruction is used to load the 32-bit cpu nr value into the 64-bit BPF REG 0 register. This process fails to zero the upper bits o...
