DEBIAN-CVE-2026-98048
No affected components available
In the Linux kernel, the following vulnerability has been resolved: bpf: don't rewrite bpf_fastcall patterns entered by a jump mark_fastcall_pattern_for_call() must ensure that matched "spill; call; fill" instruction series is not interrupted by a jump. Otherwise the rewrite applied by bpf_remove_fastcall_spills_fills() is not sound. Record the instructions targeted by jumps in insn_aux_data[].jump_target when the CFG is built and use this flag to stop growing a pattern at such an instruction. Jumps to the first spill are fine. Note that existing insn_aux_data[].jmp_point field can't be reused, as it marks subprogram return instructions.
