CVE-2022-49228 relates to the Linux kernel and a bug in BTF decl_tag handling during function tagging in BPF. The issue arises when btf_decl_tag_resolve() checks a function type’s func_proto; the code attempted to access func_proto’s vlen for a type 3 function prototype, which was out of range an...

CVE-2022-49214

CVE-2022-49214 pertains to the Linux kernel on PowerPC 64s where Data SLB (Data Segment) faults do not set DSISR to a useful value, causing misclassification of read vs. write faults. The fix reworks the printing logic to treat SLB faults separately and only print read/write when the fault type c...
