In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: fix integer overflow in bpf_msg_pop_data() bounds check start and… (CVE-2026-74256)CVE-2026-74256 0 A vulnerability in the Linux kernel's BPF sockmap implementation was fixed to address an integer overflow in the bpf_msg_pop_data() function's bounds check. The issue involved 32-bit addition of start and len values that could wrap around, bypassing bounds checks and causing out-of-bounds memory access leading to kernel crashes. The fix casts the addition to 64-bit to prevent overflow and changes a variable type to avoid sign confusion.
