Title
netlabel: fix out-of-bounds memory accesses
Summary
In the Linux kernel, the following vulnerability has been resolved: netlabel: fix out-of-bounds memory accesses There are two array out-of-bounds memory accesses, one in cipso_v4_map_lvl_valid(), the other in netlbl_bitmap_walk(). Both errors are embarassingly simple, and the fixes are straightforward. As a FYI for anyone backporting this patch to kernels prior to v4.8, you'll want to apply the netlbl_bitmap_walk() patch to cipso_v4_bitmap_walk() as netlbl_bitmap_walk() doesn't exist before Linux v4.8.

Both\nerrors are embarassingly simple, and the fixes are straightforward.\n\nAs a FYI for anyone backporting this patch to kernels prior to v4.8,\nyou\u0027ll want to apply the netlbl_bitmap_walk() patch to\ncipso_v4_bitmap_walk() as netlbl_bitmap_walk() doesn\u0027t exist before\nLinux v4.8."

This is a net/ stack path processing remote peer packet data.\nAC:L - With a CIPSO MAP_TRANS DOI configured (the labeled-networking deployment this subsystem targets), an attacker reliably triggers the OOB by setting an out-of-range level byte or category bitmap; DOI values are probeable via ICMP parameter-problem offsets. No race or other attacker-uncontrollable condition is required.\nPR:N - Incoming skbs take the CIPSO path in __ip_options_compile without CAP_NET_RAW or any authentication; the privilege check applies only when skb is NULL (setsockopt). A remote unauthenticated sender can trigger the vulnerable validation.\nUI:N - Exploitation requires only sending crafted IP packets to the host; no victim user action is needed.\nS:U - Impact is confined to the receiving kernel\u0027s NetLabel/CIPSO processing and memory; there is no VM escape, IOMMU bypass, or other cross-authority boundary crossing.\nC:H - cipso_v4_map_lvl_valid indexes an attacker-controlled u8 into the DOI level array without a size check, enabling a large kernel heap OOB read (up to ~1KB when cipso_size is small). Per guidance, unbounded OOB reads score Confidentiality High.\nI:N - Both defects are out-of-bounds reads with no write, UAF, or control-flow corruption primitive; later map_lvl_ntoh still bounds-checks before applying labels, so there is no integrity impact.\nA:H - The OOB reads can fault on unmapped pages and cause a kernel oops/panic, and a remote attacker can trigger them repeatedly for DoS against CIPSO-enabled hosts."

This is a net/ stack path processing remote peer packet data.\nAC:L - With a CIPSO MAP_TRANS DOI configured (the labeled-networking deployment this subsystem targets), an attacker reliably triggers the OOB by setting an out-of-range level byte or category bitmap; DOI values are probeable via ICMP parameter-problem offsets. No race or other attacker-uncontrollable condition is required.\nPR:N - Incoming skbs take the CIPSO path in __ip_options_compile without CAP_NET_RAW or any authentication; the privilege check applies only when skb is NULL (setsockopt). A remote unauthenticated sender can trigger the vulnerable validation.\nUI:N - Exploitation requires only sending crafted IP packets to the host; no victim user action is needed.\nS:U - Impact is confined to the receiving kernel\u0027s NetLabel/CIPSO processing and memory; there is no VM escape, IOMMU bypass, or other cross-authority boundary crossing.\nC:H - cipso_v4_map_lvl_valid indexes an attacker-controlled u8 into the DOI level array without a size check, enabling a large kernel heap OOB read (up to ~1KB when cipso_size is small). Per guidance, unbounded OOB reads score Confidentiality High.\nI:N - Both defects are out-of-bounds reads with no write, UAF, or control-flow corruption primitive; later map_lvl_ntoh still bounds-checks before applying labels, so there is no integrity impact.\nA:H - The OOB reads can fault on unmapped pages and cause a kernel oops/panic, and a remote attacker can trigger them repeatedly for DoS against CIPSO-enabled hosts."
