"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndpaa2-switch: add bounds check for if_id in IRQ handler\n\nThe IRQ handler extracts if_id from the upper 16 bits of the hardware\nstatus register and uses it to index into ethsw->ports[] without\nvalidation. Since if_id can be any 16-bit value (0-65535) but the ports\narray is only allocated with sw_attr.num_ifs elements, this can lead to\nan out-of-bounds read potentially.\n\nAdd a bounds check before accessing the array, consistent with the\nexisting validation in dpaa2_switch_rx()."

"value": "AV:L - The vulnerability is in a hardware IRQ handler for NXP DPAA2 Ethernet switch hardware. The if_id comes from MC firmware via hardware registers, requiring at minimum local access to the system running this hardware. Not remotely triggerable via network packets.\nAC:H - The attacker cannot control the if_id value returned by the MC firmware in the IRQ status register. Triggering an out-of-bounds if_id requires a firmware bug or hardware anomaly, which are conditions beyond the attacker's control.\nPR:L - While the IRQ fires from hardware events, a local user on a system with DPAA2 hardware could potentially trigger link state change events. No special privileges beyond basic local access are required to cause network interface events.\nUI:N - No user interaction is required. The IRQ handler fires automatically in response to hardware events without any user action.\nS:U - The vulnerability affects the kernel in its own security context. There is no crossing of security boundaries such as VM escape or IOMMU bypass.\nC:H - The OOB read on the heap-allocated ports pointer array (up to 64K entries beyond bounds) reads arbitrary kernel heap memory. The dereferenced pointer then accesses further arbitrary memory, potentially disclosing kernel data.\nI:H - The OOB-read pointer is dereferenced and used to call functions that modify port state (link state update, MAC address set, MAC connect/disconnect). If the OOB-read pointer happens to point to attacker-influenced memory, this could enable arbitrary writes.\nA:H - Dereferencing a garbage pointer read from OOB heap memory will almost certainly cause a kernel crash (oops or panic), resulting in complete denial of service."
