octeontx2-af: fix out-of-bounds read setting MSI-X irq affinity<\/p>\n
rvu_register_interrupts() walks every MSI-X vector and uses strstr()
\nto match “Mbox” or “FLR” in irq_name before pinning those interrupts
\nto CPU 0. irq_name is a per-vector NAME_SIZE buffer, but not every
\nslot is populated before this loop runs. strstr() keeps scanning until
\nit finds a NUL terminator, so an uninitialized slot can trigger a KASAN
\nslab-out-of-bounds read at boot when debug options are enabled.<\/p>\n
Use strnstr() with NAME_SIZE to bound the search within each vector’s
\nname buffer.<\/p>\n","protected":false},"excerpt":{"rendered":"
