"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndm mirror log: round up region bitmap size to BITS_PER_LONG\n\nThe code in dm-log rounds up bitset_size to 32 bits. It then uses\nfind_next_zero_bit_le on the allocated region. find_next_zero_bit_le\naccesses the bitmap using unsigned long pointers. So, on 64-bit\narchitectures, it may access 4 bytes beyond the allocated size.\n\nFix this bug by rounding up bitset_size to BITS_PER_LONG.\n\nThis bug was found by running the lvm2 testsuite with kasan."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dm mirror log: redondear el tama\u00f1o del mapa de bits de la regi\u00f3n a BITS_PER_LONG El c\u00f3digo en dm-log redondea bitset_size a 32 bits. Luego usa find_next_zero_bit_le en la regi\u00f3n asignada. find_next_zero_bit_le accede al mapa de bits usando punteros largos sin signo. Por lo tanto, en arquitecturas de 64 bits, puede acceder a 4 bytes m\u00e1s all\u00e1 del tama\u00f1o asignado. Corrija este error redondeando bitset_size a BITS_PER_LONG. Este error se encontr\u00f3 ejecutando el conjunto de pruebas lvm2 con kasan."
