https://notcve.org/view.php?id=CVE-2024-53107
In the Linux kernel, the following vulnerability has been resolved: fs/proc/task_mmu: prevent integer overflow in pagemap_scan_get_args() The "arg->vec_len" variable is a u64 that comes from the user at the start of the function. The "arg->vec_len * sizeof(struct page_region))" multiplication can lead to integer wrapping. Use size_mul() to avoid that. Also the size_add/mul() functions work on unsigned long so for 32bit systems we need to ensure that "arg->vec_len" fits in an unsigned long. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: fs/proc/task_mmu: evitar el desbordamiento de enteros en pagemap_scan_get_args() La variable "arg->vec_len" es una u64 que proviene del usuario al inicio de la función. La multiplicación "arg->vec_len * sizeof(struct page_region))" puede provocar un ajuste de enteros. • https://git.kernel.org/stable/c/52526ca7fdb905a768a93f8faa418e9b988fc34b https://git.kernel.org/stable/c/adee03f8903c58a6a559f21388a430211fac8ce9 https://git.kernel.org/stable/c/669b0cb81e4e4e78cff77a5b367c7f70c0c6c05e •

In the Linux kernel, the following vulnerability has been resolved: ima: fix buffer overrun in ima_eventdigest_init_common Function ima_eventdigest_init() calls ima_eventdigest_init_common() with HASH_ALGO__LAST which is then used to access the array hash_digest_size[] leading to buffer overrun. Have a conditional statement to handle this. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ima: se corrige el desbordamiento del búfer en la función ima_eventdigest_init_common La función ima_eventdigest_init() llama a ima_eventdigest_init_common() con HASH_ALGO__LAST, que luego se utiliza para acceder a la matriz hash_digest_size[], lo que provoca un desbordamiento del búfer. Se debe tener una declaración condicional para manejar esto. • https://git.kernel.org/stable/c/9fab303a2cb3d323ca3a32a8b4ab60b451141901 https://git.kernel.org/stable/c/e01aae58e818503f2ffcd34c6f7dc6f90af1057e https://git.kernel.org/stable/c/8a84765c62cc0469864e2faee43aae253ad16082 https://git.kernel.org/stable/c/1ecf0df5205cfb0907eb7984b8671257965a5232 https://git.kernel.org/stable/c/923168a0631bc42fffd55087b337b1b6c54dcff5 •
