CVSS: 5.3EPSS: 0%CPEs: 8EXPL: 0CVE-2024-38618 – ALSA: timer: Set lower bound of start tick time
https://notcve.org/view.php?id=CVE-2024-38618
In the Linux kernel, the following vulnerability has been resolved: ALSA: timer: Set lower bound of start tick time Currently ALSA timer doesn't have the lower limit of the start tick time, and it allows a very small size, e.g. 1 tick with 1ns resolution for hrtimer. Such a situation may lead to an unexpected RCU stall, where the callback repeatedly queuing the expire update, as reported by fuzzer. This patch introduces a sanity check of the timer start tick time, so that the system returns an error when a too small start size is set. As of this patch, the lower limit is hard-coded to 100us, which is small enough but can still work somehow. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ALSA: temporizador: establece el límite inferior del tiempo de inicio. Actualmente, el temporizador ALSA no tiene el límite inferior del tiempo de inicio y permite un tamaño muy pequeño, por ejemplo, 1 tic. con resolución de 1ns para hrtimer. Tal situación puede provocar una parada inesperada de la RCU, donde la devolución de llamada pone en cola repetidamente la actualización caducada, según lo informado por fuzzer. • https://git.kernel.org/stable/c/68396c825c43664b20a3a1ba546844deb2b4e48f https://git.kernel.org/stable/c/74bfb8d90f2601718ae203faf45a196844c01fa1 https://git.kernel.org/stable/c/bdd0aa055b8ec7e24bbc19513f3231958741d0ab https://git.kernel.org/stable/c/83f0ba8592b9e258fd80ac6486510ab1dcd7ad6e https://git.kernel.org/stable/c/ceab795a67dd28dd942d0d8bba648c6c0f7a044b https://git.kernel.org/stable/c/2c95241ac5fc90c929d6c0c023e84bf0d30e84c3 https://git.kernel.org/stable/c/abb1ad69d98cf1ff25bb14fff0e7c3f66239e1cd https://git.kernel.org/stable/c/4a63bd179fa8d3fcc44a0d9d71d941ddd • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •

In the Linux kernel, the following vulnerability has been resolved: wifi: carl9170: re-fix fortified-memset warning The carl9170_tx_release() function sometimes triggers a fortified-memset warning in my randconfig builds: In file included from include/linux/string.h:254, from drivers/net/wireless/ath/carl9170/tx.c:40: In function 'fortify_memset_chk', inlined from 'carl9170_tx_release' at drivers/net/wireless/ath/carl9170/tx.c:283:2, inlined from 'kref_put' at include/linux/kref.h:65:3, inlined from 'carl9170_tx_put_skb' at drivers/net/wireless/ath/carl9170/tx.c:342:9: include/linux/fortify-string.h:493:25: error: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning] 493 | __write_overflow_field(p_size_field, size); Kees previously tried to avoid this by using memset_after(), but it seems this does not fully address the problem. I noticed that the memset_after() here is done on a different part of the union (status) than the original cast was from (rate_driver_data), which may confuse the compiler. Unfortunately, the memset_after() trick does not work on driver_rates[] because that is part of an anonymous struct, and I could not get struct_group() to do this either. Using two separate memset() calls on the two members does address the warning though.

In the Linux kernel, the following vulnerability has been resolved: openrisc: traps: Don't send signals to kernel mode threads OpenRISC exception handling sends signals to user processes on floating point exceptions and trap instructions (for debugging) among others. There is a bug where the trap handling logic may send signals to kernel threads, we should not send these signals to kernel threads, if that happens we treat it as an error. This patch adds conditions to die if the kernel receives these exceptions in kernel mode code. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: openrisc: trampas: no envía señales a subprocesos en modo kernel. El manejo de excepciones de OpenRISC envía señales a los procesos del usuario sobre excepciones de punto flotante e instrucciones de captura (para depuración), entre otros. Hay un error en el que la lógica de manejo de trampas puede enviar señales a los subprocesos del kernel. No debemos enviar estas señales a los subprocesos del kernel; si eso sucede, lo tratamos como un error. • https://git.kernel.org/stable/c/27267655c5313ba0f5a3caa9ad35d887d9a12574 https://git.kernel.org/stable/c/c0ed9a711e3392d73e857faa031d8d349c0d70db https://git.kernel.org/stable/c/075c0405b0d7d9fc490609e988a3af0069596538 https://git.kernel.org/stable/c/cea9d0015c140af39477dd5eeb9b20233a45daa9 https://git.kernel.org/stable/c/c88cfb5cea5f8f9868ef02cc9ce9183a26dcf20f •
