CVSS: -EPSS: 0%CPEs: 6EXPL: 0CVE-2021-47617 – PCI: pciehp: Fix infinite loop in IRQ handler upon power fault
https://notcve.org/view.php?id=CVE-2021-47617
In the Linux kernel, the following vulnerability has been resolved: PCI: pciehp: Fix infinite loop in IRQ handler upon power fault The Power Fault Detected bit in the Slot Status register differs from all other hotplug events in that it is sticky: It can only be cleared after turning off slot power. Per PCIe r5.0, sec. 6.7.1.8: If a power controller detects a main power fault on the hot-plug slot, it must automatically set its internal main power fault latch [...]. The main power fault latch is cleared when software turns off power to the hot-plug slot. The stickiness used to cause interrupt storms and infinite loops which were fixed in 2009 by commits 5651c48cfafe ("PCI pciehp: fix power fault interrupt storm problem") and 99f0169c17f3 ("PCI: pciehp: enable software notification on empty slots"). Unfortunately in 2020 the infinite loop issue was inadvertently reintroduced by commit 8edf5332c393 ("PCI: pciehp: Fix MSI interrupt race"): The hardirq handler pciehp_isr() clears the PFD bit until pciehp's power_fault_detected flag is set. That happens in the IRQ thread pciehp_ist(), which never learns of the event because the hardirq handler is stuck in an infinite loop. Fix by setting the power_fault_detected flag already in the hardirq handler. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: PCI: pciehp: soluciona el bucle infinito en el controlador IRQ ante un fallo de alimentación. • https://git.kernel.org/stable/c/a8cc52270f3d8e8f4faf01ffd6c4a95bbfb55ba4 https://git.kernel.org/stable/c/4667358dab9cc07da044d5bc087065545b1000df https://git.kernel.org/stable/c/8edf5332c39340b9583cf9cba659eb7ec71f75b5 https://git.kernel.org/stable/c/ff27f7d0333cff89ec85c419f431aca1b38fb16a https://git.kernel.org/stable/c/464da38ba827f670deac6500a1de9a4f0f44c41d https://git.kernel.org/stable/c/3b4c966fb156ff3e70b2526d964952ff7c1574d9 https://git.kernel.org/stable/c/1db58c6584a72102e98af2e600ea184ddaf2b8af https://git.kernel.org/stable/c/6d6f1f0dac3e3441ecdb1103d4efb11b9 •

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: HCI: Remove HCI_AMP support Since BT_HS has been remove HCI_AMP controllers no longer has any use so remove it along with the capability of creating AMP controllers. Since we no longer need to differentiate between AMP and Primary controllers, as only HCI_PRIMARY is left, this also remove hdev->dev_type altogether. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Bluetooth: HCI: eliminar la compatibilidad con HCI_AMP Dado que se eliminó BT_HS, los controladores HCI_AMP ya no tienen ningún uso, así que elimínelos junto con la capacidad de crear controladores AMP. Como ya no necesitamos diferenciar entre los controladores AMP y primarios, ya que solo queda HCI_PRIMARY, esto también elimina hdev->dev_type por completo. • https://git.kernel.org/stable/c/244bc377591c3882f454882357bc730c90cbedb5 https://git.kernel.org/stable/c/5af2e235b0d5b797e9531a00c50058319130e156 https://git.kernel.org/stable/c/d3c7b012d912b31ad23b9349c0e499d6dddd48ec https://git.kernel.org/stable/c/af1d425b6dc67cd67809f835dd7afb6be4d43e03 https://git.kernel.org/stable/c/84a4bb6548a29326564f0e659fb8064503ecc1c7 •

In the Linux kernel, the following vulnerability has been resolved: usb-storage: alauda: Check whether the media is initialized The member "uzonesize" of struct alauda_info will remain 0 if alauda_init_media() fails, potentially causing divide errors in alauda_read_data() and alauda_write_lba(). - Add a member "media_initialized" to struct alauda_info. - Change a condition in alauda_check_media() to ensure the first initialization. - Add an error check for the return value of alauda_init_media(). En el kernel de Linux, se resolvió la siguiente vulnerabilidad: usb-storage: alauda: compruebe si el medio está inicializado. El miembro "uzonesize" de la estructura alauda_info permanecerá 0 si alauda_init_media() falla, lo que podría provocar errores de división en alauda_read_data() y alauda_write_lba(). - Agregue un miembro "media_initialized" a la estructura alauda_info. - Cambiar una condición en alauda_check_media() para asegurar la primera inicialización. - Agregue una verificación de errores para el valor de retorno de alauda_init_media(). • https://git.kernel.org/stable/c/e80b0fade09ef1ee67b0898d480d4c588f124d5f https://git.kernel.org/stable/c/e0aab7b07a9375337847c9d74a5ec044071e01c8 https://git.kernel.org/stable/c/51fe16c058acb22f847e69bc598066ed0bcd5c15 https://git.kernel.org/stable/c/f68820f1256b21466ff094dd97f243b7e708f9c1 https://git.kernel.org/stable/c/3eee13ab67f65606faa66e0c3c729e4f514838fd https://git.kernel.org/stable/c/e0e2eec76920a133dd49a4fbe4656d83596a1361 https://git.kernel.org/stable/c/2cc32639ec347e3365075b130f9953ef16cb13f1 https://git.kernel.org/stable/c/24bff7f714bdff97c2a75a0ff6a368cdf • CWE-457: Use of Uninitialized Variable •
CVSS: -EPSS: 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 •

https://notcve.org/view.php?id=CVE-2024-38616
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.
