In the Linux kernel, the following vulnerability has been resolved: wifi: libertas: fix some memleaks in lbs_allocate_cmd_buffer() In the for statement of lbs_allocate_cmd_buffer(), if the allocation of cmdarray[i].cmdbuf fails, both cmdarray and cmdarray[i].cmdbuf needs to be freed. Otherwise, there will be memleaks in lbs_allocate_cmd_buffer(). En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: wifi: libertas: arreglados algunas memleaks en lbs_allocate_cmd_buffer() En la declaración for de lbs_allocate_cmd_buffer(), si falló la asignación de cmdarray[i].cmdbuf, tanto cmdarray como cmdarray[i] Es necesario liberar ].cmdbuf.

CVSS: -EPSS: 0%CPEs: 10EXPL: 0CVE-2024-35825 – usb: gadget: ncm: Fix handling of zero block length packets
https://notcve.org/view.php?id=CVE-2024-35825
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ncm: Fix handling of zero block length packets While connecting to a Linux host with CDC_NCM_NTB_DEF_SIZE_TX set to 65536, it has been observed that we receive short packets, which come at interval of 5-10 seconds sometimes and have block length zero but still contain 1-2 valid datagrams present. According to the NCM spec: "If wBlockLength = 0x0000, the block is terminated by a short packet. In this case, the USB transfer must still be shorter than dwNtbInMaxSize or dwNtbOutMaxSize. If exactly dwNtbInMaxSize or dwNtbOutMaxSize bytes are sent, and the size is a multiple of wMaxPacketSize for the given pipe, then no ZLP shall be sent. wBlockLength= 0x0000 must be used with extreme care, because of the possibility that the host and device may get out of sync, and because of test issues. wBlockLength = 0x0000 allows the sender to reduce latency by starting to send a very large NTB, and then shortening it when the sender discovers that there’s not sufficient data to justify sending a large NTB" However, there is a potential issue with the current implementation, as it checks for the occurrence of multiple NTBs in a single giveback by verifying if the leftover bytes to be processed is zero or not. If the block length reads zero, we would process the same NTB infintely because the leftover bytes is never zero and it leads to a crash. Fix this by bailing out if block length reads zero. • https://git.kernel.org/stable/c/ff3ba016263ee93a1c6209bf5ab1599de7ab1512 https://git.kernel.org/stable/c/e7ca00f35d8a17af1ae19d529193ebc21bfda164 https://git.kernel.org/stable/c/17c653d4913bbc50d284aa96cf12bfc63e41ee5c https://git.kernel.org/stable/c/7014807fb7efa169a47a7a0a0a41d2c513925de0 https://git.kernel.org/stable/c/49fbc18378ae72a47feabee97fdb86f3cea09765 https://git.kernel.org/stable/c/427694cfaafa565a3db5c5ea71df6bc095dca92f https://git.kernel.org/stable/c/5bdf93a2f5459f944b416b188178ca4a92fd206f https://git.kernel.org/stable/c/4bf1a9d20c65b9e80ca4b171267103f8d •

In the Linux kernel, the following vulnerability has been resolved: vt: fix unicode buffer corruption when deleting characters This is the same issue that was fixed for the VGA text buffer in commit 39cdb68c64d8 ("vt: fix memory overlapping when deleting chars in the buffer"). The cure is also the same i.e. replace memcpy() with memmove() due to the overlaping buffers. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: vt: corregida la corrupción del búfer Unicode al eliminar caracteres. Este es el mismo problema que se solucionó para el búfer de texto VGA en la confirmación 39cdb68c64d8 ("vt: corrige la superposición de memoria al eliminar caracteres en el búfer "). La solución también es la misma, es decir, reemplazar memcpy() con memmove() debido a la superposición de buffers. • https://git.kernel.org/stable/c/81732c3b2fede049a692e58a7ceabb6d18ffb18c https://git.kernel.org/stable/c/fc7dfe3d123f00e720be80b920da287810a1f37d https://git.kernel.org/stable/c/ff7342090c1e8c5a37015c89822a68b275b46f8a https://git.kernel.org/stable/c/1ce408f75ccf1e25b3fddef75cca878b55f2ac90 https://git.kernel.org/stable/c/0190d19d7651c08abc187dac3819c61b726e7e3f https://git.kernel.org/stable/c/994a1e583c0c206c8ca7d03334a65b79f4d8bc51 https://git.kernel.org/stable/c/7529cbd8b5f6697b369803fe1533612c039cabda https://git.kernel.org/stable/c/2933b1e4757a0a5c689cf48d80b1a2a85 •

In the Linux kernel, the following vulnerability has been resolved: usb: udc: remove warning when queue disabled ep It is possible trigger below warning message from mass storage function, WARNING: CPU: 6 PID: 3839 at drivers/usb/gadget/udc/core.c:294 usb_ep_queue+0x7c/0x104 pc : usb_ep_queue+0x7c/0x104 lr : fsg_main_thread+0x494/0x1b3c Root cause is mass storage function try to queue request from main thread, but other thread may already disable ep when function disable. As there is no function failure in the driver, in order to avoid effort to fix warning, change WARN_ON_ONCE() in usb_ep_queue() to pr_debug(). En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: udc: elimina la advertencia cuando la cola está deshabilitada ep Es posible que se active el siguiente mensaje de advertencia desde la función de almacenamiento masivo, ADVERTENCIA: CPU: 6 PID: 3839 en drivers/usb/gadget/udc /core.c:294 usb_ep_queue+0x7c/0x104 pc: usb_ep_queue+0x7c/0x104 lr: fsg_main_thread+0x494/0x1b3c La causa principal es que la función de almacenamiento masivo intenta poner en cola la solicitud desde el hilo principal, pero es posible que otro hilo ya deshabilite ep cuando la función se deshabilita. Como no hay ningún fallo de función en el controlador, para evitar el esfuerzo de corregir la advertencia, cambie WARN_ON_ONCE() en usb_ep_queue() a pr_debug(). • https://git.kernel.org/stable/c/2b002c308e184feeaeb72987bca3f1b11e5f70b8 https://git.kernel.org/stable/c/68d951880d0c52c7f13dcefb5501b69b8605ce8c https://git.kernel.org/stable/c/3e944ddc17c042945d983e006df7860687a8849a https://git.kernel.org/stable/c/df5cbb908f1687e8ab97e222a16b7890d5501acf https://git.kernel.org/stable/c/f74c5e0b54b02706d9a862ac6cddade30ac86bcf https://git.kernel.org/stable/c/99731076722eb7ed26b0c87c879da7bb71d24290 https://git.kernel.org/stable/c/36177c2595df12225b95ce74eb1ac77b43d5a58c https://git.kernel.org/stable/c/30511676eb54d480d014352bf784f0257 •
