CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2023-52664 – net: atlantic: eliminate double free in error handling logic
https://notcve.org/view.php?id=CVE-2023-52664
In the Linux kernel, the following vulnerability has been resolved: net: atlantic: eliminate double free in error handling logic Driver has a logic leak in ring data allocation/free, where aq_ring_free could be called multiple times on same ring, if system is under stress and got memory allocation error. Ring pointer was used as an indicator of failure, but this is not correct since only ring data is allocated/deallocated. Ring itself is an array member. Changing ring allocation functions to return error code directly. This simplifies error handling and eliminates aq_ring_free on higher layer. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net: atlantic: elimina double free en la lógica de manejo de errores El controlador tiene una fuga lógica en la asignación de datos del anillo/free, donde se podría llamar a aq_ring_free varias veces en el mismo anillo, si el sistema está bajo estrés y obtuve un error de asignación de memoria. Se utilizó un puntero de anillo como indicador de error, pero esto no es correcto ya que solo se asignan/desasignan datos de anillo. El anillo en sí es un miembro de la matriz. Cambiar las funciones de asignación de anillos para devolver el código de error directamente. • https://git.kernel.org/stable/c/0edb3ae8bfa31cd544b0c195bdec00e036002b5d https://git.kernel.org/stable/c/c11a870a73a3bc4cc7df6dd877a45b181795fcbf https://git.kernel.org/stable/c/d1fde4a7e1dcc4d49cce285107a7a43c3030878d https://git.kernel.org/stable/c/b3cb7a830a24527877b0bc900b9bd74a96aea928 •

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 •
