CVSS: 5.5EPSS: 0%CPEs: 5EXPL: 0CVE-2024-35827 – io_uring/net: fix overflow check in io_recvmsg_mshot_prep()
https://notcve.org/view.php?id=CVE-2024-35827
In the Linux kernel, the following vulnerability has been resolved: io_uring/net: fix overflow check in io_recvmsg_mshot_prep() The "controllen" variable is type size_t (unsigned long). Casting it to int could lead to an integer underflow. The check_add_overflow() function considers the type of the destination which is type int. If we add two positive values and the result cannot fit in an integer then that's counted as an overflow. However, if we cast "controllen" to an int and it turns negative, then negative values *can* fit into an int type so there is no overflow. Good: 100 + (unsigned long)-4 = 96 <-- overflow Bad: 100 + (int)-4 = 96 <-- no overflow I deleted the cast of the sizeof() as well. That's not a bug but the cast is unnecessary. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: io_uring/net: corregida la comprobación de desbordamiento en io_recvmsg_mshot_prep() La variable "controllen" es de tipo size_t (largo sin firmar). • https://git.kernel.org/stable/c/9b0fc3c054ff2eb13753104884f1045b5bb3a627 https://git.kernel.org/stable/c/868ec868616438df487b9e2baa5a99f8662cc47c https://git.kernel.org/stable/c/59a534690ecc3af72c6ab121aeac1237a4adae66 https://git.kernel.org/stable/c/0c8c74bb59e7d77554016efc34c2d10376985e5e https://git.kernel.org/stable/c/b6563ad0d599110bd5cf8f56c47d279c3ed796fe https://git.kernel.org/stable/c/8ede3db5061bb1fe28e2c9683329aafa89d2b1b4 https://access.redhat.com/security/cve/CVE-2024-35827 https://bugzilla.redhat.com/show_bug.cgi?id=2281183 •

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 •
