CVSS: 5.5EPSS: 0%CPEs: 15EXPL: 0CVE-2024-41035 – USB: core: Fix duplicate endpoint bug by clearing reserved bits in the descriptor
https://notcve.org/view.php?id=CVE-2024-41035
In the Linux kernel, the following vulnerability has been resolved: USB: core: Fix duplicate endpoint bug by clearing reserved bits in the descriptor Syzbot has identified a bug in usbcore (see the Closes: tag below) caused by our assumption that the reserved bits in an endpoint descriptor's bEndpointAddress field will always be 0. As a result of the bug, the endpoint_is_duplicate() routine in config.c (and possibly other routines as well) may believe that two descriptors are for distinct endpoints, even though they have the same direction and endpoint number. This can lead to confusion, including the bug identified by syzbot (two descriptors with matching endpoint numbers and directions, where one was interrupt and the other was bulk). To fix the bug, we will clear the reserved bits in bEndpointAddress when we parse the descriptor. (Note that both the USB-2.0 and USB-3.1 specs say these bits are "Reserved, reset to zero".) This requires us to make a copy of the descriptor earlier in usb_parse_endpoint() and use the copy instead of the original when checking for duplicates. • https://git.kernel.org/stable/c/0a8fd1346254974c3a852338508e4a4cddbb35f1 https://git.kernel.org/stable/c/c3726b442527ab31c7110d0445411f5b5343db01 https://git.kernel.org/stable/c/15668b4354b38b41b316571deed2763d631b2977 https://git.kernel.org/stable/c/8597a9245181656ae2ef341906e5f40af323fbca https://git.kernel.org/stable/c/264024a2676ba7d91fe7b1713b2c32d1b0b508cb https://git.kernel.org/stable/c/b0de742a1be16b76b534d088682f18cf57f012d2 https://git.kernel.org/stable/c/7cc00abef071a8a7d0f4457b7afa2f57f683d83f https://git.kernel.org/stable/c/05b0f2fc3c2f9efda47439557e0d51fac • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •

https://notcve.org/view.php?id=CVE-2024-41034
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix kernel bug on rename operation of broken directory Syzbot reported that in rename directory operation on broken directory on nilfs2, __block_write_begin_int() called to prepare block write may fail BUG_ON check for access exceeding the folio/page size. This is because nilfs_dotdot(), which gets parent directory reference entry ("..") of the directory to be moved or renamed, does not check consistency enough, and may return location exceeding folio/page size for broken directories. Fix this issue by checking required directory entries ("." and "..") in the first chunk of the directory in nilfs_dotdot(). • https://git.kernel.org/stable/c/2ba466d74ed74f073257f86e61519cb8f8f46184 https://git.kernel.org/stable/c/ff9767ba2cb949701e45e6e4287f8af82986b703 https://git.kernel.org/stable/c/24c1c8566a9b6be51f5347be2ea76e25fc82b11e https://git.kernel.org/stable/c/a9a466a69b85059b341239766a10efdd3ee68a4b https://git.kernel.org/stable/c/7000b438dda9d0f41a956fc9bffed92d2eb6be0d https://git.kernel.org/stable/c/1a8879c0771a68d70ee2e5e66eea34207e8c6231 https://git.kernel.org/stable/c/60f61514374e4a0c3b65b08c6024dd7e26150bfd https://git.kernel.org/stable/c/298cd810d7fb687c90a14d8f9fd1b8719 •

In the Linux kernel, the following vulnerability has been resolved: ksmbd: discard write access to the directory open may_open() does not allow a directory to be opened with the write access. However, some writing flags set by client result in adding write access on server, making ksmbd incompatible with FUSE file system.
