CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-42302 – PCI/DPC: Fix use-after-free on concurrent DPC and hot-removal
https://notcve.org/view.php?id=CVE-2024-42302
In the Linux kernel, the following vulnerability has been resolved: PCI/DPC: Fix use-after-free on concurrent DPC and hot-removal Keith reports a use-after-free when a DPC event occurs concurrently to hot-removal of the same portion of the hierarchy: The dpc_handler() awaits readiness of the secondary bus below the Downstream Port where the DPC event occurred. To do so, it polls the config space of the first child device on the secondary bus. If that child device is concurrently removed, accesses to its struct pci_dev cause the kernel to oops. That's because pci_bridge_wait_for_secondary_bus() neglects to hold a reference on the child device. Before v6.3, the function was only called on resume from system sleep or on runtime resume. Holding a reference wasn't necessary back then because the pciehp IRQ thread could never run concurrently. • https://git.kernel.org/stable/c/d0292124bb5787a2f1ab1316509e801ca89c10fb https://git.kernel.org/stable/c/ffe2318405e605f1b3985ce188eff69e6d1d1baa https://git.kernel.org/stable/c/189f856e76f5463f59efb5fc18dcc1692d04c41a https://git.kernel.org/stable/c/53b54ad074de1896f8b021615f65b27f557ce874 https://git.kernel.org/stable/c/0081032082b5b45ca902b3c3d6986cb5cca69ff2 https://git.kernel.org/stable/c/c52f9e1a9eb40f13993142c331a6cfd334d4b91d https://git.kernel.org/stable/c/2c111413f38ca5cf87557cab89f6d82b0e3433e7 https://git.kernel.org/stable/c/f63df70b439bb8331358a306541893bf4 •

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Update log->page_{mask,bits} if log->page_size changed If an NTFS file system is mounted to another system with different PAGE_SIZE from the original system, log->page_size will change in log_replay(), but log->page_{mask,bits} don't change correspondingly. This will cause a panic because "u32 bytes = log->page_size - page_off" will get a negative value in the later read_log_page(). • https://git.kernel.org/stable/c/b46acd6a6a627d876898e1c84d3f84902264b445 https://git.kernel.org/stable/c/0484adcb5fbcadd9ba0fd4485c42630f72e97da9 https://git.kernel.org/stable/c/b90ceffdc975502bc085ce8e79c6adeff05f9521 https://git.kernel.org/stable/c/2cac0df3324b5e287d8020bc0708f7d2dec88a6f https://git.kernel.org/stable/c/0a4ae2644e2a3b3b219aad9639fb2b0691d08420 https://git.kernel.org/stable/c/2fef55d8f78383c8e6d6d4c014b9597375132696 •
