CVSS: 4.4EPSS: 0%CPEs: 7EXPL: 0CVE-2024-26872 – RDMA/srpt: Do not register event handler until srpt device is fully setup
https://notcve.org/view.php?id=CVE-2024-26872
In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: Do not register event handler until srpt device is fully setup Upon rare occasions, KASAN reports a use-after-free Write in srpt_refresh_port(). This seems to be because an event handler is registered before the srpt device is fully setup and a race condition upon error may leave a partially setup event handler in place. Instead, only register the event handler after srpt device initialization is complete. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: RDMA/srpt: no registrar el controlador de eventos hasta que el dispositivo srpt esté completamente configurado. En raras ocasiones, KASAN informa una escritura de use-after-free en srpt_refresh_port(). Esto parece deberse a que se registra un controlador de eventos antes de que el dispositivo srpt esté completamente configurado y una condición de carrera en caso de error puede dejar en su lugar un controlador de eventos parcialmente configurado. En su lugar, registre el controlador de eventos solo después de que se complete la inicialización del dispositivo srpt. • https://git.kernel.org/stable/c/a42d985bd5b234da8b61347a78dc3057bf7bb94d https://git.kernel.org/stable/c/bdd895e0190c464f54f84579e7535d80276f0fc5 https://git.kernel.org/stable/c/6413e78086caf7bf15639923740da0d91fdfd090 https://git.kernel.org/stable/c/e362d007294955a4fb929e1c8978154a64efdcb6 https://git.kernel.org/stable/c/85570b91e4820a0db9d9432098778cafafa7d217 https://git.kernel.org/stable/c/7104a00fa37ae898a827381f1161fa3286c8b346 https://git.kernel.org/stable/c/ec77fa12da41260c6bf9e060b89234b980c5130f https://git.kernel.org/stable/c/c21a8870c98611e8f892511825c9607f1 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2024-26846
In the Linux kernel, the following vulnerability has been resolved: nvme-fc: do not wait in vain when unloading module The module exit path has race between deleting all controllers and freeing 'left over IDs'. To prevent double free a synchronization between nvme_delete_ctrl and ida_destroy has been added by the initial commit. There is some logic around trying to prevent from hanging forever in wait_for_completion, though it does not handling all cases. E.g. blktests is able to reproduce the situation where the module unload hangs forever. If we completely rely on the cleanup code executed from the nvme_delete_ctrl path, all IDs will be freed eventually. This makes calling ida_destroy unnecessary. We only have to ensure that all nvme_delete_ctrl code has been executed before we leave nvme_fc_exit_module. • https://git.kernel.org/stable/c/4f2c95015ec2a1899161be6c0bdaecedd5a7bfb2 https://git.kernel.org/stable/c/0bf567d6d9ffe09e059bbdfb4d07143cef42c75c https://git.kernel.org/stable/c/085195aa90a924c79e35569bcdad860d764a8e17 https://git.kernel.org/stable/c/baa6b7eb8c66486bd64608adc63fe03b30d3c0b9 https://git.kernel.org/stable/c/c0882c366418bf9c19e1ba7f270fe377a9bf5d67 https://git.kernel.org/stable/c/70fbfc47a392b98e5f8dba70c6efc6839205c982 https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html https://access.redhat.com/security/cve/CVE-2024 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
