https://notcve.org/view.php?id=CVE-2023-52655
In the Linux kernel, the following vulnerability has been resolved: usb: aqc111: check packet for fixup for true limit If a device sends a packet that is inbetween 0 and sizeof(u64) the value passed to skb_trim() as length will wrap around ending up as some very large value. The driver will then proceed to parse the header located at that position, which will either oops or process some random value. The fix is to check against sizeof(u64) rather than 0, which the driver currently does. The issue exists since the introduction of the driver. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: usb: aqc111: verifique el paquete para corregir el límite verdadero Si un dispositivo envía un paquete que está entre 0 y sizeof(u64), el valor pasado a skb_trim() como longitud se ajustará terminando como un valor muy grande. Luego, el controlador procederá a analizar el encabezado ubicado en esa posición, lo que procesará algún valor aleatorio. La solución es compararlo con sizeof(u64) en lugar de 0, como hace actualmente el controlador. • https://git.kernel.org/stable/c/84f2e5b3e70f08fce3cb1ff73414631c5e490204 https://git.kernel.org/stable/c/d69581c17608d81824dd497d9a54b6a5b6139975 https://git.kernel.org/stable/c/46412b2fb1f9cc895d6d4036bf24f640b5d86dab https://git.kernel.org/stable/c/82c386d73689a45d5ee8c1290827bce64056dddd https://git.kernel.org/stable/c/2ebf775f0541ae0d474836fa0cf3220e502f8e3e https://git.kernel.org/stable/c/ccab434e674ca95d483788b1895a70c21b7f016a •
CVSS: 7.0EPSS: 0%CPEs: 7EXPL: 0CVE-2024-27397 – netfilter: nf_tables: use timestamp to check for set element timeout
https://notcve.org/view.php?id=CVE-2024-27397
In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: use timestamp to check for set element timeout Add a timestamp field at the beginning of the transaction, store it in the nftables per-netns area. Update set backend .insert, .deactivate and sync gc path to use the timestamp, this avoids that an element expires while control plane transaction is still unfinished. .lookup and .update, which are used from packet path, still use the current time to check if the element has expired. And .get path and dump also since this runs lockless under rcu read size lock. Then, there is async gc which also needs to check the current time since it runs asynchronously from a workqueue. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nf_tables: use la marca de tiempo para verificar el tiempo de espera del elemento establecido. Agregue un campo de marca de tiempo al comienzo de la transacción y guárdelo en el área nftables per-netns. • https://git.kernel.org/stable/c/c3e1b005ed1cc068fc9d454a6e745830d55d251d https://git.kernel.org/stable/c/f8dfda798650241c1692058713ca4fef8e429061 https://git.kernel.org/stable/c/eaf1a29ea5d7dba8e84e9e9f3b3f47d0cd540bfe https://git.kernel.org/stable/c/7b17de2a71e56c10335b565cc7ad238e6d984379 https://git.kernel.org/stable/c/0d40e8cb1d1f56a994cdd2e015af622fdca9ed4d https://git.kernel.org/stable/c/b45176b869673417ace338b87cf9cdb66e2eeb01 https://git.kernel.org/stable/c/383182db8d58c4237772ba0764cded4938a235c3 https://git.kernel.org/stable/c/7395dfacfff65e9938ac0889dafa1ab01 •
