In the Linux kernel, the following vulnerability has been resolved: net: stmmac: xgmac: fix handling of DPP safety error for DMA channels Commit 56e58d6c8a56 ("net: stmmac: Implement Safety Features in XGMAC core") checks and reports safety errors, but leaves the Data Path Parity Errors for each channel in DMA unhandled at all, lead to a storm of interrupt. Fix it by checking and clearing the DMA_DPP_Interrupt_Status register. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: stmmac: xgmac: corrige el manejo del error de seguridad DPP para canales DMA. El commit 56e58d6c8a56 ("net: stmmac: Implement Safety Features in XGMAC core") verifica e informa errores de seguridad, pero deja sin controlar los errores de paridad de ruta de datos para cada canal en DMA, lo que provoca una tormenta de interrupciones.

https://notcve.org/view.php?id=CVE-2024-26683
In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: detect stuck ECSA element in probe resp We recently added some validation that we don't try to connect to an AP that is currently in a channel switch process, since that might want the channel to be quiet or we might not be able to connect in time to hear the switching in a beacon. This was in commit c09c4f31998b ("wifi: mac80211: don't connect to an AP while it's in a CSA process"). However, we promptly got a report that this caused new connection failures, and it turns out that the AP that we now cannot connect to is permanently advertising an extended channel switch announcement, even with quiet. The AP in question was an Asus RT-AC53, with firmware 3.0.0.4.380_10760-g21a5898. As a first step, attempt to detect that we're dealing with such a situation, so mac80211 can use this later. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: "wifi: cfg80211: detect stuck ECSA element in probe resp". Recientemente agregamos alguna validación de que no intentamos conectarnos a un AP que se encuentra actualmente en un proceso de cambio de canal, desde entonces es posible que deseemos que el canal esté en silencio o que no podamos conectarnos a tiempo para escuchar el cambio en una baliza. Esto estaba en el commit c09c4f31998b ("wifi: mac80211: no se conecte a un AP mientras esté en un proceso CSA"). • https://git.kernel.org/stable/c/c09c4f31998bac6d73508e38812518aceb069b68 https://git.kernel.org/stable/c/ce112c941c2b172afba3e913a90c380647d53975 https://git.kernel.org/stable/c/177fbbcb4ed6b306c1626a277fac3fb1c495a4c7 •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-26682 – wifi: mac80211: improve CSA/ECSA connection refusal
https://notcve.org/view.php?id=CVE-2024-26682
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: improve CSA/ECSA connection refusal As mentioned in the previous commit, we pretty quickly found that some APs have ECSA elements stuck in their probe response, so using that to not attempt to connect while CSA is happening we never connect to such an AP. Improve this situation by checking more carefully and ignoring the ECSA if cfg80211 has previously detected the ECSA element being stuck in the probe response. Additionally, allow connecting to an AP that's switching to a channel it's already using, unless it's using quiet mode. In this case, we may just have to adjust bandwidth later. If it's actually switching channels, it's better not to try to connect in the middle of that. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: "wifi: mac80211: improve CSA/ECSA connection refusal". Como se mencionó en el commit anterior, descubrimos rápidamente que algunos AP tienen elementos ECSA atascados en su respuesta de sondeo, por lo que no se pueden usar si intentamos conectarnos mientras se realiza CSA, nunca nos conectaremos a dicho AP. • https://git.kernel.org/stable/c/c09c4f31998bac6d73508e38812518aceb069b68 https://git.kernel.org/stable/c/ea88bde8e3fefbe4268f6991375dd629895a090a https://git.kernel.org/stable/c/35e2385dbe787936c793d70755a5177d267a40aa •
