CVE-2024-41935
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to shrink read extent node in batches We use rwlock to protect core structure data of extent tree during its shrink, however, if there is a huge number of extent nodes in extent tree, during shrink of extent tree, it may hold rwlock for a very long time, which may trigger kernel hang issue. This patch fixes to shrink read extent node in batches, so that, critical region of the rwlock can be shrunk to avoid its extreme long time hold.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: f2fs: corrección para reducir el nodo de extensión de lectura en lotes Usamos rwlock para proteger los datos de la estructura central del árbol de extensión durante su reducción, sin embargo, si hay una gran cantidad de nodos de extensión en el árbol de extensión, durante la reducción del árbol de extensión, puede mantener rwlock durante mucho tiempo, lo que puede desencadenar un problema de bloqueo del kernel. Este parche corrige la reducción del nodo de extensión de lectura en lotes, de modo que la región crítica de rwlock se pueda reducir para evitar su retención de tiempo extremadamente largo."
