CVSS: 7.0EPSS: 0%CPEs: 10EXPL: 0CVE-2024-36883 – net: fix out-of-bounds access in ops_init
https://notcve.org/view.php?id=CVE-2024-36883
In the Linux kernel, the following vulnerability has been resolved: net: fix out-of-bounds access in ops_init net_alloc_generic is called by net_alloc, which is called without any locking. It reads max_gen_ptrs, which is changed under pernet_ops_rwsem. It is read twice, first to allocate an array, then to set s.len, which is later used to limit the bounds of the array access. It is possible that the array is allocated and another thread is registering a new pernet ops, increments max_gen_ptrs, which is then used to set s.len with a larger than allocated length for the variable array. Fix it by reading max_gen_ptrs only once in net_alloc_generic. If max_gen_ptrs is later incremented, it will be caught in net_assign_generic. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: corrige el acceso fuera de los límites en ops_init net_alloc_generic es llamado por net_alloc, que se llama sin ningún bloqueo. • https://git.kernel.org/stable/c/073862ba5d249c20bd5c49fc6d904ff0e1f6a672 https://git.kernel.org/stable/c/561331eae0a03d0c4cf60f3cf485aa3e8aa5ab48 https://git.kernel.org/stable/c/a2c82f7bee1ffa9eafa1fb0bd886a7eea8c9e497 https://git.kernel.org/stable/c/3cdc34d76c4f777579e28ad373979d36c030cfd3 https://git.kernel.org/stable/c/7b0e64583eab8c1d896b47e5dd0bf2e7d86ec41f https://git.kernel.org/stable/c/0c3248bc708a7797be573214065cf908ff1f54c7 https://git.kernel.org/stable/c/9518b79bfd2fbf99fa9b7e8e36bcb1825e7ba030 https://git.kernel.org/stable/c/2d60ff5874aefd006717ca5e22ac1e25e • CWE-787: Out-of-bounds Write •
