CVE-2025-38653

In the Linux kernel, the following vulnerability has been resolved: proc: use the same treatment to check proc_lseek as ones for proc_read_iter et.al Check pde->proc_ops->proc_lseek directly may cause UAF in rmmod scenario. It's a gap in proc_reg_open() after commit 654b33ada4ab("proc: fix UAF in proc_get_inode()"). Followed by AI Viro's suggestion, fix it in same manner.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: proc: usar el mismo tratamiento para verificar proc_lseek que para proc_read_iter, etc. Verificar pde->proc_ops->proc_lseek directamente puede causar UAF en el escenario rmmod. Se trata de una falla en proc_reg_open() después del commit 654b33ada4ab("proc: fix UAF in proc_get_inode()"). Siguiendo la sugerencia de AI Viro, se debe corregir de la misma manera.
