CVE-2025-39778

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: objtool, nvmet: Se corrige el acceso a la pila fuera de los límites en nvmet_ctrl_state_show(). La matriz csts_state_names[] solo tiene seis entradas dispersas, pero el código de iteración en nvmet_ctrl_state_show() itera siete, lo que resulta en una posible lectura de la pila fuera de los límites. Se soluciona. Se corrige la siguiente advertencia con un kernel UBSAN: vmlinux.o: advertencia: objtool: .text.nvmet_ctrl_state_show: final inesperado de sección.

In the Linux kernel, the following vulnerability has been resolved: objtool, nvmet: Fix out-of-bounds stack access in nvmet_ctrl_state_show() The csts_state_names[] array only has six sparse entries, but the iteration code in nvmet_ctrl_state_show() iterates seven, resulting in a potential out-of-bounds stack read. Fix that. Fixes the following warning with an UBSAN kernel: vmlinux.o: warning: objtool: .text.nvmet_ctrl_state_show: unexpected end of section

It was discovered that the CIFS network file system implementation in the Linux kernel did not properly verify the target namespace when handling upcalls. An attacker could use this to expose sensitive information. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
